Upper Rear Shock Bushings for Enhanced Suspension Performance

Ensure your rear suspension operates flawlessly and keeps your vehicle's shock absorbers in prime condition with Powerflex upper rear shock bushings. These essential components play a critical role in maintaining proper rear suspension geometry, making your vehicle's shock system work in perfect harmony. Even fresh from the factory, OEM rubber bushings are prone to failure and allow for unwanted deflection, resulting in undesirable consequences during various driving conditions.

Common issues arising from deflection in OEM bushings include:

• Rear-end clunking noises
• A sensation of "rear play"
• Uneven tire wear

Powerflex polyurethane rear trailing arm bushings are designed to be firmer than their OEM counterparts, significantly reducing deflection and its associated problems. By addressing these suspension angle changes, Powerflex bushings enhance your vehicle's performance and handling, especially when encountering road imperfections and while cornering. When paired with a proper alignment, they also contribute to extending tire life.

Why choose Powerflex:

1. Experience and Expertise: Powerflex is the leading suspension bushing manufacturer in Europe, trusted by countless enthusiasts. Their in-depth knowledge of polyurethane materials and state-of-the-art manufacturing techniques results in top-quality, precision-engineered bushings.
2. Durability: Powerflex performance polyurethane bushings outlast OEM rubber bushings, providing long-term reliability while improving your vehicle's performance and overall driving experience.
3. Ease of Installation: For a smooth installation process, we recommend using Powerflex Copper Grease PCG1. Periodic reapplication of the grease is advisable to maintain squeak-free bushings.
4. Versatility: Powerflex street bushings are ideal for everyday street-driven vehicles and those that occasionally participate in autocross or track events. If you need bushings for a dedicated track car, Powerflex Black Series bushings, featuring a 95A durometer polyurethane, are the ultimate choice, offering 25% greater stiffness compared to street bushings.

Rest easy with Powerflex's Lifetime Warranty, a testament to their commitment to product quality and customer satisfaction.

Elevate your vehicle's suspension performance with Powerflex upper rear shock bushings, the go-to choice for discerning drivers.

Want the best performance option in shock tower mounts? IRP has created their pillow-ball rear shock mounts for just this need. These rear shock mounts are designed for use on the track and racing. This set of mounts will help your rear shocks perform the best they can in all conditions. The advantage to using a mount with spherical bearing is that it allows the shock to freely move off axis without side loading the shock shaft like rubber or polyurethane mounts do. Side loading a shock increases stiction and wear which decreases its efficiency. Because these are mounts without an isolator (rubber or polyurethane) to dampen road noise and vibrations we do not recommend them for street cars.

The bearing sleeve and poly bushing are built to work with all stock style shocks such as Bilstein and H&R coilover and suspension kits.
