Acura Integra Suspension Strut Replacement Guide (1986-2001)
Restore your Integra's sharp handling and ride quality by choosing the right replacement struts.
- For OEM-like performance, KYB is the most recommended aftermarket brand for the 1986-2001 Integra.
- Complete strut assemblies (including spring and mount) are safer and much faster for DIY installation.
- Always get a wheel alignment after replacing struts to prevent premature tire wear.
- Symptoms like a bouncy ride, clunking noises, and nose-diving during braking are clear signs that your struts need replacement.
Is It Time to Replace Your Integra's Struts?
As your Integra ages, its struts wear out gradually. You might not notice the slow decline in ride quality until it becomes a real problem. Worn struts don't just make the ride uncomfortable; they can affect your car's stability and safety. Look for these common symptoms:
- Bouncy or Floating Ride: If your car continues to bounce up and down after hitting a bump, the struts are likely worn and no longer damping suspension movement.
- Nose-Diving or Rear-Squatting: Does the front end of your car dip hard when you brake? Or does the rear end sag when you accelerate? This indicates the struts aren't controlling weight transfer properly.
- Unusual Noises: A clunking or knocking sound when you drive over bumps can be caused by worn internal components of the strut or loose mounting hardware.
- Poor Handling: If the car sways, feels unstable in corners, or the steering feels loose, your struts may be to blame.
- Uneven Tire Wear: Worn struts can cause the tires to bounce, leading to scalloped or cupped wear patterns on the tread.
- Visible Leaks: Look at the strut body itself. If you see oily fluid leaking out, the seals have failed, and the strut needs immediate replacement.
A Note on Terminology
While commonly called "struts," the components on a double-wishbone suspension like the Integra's are technically "coil-over shock absorbers." 🎬 See how to replace the front suspension on a GSR model. Unlike a MacPherson strut system, they are not a structural part of the steering geometry. However, for shopping purposes, most manufacturers and retailers list them as struts.
Choosing the Right Aftermarket Strut for Your Integra
For a vehicle like the 1986-2001 Integra, original equipment (OEM) parts from Acura may be expensive or discontinued. The aftermarket offers a wide range of options that can meet or exceed original performance, often at a better price. Here’s a breakdown of the brands available:
Brand Quality Tiers
Tier 1: OEM-Equivalent or Better
- KYB (Kayaba): Widely regarded as an OEM supplier for many Japanese automakers, KYB is a top choice for Integra owners. The Excel-G series is designed to restore original factory handling and control characteristics. Many forum users recommend KYB for its quality, durability, and performance, considering it a reliable and affordable way to get OEM-like or better ride quality.
Tier 2: Standard Aftermarket Replacement
- Monroe: A well-known brand offering a balance of quality and affordability. Their OESpectrum and Gas-Matic lines are designed as reliable OE replacements that provide good handling and control for daily driving. Some users report their "Quick-Strut" assemblies can raise ride height slightly and may not feel as sporty as other options, but generally provide a comfortable ride.
Tier 3: Economy Options
- FCS Struts & PRT (Performance Ride Technology): These brands offer some of the most budget-friendly options. They are often sold as complete strut assemblies, which simplifies installation. While they can be a good short-term solution to replace completely failed struts, some owners report they may not last as long or provide the same ride quality as higher-tier brands. They are a practical choice if you're on a tight budget or planning to sell the vehicle soon.
Bare Strut vs. Complete Assembly
You can buy a "bare" strut (the shock absorber part) or a "complete strut assembly." A complete assembly includes the strut, coil spring, and top mount, all pre-assembled. While more expensive upfront, assemblies are much easier and safer to install, as you don't need a dangerous spring compressor tool. This can reduce installation time from several hours to less than one.

For the 1986-2001 Acura Integra, there are no major open recalls specifically for suspension struts. Most recalls and Technical Service Bulletins (TSBs) for vehicles of this age have long since been addressed. A TSB from 1997 mentioned rear trailing arm bushing noise, but this is separate from the strut itself. Any recalls you find for the "Acura Integra" are for much newer models (2023 and later) and do not apply to the 1986-2001 generation.
Cost of Replacing Acura Integra Struts
| Part Type | Estimated Cost (Per Corner) | Notes |
|---|---|---|
| New Aftermarket (Bare Strut) | $40 - $110 | Requires reusing your old spring and mount. Requires a spring compressor. |
| New Aftermarket (Complete Assembly) | $70 - $180 | Easiest to install; includes new spring and mount. |
| New OEM (If Available) | $250+ | May be difficult to find for older models. |
| Shop Labor | $100 - $200 | Per corner. Total labor for all four can be $400-$600+. |
Frequently Asked Questions (FAQ)
Do I need to replace all four struts at once?
It is highly recommended to replace struts in pairs (both front or both rear) to ensure even handling and stability. Replacing all four at the same time is the best practice for restoring the vehicle's original ride and handling characteristics.
Do I need a wheel alignment after replacing my struts?
Yes. Replacing any major suspension component, including struts, will affect your vehicle's alignment angles. You should always get a professional four-wheel alignment after the job is done to prevent uneven tire wear and ensure proper handling.
Can I reuse my old coil springs?
If you are buying bare struts, you will need to reuse your original coil springs. This requires a special tool called a spring compressor, which can be dangerous if not used correctly. If your springs are visibly rusted, cracked, or sagging, they should be replaced. Buying a complete strut assembly is often a safer and easier alternative.
What's the difference between a strut and a shock?
A shock absorber is just a damper. A strut is a complete assembly that includes the damper (shock) and is a structural part of the suspension. On the Acura Integra, the part is technically a coil-over shock, but it is almost always sold and referred to as a strut.
