Powerflex Front Strut Top Mount Bushing (10mm Lower) - MK4 VW | MK1 TT | PFF85-431

The 10mm Lowering part replaces 1J0412331C and has been designed to give an extra 10mm of lowering when fitted as it allows the strut to sit higher into the body of the top mount. These new top mounts ship complete with new top cap spacers, made using Powerflex Black material.

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.
