You finally ordered that set of adjustable coilovers to get your ride sitting right and handling like it is on rails. Upgrading your suspension is one of the most rewarding modifications you can do, but it is also one of the most labor-intensive. Many enthusiasts wonder, how long does it take to install coilovers before they commit their entire Saturday to the garage.
We agree that nothing ruins a weekend faster than a “quick” job turning into a three-day ordeal because of a stuck bolt or a missing tool. We promise to break down the realistic timeframes for different skill levels and vehicle types so you can plan your install with confidence. This guide previews the essential tools, common time-wasters, and the step-by-step workflow used by professional technicians.
Whether you are working on a dedicated off-road rig or a street-tuned daily driver, knowing the timeline helps you work safely and efficiently. Let’s dive into the variables that dictate your time on the jack stands and how to avoid the pitfalls that keep cars stuck in the driveway.
Understanding the Baseline: how long does it take to install coilovers?
For most DIY mechanics working in a home garage, a full set of four coilovers typically takes between 4 to 8 hours to install. This estimate assumes you have a decent set of tools and a basic understanding of your vehicle’s suspension geometry. If you are a seasoned pro with a lift and air tools, you might finish the job in under 3 hours.
However, if this is your first time touching a control arm or a strut tower, expect to be on the higher end of that scale. Factors like vehicle age, rust, and the specific type of suspension—such as MacPherson struts versus a multi-link setup—dramatically impact the clock. It is always better to budget more time than you think you need to ensure every fastener is torqued correctly.
Remember that the physical installation is only part of the journey. You also need to factor in the time for ride height adjustments and the mandatory trip to the alignment shop. Rushing through suspension work often leads to safety issues or premature tire wear, so patience is your most valuable tool here.
The Skill Level Breakdown
A master technician in a fully equipped shop usually bills for 3 to 4 hours of labor for a standard coilover swap. They use pneumatic impacts and tall under-hoist stands that make the process much faster and more ergonomic. Their experience allows them to anticipate problems before they happen.
The average “weekend warrior” with a floor jack and a set of hand wrenches should plan for a full day. You will likely spend a significant amount of time double-checking torque specs and cleaning up old components. This extra time ensures that your new investment performs exactly as the manufacturer intended.
If you are a complete novice, consider inviting a more experienced friend to help. Having a second set of eyes can prevent common mistakes, such as installing a top hat incorrectly or stripping a sway bar link. In this scenario, 8 to 10 hours is a safe and low-stress estimate for the project.
Major Factors That Influence Your Installation Time
Not every car is built the same, and your environment plays a massive role in how smoothly the job goes. One of the biggest variables in how long does it take to install coilovers is the condition of the underbody. A car from the “rust belt” will require significantly more time than a clean vehicle from a dry climate.
The complexity of the suspension design is another major factor. A simple MacPherson strut system found on many front-wheel-drive cars is generally faster to swap than a complex double-wishbone setup. In some vehicles, you may even need to remove interior trim pieces to access the rear strut towers, adding an hour or more to the job.
Tool availability is the ultimate “time-multiplier” in any DIY project. If you are using a manual ratchet for every bolt, your arms will tire, and the clock will tick faster. Using a high-torque impact wrench can shave an hour off the total time just by speeding up the removal of stubborn lug nuts and mounting bolts.
Rust and Seized Hardware
Corrosion is the enemy of a quick suspension install. If your lower strut bolts are fused to the bushings, you might spend two hours on a single corner of the car. This is where heat from a torch or heavy-duty penetrant oils become essential equipment.
Always spray your suspension bolts with a high-quality penetrating lubricant 24 hours before you plan to start the work. This simple step can save you hours of frustration and prevent you from snapping a bolt off in the knuckle. Dealing with a broken bolt can easily double your total installation time.
Accessibility and Interior Teardown
Some modern cars require you to remove the rear seats or parcel shelf to reach the top mounting nuts. This is especially common in coupes and luxury sedans where suspension components are hidden for aesthetic reasons. Check a service manual or forum for your specific model to see if interior work is required.
If you have to pull out plastic clips and upholstery, work slowly to avoid breaking fragile tabs. This process usually adds 30 to 60 minutes to the front end and back end of the job. Keeping your trim tools handy will make this phase much smoother and prevent damage to your interior.
The Essential Tool List for a Faster Install
Having the right tools ready to go is the best way to minimize the time you spend under the car. You don’t need a professional shop, but a few key items will make the process much safer. Ensure your workstation is organized before you even loosen the first lug nut.
- Floor Jack and Jack Stands: Never work under a car supported only by a jack. Use four sturdy stands to keep the vehicle level.
- Impact Wrench: An electric or air-powered impact is a massive time-saver for removing stubborn suspension bolts.
- Torque Wrench: Critical for safety; you must tighten every bolt to the manufacturer’s specific foot-pounds.
- Breaker Bar: For those bolts that an impact can’t reach or won’t budge.
- Socket Set and Wrenches: Deep sockets are often required for the long studs found on strut mounts.
- Penetrating Oil: Such as PB Blaster or Liquid Wrench to loosen rust.
- Anti-Seize Lubricant: Apply this to your new coilover threads to make future adjustments much easier.
If your new coilovers did not come with pre-installed top hats, you will also need a spring compressor. Using this tool requires extreme caution, as a compressed spring holds an immense amount of energy. Budget an extra hour if you need to swap your OEM top hats over to the new assemblies.
Step-by-Step Installation Workflow
A systematic approach is the secret to a professional-grade result. By following a consistent workflow, you reduce the chance of forgetting a step or having to redo a corner. We recommend finishing one side of an axle completely before moving to the other side.
1. Vehicle Preparation and Safety
Park on a flat, level surface and engage the parking brake. Loosen the lug nuts while the tires are still on the ground, then lift the vehicle and secure it on jack stands. Remove the wheels and set them aside—they can actually serve as an extra safety barrier under the frame.
Open the hood and locate the top mounting nuts for the front struts. If you have to remove any plastic cowls or braces, do that now. Spray all the lower mounting hardware with your penetrant oil one last time to ensure everything is ready to move.
2. Removing the Old Suspension
Start by disconnecting any brake lines or ABS sensor wires attached to the strut body. Failing to do this can result in a snapped wire as the suspension drops. Support the lower control arm with a jack so it doesn’t fall abruptly when you pull the main bolts.
Remove the lower mounting bolts first, then move to the top nuts. Carefully lower the old strut assembly out of the wheel well. If the assembly is stuck, a few taps with a rubber mallet on the knuckle usually frees it without causing damage.
3. Installing the New Coilovers
Lift the new coilover into place and hand-tighten the top nuts to hold it in position. Align the lower mount with the knuckle and slide the bolts through. It often helps to use a floor jack to slightly compress the suspension until the bolt holes line up perfectly.
Once all bolts are in place, use your torque wrench to tighten them to the specific settings found in your vehicle’s service manual. Reattach any brake lines or sensor clips. Repeat this process for all four corners, keeping a close eye on any left/right specific markings on the parts.
Common Pitfalls That Add Hours to the Job
Even the best-laid plans can go sideways when you start taking things apart. One of the most common delays during a coilover installation is realizing you have the wrong parts or missing hardware. Always inventory your kit before you disable your only mode of transportation.
Another time-sink is failing to set the initial preload on the springs. Most coilovers require a specific amount of tension on the spring before they are installed. If you skip this, you will have to take the suspension back apart or deal with annoying clunking noises later.
Do not forget to check your clearances. Once the car is back on its wheels, check if the tires rub against the new coilover body or the fender liners. Adjusting the height while the car is on the ground is difficult, so try to get your base settings close while the car is still on stands.
Stripped Threads and Rounded Bolts
Using the wrong size socket—like a 14mm on a 9/16 bolt—is a recipe for disaster. Always ensure your tools fit snugly on the hardware. If a bolt feels like it is going to strip, stop immediately and apply more heat or lubricant.
If you do strip a bolt, you may need a bolt extractor or a drill to remove it. This can add hours to your timeline and may require a trip to the hardware store for replacement Grade 8 or Grade 10.9 hardware. Work slowly and feel the resistance of the metal.
Forgetting the Alignment
Changing your ride height completely alters your toe, camber, and caster settings. Driving a car that hasn’t been aligned is dangerous and will ruin your tires in a matter of days. Budget time and money to visit a professional alignment shop immediately after your install.
While some people try to perform a “string alignment” at home, it is rarely accurate enough for a performance setup. A professional laser alignment ensures your car tracks straight and handles predictably. This is the final step that completes the project correctly.
Frequently Asked Questions About how long does it take to install coilovers
Can I install coilovers by myself in one day?
Yes, most DIYers can complete a full coilover install in 6 to 8 hours. If you start early in the morning and have all your tools ready, you should have the car back on the road by dinner time. However, always have a backup plan in case you encounter a seized bolt.
Do I need a lift to install coilovers quickly?
A lift makes the job much easier on your back and neck, but it is not strictly necessary. Quality jack stands and a high-lift floor jack provide enough clearance for most suspension work. Working on the ground might add about 20% more time due to the limited range of motion for your tools.
Should I replace other parts while I am in there?
Absolutely. If your sway bar end links or control arm bushings look worn, replace them during the install. Since you already have the suspension apart, adding these parts only takes a few extra minutes but can save you hours of repeated labor in the future.
How much does it cost to have a shop do the install?
Most shops charge between $400 and $800 for labor, depending on the complexity of the vehicle. This usually does not include the cost of the alignment. If your time is limited or you don’t have the tools, paying a professional is a valid way to ensure the job is done safely.
Final Thoughts on Your Suspension Upgrade
Upgrading your suspension is a major milestone for any vehicle owner. While the question of how long does it take to install coilovers depends on many variables, preparation is the ultimate shortcut. By cleaning your parts, soaking your bolts, and organizing your tools, you turn a potential nightmare into a successful Saturday project.
Take your time with the adjustments and never compromise on safety. Once the job is done and the alignment is set, the improved handling and aggressive stance will make every hour spent in the garage worth it. Your car will feel transformed, providing a more connected driving experience whether you are hitting the track or the trails.
Stay safe, double-check your torque specs, and enjoy the ride! If you ever feel overwhelmed, don’t hesitate to reach out to a local mechanic or an experienced friend. There is no shame in asking for help to get the job done right. Now, get out there and start wrenching!
