Uniball rear trailing arm bushings BMW E36 / E46 / Z4 – rear trailing arm bushing upgrade

Uniball rear trailing arm bushings for BMW E36, E46 and Z4 (E85/E86) are an ideal upgrade for more precise rear axle guidance and elimination of unwanted movements during driving and drifting. This rear trailing arm bushing kit replaces the serial rubber bushings, which wear out quickly and cause geometry changes.

By using a uniball solution, you will significantly improve stability, chassis response, and control over the car – especially during aggressive driving, drifting, or trackday use.

The aluminum housings are CNC machined and anodized for maximum strength and durability. The monoball (spherical joint) itself eliminates deformation typical of OEM bushings, thereby ensuring consistent rear axle behavior.

Main advantages:
- more precise rear axle geometry
- elimination of deformation compared to OEM bushings
- ideal for drift, trackday and performance builds
- longer lifespan than the serial solution
- easier service due to design

Technical solution:
- CNC machined aluminum housings (anodized)
- uniball / monoball mounting
