Powerflex Rear Trailing Arm Bushings - Mk7 VW | (w/ IRS) | PFR85-816

These urethane performance bushings replace the stock rubber rear trailing arm bushings on the Mk7 Golf with IRS. With the stock rubber bushings, the rear trailing arm has a lot of flex and deflection, which makes the car feel unstable and lacking 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 (applies to Street bushings only, see warranty page for complete info).

Sold as a pair for the trailing arm (see diagram).

Powerflex polyurethane bushings are designed to decrease the amount of deflection in your car's suspension which improves handling, driver feedback, and tire wear. Powerflex uses their own premium polyurethane formulation to provide minimal NVH (noise, vibration, harshness) and increased longevity over stock rubber bushings.

Bushings are produced in one of three durometers – Yellow (70A, approximately 25% stiffer than stock), Purple (80A, approximately 30% stiffer than stock), and Black (95A, approximately 80% stiffer than stock). Unlike other brands using only one urethane grade for all applications, Powerflex design engineers choose the correct hardness to allow for the specific movement or rigidity required for each location while minimizing unwanted NVH.

Powerflex urethane hardness is standardized per fitment and location. This takes out the guess work, so when you choose Street, you know our design engineers have selected the optimal polyurethane hardness for your specific application. Select parts are also available in an optional stiffer urethane (Black Series) for track and autocross performance where NVH is less important.
