Rear Camber Arm Outer Bushings (RTAB), Powerflex - E36, E46, Z4

Outer bushing for the lower camber arm (aka wishbone) on E36, E46, and Z4 models.

These bushings are the pivot point between the lower control arm and the rear trailing arm on many E36, E46, X3 and Z4 BMWs. The stock rubber bushings are known to wear out and eventually fail, causing the rear suspension of your BMW to feel less stable during cornering. These upgraded Powerflex bushings are made of high quality polyurethane and solve this problem for good. Replace your worn or damaged lower outer bushing with urethane for improved rear-end stability.

Note: Powerflex copper-based grease is supplied with every bushing set, and they will rarely need re-lubing due to the unique design features built into the material to hold the lubricant.

Lifetime warranty!

May also be used to replace the upper ball joint (33306852895 or 33326775551) but would not be our recommendation. Our preference is to use the upper ball joint on the top and bottom. The upper ball joint is an OEM upgrade over the original rubber bushing. The urethane bushings are our second choice.
