The Powerflex BMW E21 Rear Axle Carrier Mount Bushing (Black Series) is a specialized component designed for high-performance applications, particularly suited to motorsport or track use. It replaces the standard rubber bushing in the rear axle carrier, providing enhanced durability and precision.

Key Characteristics:

High-Performance Polyurethane: Constructed from an extra-stiff polyurethane blend, the Black Series bushings are 25% stiffer than Powerflex's standard bushings, offering superior rigidity and control.
Race-Focused: Designed for maximum performance, these bushings reduce unwanted movement in the rear axle, improving suspension geometry and alignment under load. This leads to sharper handling and better grip in aggressive driving scenarios.
Durability: Unlike OEM rubber bushings, these polyurethane versions resist wear, deformation, and degradation from heat and fluid exposure, making them ideal for extreme conditions.
Precision Fit: Engineered to fit BMW E21 models, they provide a direct replacement, offering ease of installation and compatibility without the need for modifications.

This bushing is part of Powerflex’s most performance-oriented range and is ideal for drivers seeking to maximize the performance potential of their BMW E21 on the track or during spirited driving. Comfort is secondary to improved handling and precision with this upgrade.

Drive axle seal, located on the front differential. This seal works on both the left & right side axles. Due to regular exposure to dirt and debris, axle seals are a common failure item. An axle seal failure can cause fluid to leak from the differential housing, eventually causing it to run dry, which can result in front differential failure. Prevent a dangerous failure and costly repair bill by replacing your compromised axle seals with this genuine component directly from BMW. Replaces BMW p/n 31508860349, 31508743675, & 33107505601
