Our sealed Monoball Rear Trailing Arm Bushings (RTAB) are the best solution for completely eliminating deflection and unwanted toe changes on the rear of the E36, E46, and Z4. While rubber and urethane bushings flex during load, the toe can change widely giving you nervous and unpredictable handling. These RTABs have a solid aluminum housing with a high-quality sealed OE bearing. These bushings were developed from years of competition use in various racing and HPDE events. There is simply no better RTAB unless your racing class rules prohibit the use of mono or spherical bearings.

The rear trailing arm bushings take a lot of abuse from acclerating, braking and cornering. The stock rubber bushings are just not up to the task of keeping rear wheel alignment in spec for very long, especially if you have upgraded to stickier tires and a better suspension. The pliable rubber flexes and twists which slows down reaction time and leaves you with a car that feels nervous and 'tail happy'. Urethane helps to control the alignment but issues with fitment, maintenance, and longevity keep us from recommending urethane on anything but a street car. We also offer a Delrin RTAB for cars that must conform to certain racing class rules. These sealed spherical bearings are the best at controlling rear toe alignment.

Our aluminum RTABs are very well made - high grade aluminum alloy and steel CNC'd out of a billet by an ISO 9001 certified manufacturer, each component is either hardcoated or nickel plated. While multiple manufacturers offer two piece designs, our research showed that a one piece bushing is a better design featuring a sealed bearing to keep contaminants out extending the life of the bearing.

Rear trailing arm bushings serve the key purpose of keeping rear suspension triangulated and the vehicle moving where it's directed to. Though failure prone, even factory-fresh OEM rubber bushings allow for deflection, causing suspension geometry changes on hard launches, over bumps in the road, and during cornering. This deflection results in clunking in the rear end, a “rear steer” feeling, and uneven tire wear.

Powerflex polyurethane rear trailing arm bushings are firmer than OEM bushings, resulting in a reduction of deflection that causes these suspension angle changes, improving handling over bumps and with a proper alignment, extending tire wear.

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 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. 

This Product fits the following BMWs:

This tool makes it easy to press old rear trailing arm bushings (RTAB) out and install the new bushings. This RTAB tool is like a clamp with a puller that draws the bushing through the trailing arm. With the tool positioned on the trailing, simply turn the stud to pull the bushing out. This tool will save you time, money, and hassle on your RTAB DIY job.

Note: this tool works with bushings that are not an interference fit in the trailing arm. Interference bushings need to be compressed and then pressed into the arm. They can be identified by splits in the outer case.
