Saturn Relay 2005-2007 New Aftermarket Suspension Shock Absorber Guide
Restore your minivan's ride quality and stability by choosing the right replacement shocks.
- Bad shocks cause a bouncy ride, nose-diving when braking, and can lead to uneven tire wear.
- For this vehicle, the rear uses shock absorbers, while the front uses strut assemblies.
- KYB and Monroe OESpectrum are recommended for restoring original ride quality; FCS and PRT are good budget options.
- Always replace rear shocks in pairs to maintain vehicle stability; a wheel alignment is not needed for this job.
Is Your Saturn Relay's Ride Getting Bouncy?
The shock absorbers on your 2005-2007 Saturn Relay are designed to keep your ride smooth and controlled. When they wear out, the signs are often hard to ignore. Because the Relay shares its platform with the Chevrolet Uplander, Buick Terraza, and Pontiac Montana SV6, these symptoms are common across all of these GM minivans.
Symptoms of Failing Shocks:
- Bouncy or Floating Ride: The most common symptom. Your van may feel like it's floating over bumps and will continue to bounce up and down long after the bump is gone.
- Nose-Diving and Squatting: When you hit the brakes, does the front of the van dip down excessively? Or does the rear end squat down when you accelerate? This is a classic sign of worn shocks.
- Unusual Noises: You might hear a clunking or knocking sound coming from the rear of the vehicle, especially over bumps. This can happen when internal components of the shock have failed.
- Uneven Tire Wear: When shocks can't keep the tires planted firmly on the road, the tires can bounce and lead to cupping—a pattern of scalloped dips in the tread.
A Note on Front vs. Rear Suspension
On the 2005-2007 Saturn Relay, the front suspension uses a MacPherson strut assembly (a combined shock and spring unit), while the rear uses a separate shock absorber and spring. This guide focuses on the standalone rear shock absorbers, which are a common replacement item.
Choosing the Right Aftermarket Shocks for Your Relay
When shopping for new aftermarket shocks, you'll find several brands available. They generally fall into different quality and price tiers. Since there are no major known defects with the original factory shocks, choosing an aftermarket part is a safe and cost-effective decision.
Premium Brands: KYB & Monroe
These brands are engineered to restore or even improve upon the original ride quality. They are the best choice if you plan to keep your Relay for a long time and want the best performance.
- KYB: Often considered a benchmark for OEM-quality replacements. The KYB Excel-G line is specifically designed to restore the vehicle's original handling and control characteristics. They are a trusted choice for bringing your Relay's suspension back to factory spec.
- Monroe: The Monroe OESpectrum line is another premium option designed to provide a smooth, controlled ride that meets or exceeds factory performance. They are engineered to filter out noise and vibration, making them a great choice for a comfortable family hauler.
Economy Brands: FCS & PRT
If you're on a tighter budget or need a quick fix, these brands offer a functional and affordable solution. They will get the job done but may not offer the same longevity or refined ride quality as premium options.
- FCS Struts: A popular budget-friendly brand. FCS shocks will solve the immediate problem of worn-out shocks but may have a softer feel and shorter lifespan compared to KYB or Monroe.
- PRT (Performance Ride Technology): Another value-oriented brand that provides a basic, functional replacement to get your Relay safely back on the road at a low cost.

|---|---|
| New Aftermarket Shocks (Pair) | $50 - $160 |
| Shop Labor | $100 - $200 |
| Total Professional Installation | $150 - $360 |
Frequently Asked Questions
Do I need a wheel alignment after replacing rear shocks?
No. Replacing the rear shock absorbers on a 2005-2007 Saturn Relay does not affect the vehicle's alignment angles. A wheel alignment is typically only needed after replacing front struts or other steering components.
Is replacing the rear shocks a good DIY job?
Yes, for many people with basic tools, this is a very manageable DIY task. The rear shocks are typically held in by just two bolts—one at the top and one at the bottom. The biggest challenge is often just getting enough leverage to loosen rusted bolts.
What's the difference between a shock and a strut?
Your Relay has both. A shock absorber is a standalone damping component, like on the rear of your van. A strut is a structural part of the suspension that combines the shock and spring into one assembly and supports the vehicle's weight, which is what your Relay has on the front.
Are there any recalls for the Saturn Relay's shocks?
No. As of early 2026, there are no specific NHTSA recalls or Technical Service Bulletins (TSBs) for the suspension shock absorbers on the 2005-2007 Saturn Relay. Any failure is considered a result of normal wear and tear.
