Product Details
This Whiteline Front Lower Radius Arm Bushing (Standard Repl.) fits the 2013 BMW 135is 1 Series. Order it as part number W83391. The kit contains 2 bushings, 2 tubes, an install guide, and grease. It goes on the front of the vehicle.
When a radius arm bushing fails, the wheel is no longer held where it should be under braking and over bumps. This is a like-for-like replacement: it restores the original pivot behavior and ride comfort rather than changing them.
Installation is rated moderate, with about 1.5 hours of work listed. Get the car aligned once it is back on the ground. Other Whiteline parts we list for the 135is 1 Series: Rear Sway Bar Link, Adjustable Front Sway Bar Link, and Rear Lower Trailing Arm Bushing.
