Acura TSX Suspension Strut Replacement Guide (2004-2014)
Restore your TSX's sharp handling and smooth ride with the right replacement strut assemblies.
- Symptoms of failure include a bouncy ride, clunking noises over bumps, and visible fluid leaks on the strut body.
- For an OEM-like ride, KYB is the most recommended aftermarket brand for the TSX.
- Always replace struts in pairs (both front or both rear) and perform a wheel alignment afterward to ensure safety and prevent uneven tire wear.
- Choosing a complete strut assembly makes the replacement much easier and safer for a DIY mechanic.
Is Your TSX Ride Not What It Used to Be?
The Acura TSX, covering both the first generation (2004-2008) and the second generation (2009-2014), is celebrated for its blend of sport and luxury. A large part of that experience comes from its precise handling. Over many miles, the struts that provide this control can wear out. When this happens, you'll notice a significant change in how your car drives. It might feel bouncy, make noises over bumps, or not handle as sharply as it once did. 🎬 Watch: 5 symptoms of bad struts you should not ignore. Replacing worn struts is not just about comfort; it's about safety and restoring the performance you expect from your Acura.
Choosing the Right Aftermarket Strut Assembly
When shopping for new strut assemblies, you're choosing how your TSX will feel on the road. Aftermarket parts offer a range of options from budget-friendly replacements to those that restore original performance. Here's a breakdown of common brand tiers to help you decide.
OEM-Equivalent Brands: KYB
KYB is a highly respected brand, often considered an original equipment manufacturer (OEM) for many Japanese cars. For TSX owners who want to restore the original factory ride and handling, KYB is a top choice. Their Excel-G line is engineered to meet or exceed the performance of the original struts. Choosing KYB is the closest you can get to putting brand-new factory parts on your car without the high dealership price tag. Many owners report being very satisfied with the restored ride quality after installing KYB struts.

Monroe is one of the most well-known names in aftermarket suspension. Their OESpectrum line is a popular choice that provides a balance of comfort and control, designed to be a reliable replacement for the original struts. While generally considered a step below KYB in terms of matching the original TSX's specific feel, they are a dependable option that often comes at a more moderate price point.
Budget-Friendly Brands: FCS and PRT
For owners on a tighter budget, brands like FCS (FCS Strut) and PRT (Performance Ride Technology) offer an affordable way to replace failing struts. These are often sold as complete strut assemblies, which simplifies installation. While they will resolve the major symptoms of worn-out struts, like bounciness and noise, they may not provide the same level of handling performance or have the same longevity as higher-priced options. Owners who have used FCS struts report they get the job done and improve the ride over worn-out units, making them a practical choice for daily driving.

Known Issues, Recalls, and TSBs
While there have been no major recalls issued by the NHTSA specifically for the suspension struts on the 2004-2014 Acura TSX, there are related items to be aware of. A Technical Service Bulletin (TSB #05015) was issued for broken rear stabilizer links on some 2004-2005 models. Another TSB (DORE5C4S09) addressed a potential issue with the front upper ball joint housing. These are not strut issues but can cause similar clunking noises. It's wise to inspect these related components during a strut replacement.
Frequently Asked Questions (FAQ)
Do I need to replace all four struts at once?
It is highly recommended to replace struts in pairs, either both front or both rear. Replacing just one can cause an imbalance in handling and make the car feel unstable. If all four struts are original and have high mileage (over 90,000 miles), it's a good idea to replace all of them to fully restore your car's ride and handling.
What's the difference between a strut and a complete strut assembly?
A bare strut is just the shock absorber component. A complete strut assembly, or "quick strut," includes the strut, coil spring, strut mount, and boot all in one pre-assembled unit. For most DIY mechanics, a complete assembly is much safer and easier to install because you don't need a special spring compressor tool.
🎬 Watch this helpful guide on replacing your rear struts.Will a new aftermarket strut assembly change my car's ride height?
Standard replacement assemblies from brands like KYB, Monroe, FCS, and PRT are designed to restore the factory ride height. They are not lowering springs. If you want to lower your car, you would need to purchase specific lowering springs or a coilover kit.
What other parts should I inspect when replacing my struts?
When you're replacing the struts, it's a perfect time to inspect other suspension components. Check the sway bar end links, control arm bushings (especially the compliance bushings), and ball joints for wear, cracks, or looseness. These parts can also cause clunking noises and handling issues and are easier to access while the suspension is apart.
