Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components. 

Powerflex street bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Need bushings for a dedicated track car? Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure with Powerflex performance polyurethane control arm bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

Control arm bushings play a key role in connecting the wheels to the chassis of the vehicle. Tasked with keeping suspension geometry in check while absorbing noise, vibration, and harshness (NVH) factory rubber bushings were engineered to provide a balance of comfort and control. As a factory bushing ages, it becomes brittle and begins to harden. When this happens the bushing will actually shrink and allow excess play in the suspension joint. This is typically felt by a sudden jerk forward after the car comes to a stop and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushing with a full polyurethane unit or using a bushing insert, this play is eliminated since the suspension joint is being supported by a much stiffer material that will not harden or shrink over time. Additionally, the inherent stiffness of the urethane material translates body forces much more directly. This means steering inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver.

Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This in turn reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.

Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.

This part fits the following BMWs:

All 1999-2006 E46
All 2002-2008 E85 Z4

This suspension package of Bilstein Sport shocks and H&R Sport springs will lower the ride height and firm up the suspension to provide less bodyroll and better handling. This E24 and E28 suspension package is firm but not harsh and can be used on daily-driven street cars as well as backroad and weekend corner carvers.

H&R Sport springs lower the ride height by 1.25" and stiffens the spring rate. Both combine to lower the car's center of gravity and reduce the amount of bodyroll in corners. The springs are progressive rate so their initial stiffness is actually very compliant and it becomes stiffer as the spring is compressed. This is great for street cars that see bumps and potholes where suspension compliance is key. Overall, they are about 40% stiffer than the stock original springs. The ride quality is a little stiffer than a stock E28 M5.

We use Bilstein Sport shocks as the dampers and they feature Bilstein's patented and innovative valving system. With this system, small bumps and impacts are absorbed as they should be. But the shocks stiffen for cornering and other suspension motions. It's the best of both worlds as the shock self-adjusts based on suspension motion. These fit with the stock strut and shock mounts, making for an easy and clean install.

Although this suspension is listed for the E28 M5 and E24 M6, the original rear self-leveling system must be disabled or removed.
 

Parts list:

• 1 set - H&R Sport Springs (50428)
• 1 pair - Bilstein Front Sport struts (P36-0243 / 34-181546)
• 1 pair - Bilstein Rear Sport Shocks (B46-0607 / 24-006071)

This item fits the following BMWs:
1982-1988 E28 BMW 528e 533i 535i 535is M5
1982-1989 E24 BMW 633csi 635csi M6

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.
