Installation & Safety Notes

Ensure a professional-grade repair for your luxury sedan:

1. Side Selection: This part is interchangeable for the Left or Right side on the E38 chassis. We recommend replacing in pairs for balanced handling.
2. Torque Under Load: Crucial: Always tighten control arm bushing bolts while the vehicle is at normal ride height (on the ground) to prevent premature bushing failure.
3. Alignment: A professional 4-wheel alignment is mandatory after installation to restore factory handling specs and prevent tire wear.

Why Choose URO Premium?

While many aftermarket arms fail within a year due to inferior rubber, URO Premium focuses on "Problem Solver" engineering. By identifying why the original BMW parts fail, URO creates a replacement that is often superior to the OEM unit. It is the cost-effective way to maintain the legendary driving dynamics of your 7-Series without compromise.
