Powerflex Porsche 911, 996 / 997 Rear Upper Control Arm Outer Bushings 19.5 mm

Porsche 911, 996 / 997 Rear Upper Control Arm Outer Bushings 19.5 mm

This part fits 19.5 mm arms.These urethane performance bushings replace the stock rear upper outer control arm bushings on the Porsche 996 & 997 model 911. With the stock rubber bushings, the rear control arms have a lot of flex and deflection, which makes the car feel unstable and lack precision, especially during hard cornering. These urethane bushings are stiffer than stock rubber and will not deflect as much. This helps keep the alignment in check with less variation. A limited lifetime warranty means you'll likely never have to pay for another bushing ever again.Unlike other urethane bushings using only one or two urethane grades, Powerflex design engineers choose the correct hardness to allow for the specific movement or rigidity required for each component while minimizing unwanted NVH. Bushings are typically produced in one of three grades �� Yellow (70-80A, approximately 25% stiffer than stock), Purple (80-90A, approximately 30% stiffer than stock), and Black (90-95A, approximately 80% stiffer than stock). This bushing set is offered in Black only as that is the desired durometer necessary for this installation location.Sold as a set of four for the 996 and 997 model 911 rear upper control arms (see diagram). Replaces Porsche part #99633104703.Note: most 911 models use a 22mm wide rear control arm but a 19.5mm arm was also used. We advise checking the width of the control arm and then ordering the appropriate bushings.

Why Powerflex?
Because Safety Matters

Powerflex bushings are engineered for each individual application. Our premium bushings improve performance, increase tire life, and enhance safety. Plus, every Powerflex part comes with a Lifetime Warranty, so you never have to worry about replacement parts again. That includes our growing line of jack pad adapters which allow you to safely and securely lift your vehicle for anything from major work to a quick tire rotation.

Our proprietary blended urethanes last longer than run-of-the-mill polyurethane you might find elsewhere. Powerflex polyurethane is formulated specifically for automotive applications that have unique environmental factors like vibration, oil, and varying load-types, yet our Street options display minimal NVH if any at all, even in instances such as these bushings, where our engineers have opted for Black Series bushings as the ideal option for street use.
