Why Upgrade to Hood Struts? Beyond Basic Convenience

The humble prop rod has served us for decades, but it’s far from ideal. For anyone who spends significant time under the hood, especially off-roaders and DIY mechanics, hood struts offer a world of benefits. They transform a mundane task into a much safer and more efficient experience.

Here’s why making the switch is a smart move:

Enhanced Safety: A prop rod can slip, especially on uneven ground or in windy conditions, leading to a falling hood and potential injury. Struts provide a secure, controlled lift.
Hands-Free Operation: Imagine needing both hands to work. With struts, your hood stays open on its own, freeing you up to focus on the task at hand.
Improved Access: Struts often allow the hood to open wider than a prop rod, giving you better access to the engine bay. This is crucial for larger repairs or when working in tight spaces.
Modern Aesthetics: Let’s be honest, hood struts just look cleaner and more professional than a clunky metal stick. They give your vehicle a more refined, modern feel.
Durability and Reliability: Quality gas struts are designed to last, providing consistent performance for years, even in challenging environments like dusty trails or extreme temperatures.

For off-road enthusiasts, this upgrade is particularly beneficial. When you’re miles from civilization and need to check under the hood, reliability is paramount. You don’t want a gust of wind or an unstable surface to compromise your safety.

Understanding Hood Strut Systems and Components

Before diving into how to install hood struts, it’s helpful to understand what you’re working with. Most hood strut systems consist of a few key components designed to work together seamlessly. Familiarizing yourself with these parts will make the installation process much smoother.

The Anatomy of a Hood Strut Kit

A typical hood strut kit includes:

Gas Struts (or Gas Springs): These are the core of the system. Each strut is a sealed cylinder filled with pressurized gas (usually nitrogen) and oil, containing a piston that extends and retracts. They provide the lifting force and dampening.
Mounting Brackets: These metal brackets attach to specific points on your vehicle’s hood and fender/body. They are custom-designed for your vehicle’s make and model to ensure proper fitment and alignment.
Ball Studs: These small, spherical studs are often pre-attached to the brackets or are separate components that thread into the brackets. The end of the gas strut snaps onto these ball studs, allowing for articulation.
Hardware: This includes bolts, nuts, washers, and sometimes clips or spacers needed to secure the brackets to your vehicle.

Most kits are designed for specific vehicles. This ensures the correct strut length, force, and bracket design for your hood’s weight and mounting points. Avoid generic kits unless they explicitly state compatibility with your vehicle.

Essential Tools and Materials for the Job

Preparation is key to any successful DIY project. Having all your tools and materials ready before you start will save you time and frustration. Gather these items before you begin to install hood struts.

Here’s what you’ll likely need:

New Hood Strut Kit: Ensure it’s the correct one for your vehicle’s make, model, and year.
Basic Socket/Wrench Set: You’ll need various sizes to remove existing bolts and secure new hardware. A ratcheting wrench can be particularly helpful in tight spots.
Flathead Screwdriver: Useful for prying off plastic clips or carefully separating components.
Torx or Allen Wrenches: Some vehicles or kits might use these fasteners. Check your kit’s instructions.
Measuring Tape: Helpful for confirming mounting locations or strut length if troubleshooting.
Masking Tape or Marker: To mark existing bolt positions if needed.
Clean Rags: For wiping down surfaces and cleaning up any grime.
Penetrating Oil (e.g., WD-40): Useful for loosening stubborn or rusted bolts.
Dielectric Grease (optional): Can be applied to ball studs to reduce friction and extend strut life.
Safety Glasses: Always protect your eyes, especially when working with tools and under tension.
Gloves: Protect your hands from grease and sharp edges.
A Helper: Absolutely crucial! You’ll need someone to hold the hood securely open while you work.

Always refer to your specific kit’s instructions as they may have unique tool requirements or additional recommendations. Safety is paramount, so don’t skip the safety gear.

Preparing for a Safe Hood Strut Installation

Safety is always our top priority at FatBoysOffroad. Before you even think about touching a wrench, take a moment to prepare your workspace and your vehicle. This ensures a smooth process and prevents accidents while you learn how to install hood struts.

Follow these crucial steps:

Park on Level Ground: Ensure your vehicle is on a flat, stable surface. This prevents unexpected movement and keeps the hood stable during the process.
Engage Parking Brake: Always engage the parking brake for added safety.
Open the Hood: Fully open your vehicle’s hood and support it securely. This is where your helper comes in! Your helper should hold the hood firmly throughout the entire installation, especially when you remove the existing prop rod or during strut changes.
Disconnect Battery (Optional but Recommended): If you’re working near electrical components or need to drill, disconnecting the negative battery terminal is a good safety practice.
Clear the Work Area: Remove any tools, clutter, or distractions from around the engine bay. You’ll need clear access to the mounting points.
Review Instructions: Read your specific hood strut kit’s instructions thoroughly. Each kit can have subtle differences in bracket placement or hardware.
Identify Mounting Points: Most kits utilize existing bolt holes on your hood and fender/body. Locate these points as described in your kit’s instructions. Sometimes, a template is provided for drilling new holes, but many modern kits are “no-drill.”

Never rely solely on the existing prop rod once you start removing components. A falling hood can cause serious injury or damage. Your helper is your most valuable asset during this project.

How to Install Hood Struts: A Step-by-Step Guide

Now for the main event! This section provides a detailed, actionable guide on how to install hood struts. We’ll break it down into manageable steps, focusing on clarity and safety. Remember to work on one side of the vehicle at a time.

Step 1: Install the Lower Brackets

Start with the brackets that attach to the fender or vehicle body:

Locate Lower Mounting Point: Refer to your kit’s instructions to find the correct bolt hole on your vehicle’s fender or inner fender well. This is often an existing bolt used for other components.
Remove Existing Bolt: Carefully remove the bolt from this mounting point using your socket or wrench. If it’s stubborn, apply a little penetrating oil and let it sit.
Position Lower Bracket: Place the new lower mounting bracket over the bolt hole. Ensure it’s oriented correctly, usually with the ball stud pointing upwards and slightly inwards towards the engine bay.
Secure Lower Bracket: Reinsert the original bolt (or the new hardware provided in your kit) through the bracket and tighten it down. Do not overtighten, but ensure it’s snug and secure.
Install Ball Stud (if separate): If your ball stud is not pre-attached, thread it securely into the bracket.

Repeat this process for the lower bracket on the other side of the vehicle. This ensures both sides are ready for the struts.

Step 2: Install the Upper Brackets

Next, move to the hood-side brackets:

Locate Upper Mounting Point: With your helper still securely holding the hood, find the designated mounting point on the underside of the hood. This might involve removing an existing bolt or a small plastic plug.
Position Upper Bracket: Align the upper bracket with the mounting holes. Pay close attention to its orientation; the ball stud should typically point downwards and slightly towards the engine bay, ready to receive the strut.
Secure Upper Bracket: Use the provided hardware (bolts, washers) to firmly attach the bracket to the hood. If you removed an existing bolt, ensure the new hardware is appropriate or reuse the original if specified.
Install Ball Stud (if separate): If your ball stud is not pre-attached, thread it securely into the bracket.

Again, repeat this for the upper bracket on the opposite side. Double-check that all brackets are facing the correct direction and are securely fastened.

Step 3: Attach the Hood Struts

This is where your helper is absolutely essential. Do not attempt this step alone:

Start with One Strut: Have your helper firmly hold the hood in its fully open position.
Orient the Strut: Gas struts are typically installed with the fatter cylinder end pointing upwards, and the thinner rod end pointing downwards. This helps with lubrication and longevity. Check your kit’s instructions for specific orientation.
Attach to Ball Studs: Carefully align one end of the strut with a ball stud. Press the strut’s socket firmly onto the ball stud until it clicks into place. You might need to apply a fair amount of pressure.
Repeat for Other End: Once one end is attached, align the other end of the strut with its corresponding ball stud. Gently compress or extend the strut as needed to snap it onto the second ball stud. This can sometimes be the trickiest part, requiring careful alignment and steady pressure.
Test the First Strut: With one strut installed, you can gently lower the hood a small amount to feel the strut’s tension. Your helper should still maintain control of the hood.

Now, repeat the entire strut attachment process for the second hood strut on the other side. Once both struts are installed, you can remove the prop rod if it’s still in place.

Step 4: Test and Adjust

The final crucial step is to test your new hood strut system:

Initial Lowering: With your helper’s assistance, slowly and carefully lower the hood. It should feel controlled and smooth.
Full Cycle Test: Raise the hood fully, then lower it completely several times. Observe how the struts operate. Do they hold the hood securely at various heights? Does it close smoothly without excessive force?
Check Alignment: Ensure the hood closes evenly and that there are no new gaps or misalignments. The struts should not interfere with any other components.
Lubricate (Optional): If your kit didn’t come with pre-lubricated ball studs, a small dab of dielectric grease can help ensure smooth operation and prevent squeaks.

If the hood doesn’t stay up, or if it’s difficult to close, recheck your installation. Ensure all brackets are secure, struts are correctly oriented, and you have the right kit for your vehicle. Sometimes new struts need a few cycles to “break in” and operate optimally.

Troubleshooting Common Hood Strut Issues

Even with the best instructions, sometimes things don’t go exactly as planned. Here are a few common issues you might encounter after you install hood struts and how to tackle them.

Hood Doesn’t Stay Up

This is the most common problem:

Incorrect Strut Force: The struts might not be strong enough for your hood’s weight. This can happen if you have a heavier aftermarket hood or if you purchased generic struts not rated for your vehicle.
Improper Installation: Recheck that the struts are fully seated on the ball studs and that the brackets are firmly secured.
Strut Orientation: Ensure the cylinder (fatter) end is generally pointing upwards. Incorrect orientation can sometimes affect performance.
Defective Struts: Though rare, a new strut could be faulty. If all else checks out, contact the manufacturer.

Hood Is Hard to Close

If you’re fighting to get the hood down:

Struts Are Too Strong: The struts might be rated for a heavier hood than yours, or they might be new and stiff. They usually soften slightly after a few uses.
Misalignment: Check if the brackets are causing any binding or if the hood is catching on anything as it closes.

Squeaking or Grinding Noises

Annoying sounds can often be fixed easily:

Lack of Lubrication: Apply a small amount of dielectric grease or silicone spray to the ball studs and strut ends.
Loose Brackets: Ensure all mounting bolts are tight.
Interference: Check if the strut or bracket is rubbing against another part of the vehicle.

If you encounter persistent issues, consult your kit’s instructions or the manufacturer. Sometimes, a quick call to customer support can resolve complex problems.

Maintenance and Care for Your New Hood Struts

Once you’ve successfully learned how to install hood struts, a little ongoing care will ensure they last for years. These simple maintenance tips will keep your system operating smoothly, especially for off-roaders whose vehicles face harsher conditions.

Here’s what to do:

Keep Them Clean: Regularly wipe down the strut rods and cylinders with a clean, damp cloth. Dirt, dust, and grime can abrade the seals and lead to premature failure.
Inspect Regularly: During your routine under-hood checks, take a moment to inspect the struts. Look for any signs of leakage (oil residue), rust, bent rods, or loose mounting hardware.
Lubricate Ball Studs: Every few months, or if you notice any stiffness or squeaking, apply a small amount of dielectric grease or a silicone-based lubricant to the ball studs where the strut snaps on. Avoid petroleum-based lubricants as they can damage rubber seals.
Check for Wear: Over time, the plastic or metal ends of the struts that snap onto the ball studs can wear. If they become loose or show cracks, consider replacement.
Avoid Over-Extension: While most struts have internal stops, avoid forcing your hood open beyond its natural stopping point.

For off-road vehicles, pay extra attention after dusty or muddy excursions. A quick rinse and wipe down can significantly extend the life of your struts and prevent premature wear from abrasive particles.

Off-Roading Considerations for Hood Struts

For our FatBoysOffroad community, an important question is how hood struts hold up to the rigors of off-roading. The good news is that quality struts are quite robust, but there are a few things to keep in mind.

Consider these points for trail use:

Durability: Choose a kit from a reputable brand known for quality. These struts are often designed to withstand vibrations and minor impacts.
Dust and Mud: As mentioned in maintenance, dust and mud can be detrimental to strut seals. Regular cleaning is even more critical for off-road vehicles.
Extreme Articulation: If your vehicle’s frame or body undergoes extreme twisting and articulation during off-roading, ensure your strut mounting points are robust. In rare cases of severe frame flex, very poorly designed strut mounts could theoretically experience stress, but this is highly unlikely with a properly designed, vehicle-specific kit.
Water Crossings: Submerging the engine bay in deep water can expose the struts to contamination. Again, cleaning afterwards is key.
Hood Weight: If you’ve added heavy accessories to your hood (e.g., a high-lift jack mount, extra lights), you might need heavy-duty struts specifically designed for increased weight. Standard struts might struggle to hold up an overloaded hood.

Ultimately, hood struts are a fantastic upgrade for off-road vehicles, enhancing safety and convenience during trailside repairs or inspections. Just be mindful of their exposure to the elements and perform routine checks.

Frequently Asked Questions About Hood Struts

Got more questions about this handy upgrade? Here are some common queries we hear about installing and using hood struts.

Are hood struts universal, or do I need a specific kit?

Generally, no, hood struts are not universal. You absolutely need a kit designed specifically for your vehicle’s make, model, and year. The length, force (pressure), and mounting bracket designs are all unique to ensure proper fitment and function.

How long do hood struts typically last?

With proper installation and maintenance, quality hood struts can last anywhere from 5 to 10 years, or even longer. Factors like frequency of use, exposure to harsh elements, and proper orientation during installation can affect their lifespan.

Can I install hood struts by myself, or do I need a professional?

Installing hood struts is a very common DIY project and is well within the capabilities of most weekend mechanics. However, you must have a helper to safely hold the hood during the installation process. Attempting it alone can be dangerous.

What if my hood doesn’t stay up after installation?

If your hood isn’t staying up, first re-check all connections to ensure the struts are fully snapped onto the ball studs and all brackets are tight. Confirm the struts are oriented correctly (usually cylinder up). If these are correct, the struts might be faulty or not strong enough for your hood’s weight (e.g., if you have a heavy aftermarket hood). Contact the kit manufacturer for support.

Do hood struts cause any damage to the hood or body?

When properly installed, hood struts should not cause any damage. The kits are designed to distribute the load correctly. Problems typically arise from incorrect installation, using the wrong kit, or overtightening bolts, which can deform mounting points. Always follow the instructions carefully.
