Why Bushwacker Fender Flares? Benefits & Considerations

Before we dive into the nuts and bolts, let’s talk about the significant benefits of how to install Bushwacker fender flares on your vehicle. These aren’t just for looks; they offer crucial functionality, especially for off-road enthusiasts.

Aggressive Aesthetics: Bushwacker flares are synonymous with a rugged, custom look. They give your truck or SUV a broader, more commanding presence.
Legal Compliance: Many states have laws requiring tires to be covered by the fender. If you’ve upgraded to wider tires, flares can ensure you stay street legal.
Increased Tire Clearance: Some flare designs, particularly cut-out styles, can provide additional tire clearance for larger setups and more articulation off-road.

Consider the style that best fits your needs: Pocket Style, Extend-A-Fender, or Flat Style, each offering different levels of coverage and aesthetic appeal. Choosing the right flare for your application is the first step towards a successful install.

Gearing Up: Tools, Materials, and Pre-Installation Checks

A successful installation begins with proper preparation. This section is your essential how to install Bushwacker fender flares guide for gathering everything you’ll need. Don’t rush this step!

Essential Tools You’ll Need

Safety glasses and gloves
Drill and various drill bits (typically 1/4″ and 5/16″, check instructions)
Socket wrench set (metric and standard)
Torque wrench
Phillips head screwdriver
Flathead screwdriver or trim removal tool
Utility knife or razor blade
Measuring tape
Marker or grease pencil
Rubbing alcohol or automotive cleaner
Clean rags
Optional: Heat gun (for trimming rubber seals)

Materials to Have on Hand

Your new Bushwacker fender flares (verify all parts are included)
All hardware supplied with the flares (bolts, washers, nuts, clips)
Rubber trim/seal (pre-installed or separate)
Painter’s tape or masking tape
Rust-preventative paint or primer (for any drilled holes)

Pre-Installation Vehicle Preparation

Clean Your Vehicle: Thoroughly wash and dry the areas around your wheel wells. This ensures good adhesion for seals and prevents grime from getting into new drill holes.
Inspect Your Flares: Unbox your Bushwacker flares and check for any damage or missing parts. Lay them out to get familiar with which flare goes on which wheel.
Read the Instructions: Every Bushwacker kit is vehicle-specific. Always read the manufacturer’s detailed instructions first. They often contain crucial model-specific steps and torque specifications.
Test Fit (Optional but Recommended): Temporarily hold each flare in place to get a feel for its fitment. This helps identify any potential issues before you start drilling.

The Step-by-Step Guide: How to Install Bushwacker Fender Flares

Now for the main event! This detailed section will guide you through how to install Bushwacker fender flares on your vehicle, focusing on accuracy and safety. We’ll generally cover the process, but remember to always consult your specific kit’s instructions for exact details.

Step 1: Preparing the Flares – Attaching the Edge Trim

Most Bushwacker flares come with a separate rubber edge trim that needs to be installed. This trim protects your vehicle’s paint and creates a tight seal.

Carefully unroll the trim.
Starting at one end, align the trim with the edge of the flare.
Press firmly to seat the trim completely around the flare’s edge.
Use a utility knife to trim any excess, ensuring a clean, flush joint. A heat gun can sometimes help the trim conform better to tight curves.

Step 2: Removing Existing Components

You’ll likely need to remove existing mud flaps, splash guards, or even factory fender flares before installing your new Bushwackers.

Use a trim removal tool or screwdriver to carefully pry off plastic clips.
Unbolt any fasteners holding existing components.
Keep track of removed hardware; you may reuse some of it, or you might need to plug existing holes later.

Step 3: Front Fender Flare Installation

The front flares often require more attention due to bumper integration and tighter spaces.

Clean the Area: Ensure the mounting surface on the vehicle is clean and dry.
Align the Flare: Carefully position the front flare onto the fender. Use painter’s tape to hold it in place temporarily, ensuring it’s level and flush.
Mark Drill Points: Following your kit’s instructions, use a marker to mark the drilling locations through the flare’s pre-drilled holes onto your vehicle’s sheet metal.
Drill Pilot Holes: *Safety First: Wear eye protection!* Using the recommended drill bit size (often 1/4″), carefully drill pilot holes at your marked spots. Be mindful of wiring or components behind the fender.
Protect Drilled Holes: Apply rust-preventative paint or primer to the raw edges of your newly drilled holes. This is a critical step for preventing future corrosion.
Secure the Flare: Attach the flare using the supplied hardware. Start all bolts by hand to prevent cross-threading.
Tighten Hardware: Gradually tighten all fasteners, working from the center outwards. Use a torque wrench if specific torque specs are provided. Avoid over-tightening.

Step 4: Rear Fender Flare Installation

Rear flares typically follow a similar process but may have different mounting points or fewer existing components to remove.

Repeat Cleaning & Alignment: Clean the rear fender area and carefully align the rear flare.
Mark & Drill: Mark the drill points as per instructions, drill pilot holes, and apply rust-preventative paint.
Secure the Flare: Install the supplied hardware, ensuring a snug fit. Again, tighten gradually and avoid over-tightening.

Step 5: Final Checks and Adjustments

Once all flares are installed, take a step back and perform a thorough inspection.

Check All Fasteners: Ensure all bolts, clips, and screws are securely tightened.
Inspect Gaps: Look for any noticeable gaps between the flare and the body. Minor adjustments might be possible by loosening and re-tightening fasteners.
Wipe Down: Clean any marker residue or fingerprints.

Troubleshooting Common Problems During Installation

Even with a detailed how to install Bushwacker fender flares guide, you might encounter a few snags. Here are some common problems with how to install Bushwacker fender flares and how to address them.

Misaligned Holes: If a drilled hole doesn’t perfectly align, try slightly enlarging the hole in the flare (not the vehicle) with a file or larger drill bit. Sometimes, the vehicle’s sheet metal might need a very slight adjustment, but proceed with caution.
Flare Not Sitting Flush: This could be due to uneven pressure during tightening, or the edge trim not being fully seated. Loosen fasteners, press the flare firmly against the body, and re-tighten. Ensure the rubber trim is fully compressed.
Hardware Issues: If a bolt strips, stop immediately. You may need to use a slightly larger self-tapping screw or, for more serious issues, consult a professional. Always use the provided hardware as it’s designed for the application.
Difficulty with Edge Trim: If the trim doesn’t want to conform to tight curves, gently heat it with a heat gun on a low setting. This makes the rubber more pliable. Be careful not to overheat or melt it.

Remember, patience is key. Don’t force anything. If you’re unsure, re-read your kit’s instructions or search for vehicle-specific installation videos online.

Post-Installation Care & Best Practices

Your new Bushwacker flares are installed, now how do you keep them looking great? This section covers your how to install Bushwacker fender flares care guide and how to install Bushwacker fender flares best practices for longevity.

Regular Cleaning: Wash your flares regularly with mild soap and water, just like the rest of your vehicle. Pay attention to the areas where the flares meet the body, as dirt and grime can accumulate there.
UV Protection: Bushwacker flares are durable, but prolonged UV exposure can cause fading over time. Consider using a UV protectant specifically designed for automotive plastics to maintain their finish.
Periodic Inspection: Every few months, check all mounting hardware to ensure it remains tight. Off-roading can cause vibrations that might loosen fasteners.
Address Damage Promptly: If a flare gets scratched or scuffed, address it quickly. Bushwacker offers touch-up paints and repair kits for their textured finishes.

For a sustainable how to install Bushwacker fender flares approach, consider the durability of the product. Bushwacker flares are built to last, reducing the need for frequent replacements. When it comes to being eco-friendly how to install Bushwacker fender flares, ensure proper disposal of any old mud flaps or plastic components you removed. Recycle them if local facilities allow, or dispose of them responsibly.

Pro Tips for a Flawless Finish

Here are some additional how to install Bushwacker fender flares tips from the FatBoysOffroad crew to take your installation from good to great.

Pre-Assemble Hardware: If your kit involves multiple pieces of hardware for each mounting point (e.g., bolt, washer, nut), assemble them loosely before you get under the vehicle. This saves time and fumbling.
Tape for Precision: Use painter’s tape not just to hold the flare, but also to mark your intended drill line or cut line if any trimming is required. This provides a clear visual guide.
Use a Second Pair of Hands: While many steps can be done solo, having a friend help hold the flares in place during alignment and initial tightening can make a huge difference.
Consider Undercoating: If you live in an area with harsh winters or frequently go off-road, applying an undercoating or rust-proofing spray to the inner fender wells (after cleaning and before flare installation) can provide an extra layer of protection against corrosion.
Double-Check Torque Specs: If your instructions provide specific torque settings for fasteners, use your torque wrench. This prevents both overtightening (which can strip threads or crack plastic) and undertightening (which can lead to loose flares).
