Our BimmerWorld Precision Front Upper Control Arm Bearing Kit was designed because of the huge amount of suspension load that the front upper control arm, or thrust arm, takes in an E82, E90, E91, E92, and E93 car under braking. In street cars, the rubber bushings in both the M3, non-M, and Z4 cars are big and soft with an open design to allow the joint to rotate in multiple axes, which is required when turning the steering wheel through its range of motion. Unfortunately, this means the bushing is compressing and then releasing and causing the tire to skip across the pavement under braking - a condition worsened once ABS is engaged. Factor in worn rubber parts and the problem compounds itself.

Our Precision Front Upper Control Arm Bearing Kit is the slam dunk solution for this problem. Utilizing a fully-sealed bearing, similar to the factory monoball bushings in other suspension points, gives full multi-axis rotation. Since this is a true OE-quality bearing and fully sealed, this part is perfectly at home even on a performance street car and the durability and performance is perfect even in the extremes of a 24-Hour endurance race car. Adding these parts to your street or track car will make a noticeable improvement in braking and turn-entry grip.

Fits all 2WD E82, E82 1M, E90/E91/E92/E93, E9X M3, and E89 Z4 models. Replaces the inner rubber bushing on the upper control arm, aka tension strut or thrust arm (the one with all of the bends in it). The M3 lower control arm has a similar sealed bearing and can also be used on non-M cars for an upgrade.

European-manufactured OEM bearing insert. Kit designed, machined, and assembled in USA.
