Monoball Rear Control Arm Upper Inner Bushing Set - E36 E46 Z4

Overview

While OEM and aftermarket polyurethane works great, if you are looking for nothing less than the best, Monoball rear upper control arm bushings are a must-have. What many don't realize is that the E36, Z3, E46, and Z4's upper control arms actually need to articulate in order to maintain an even contact patch during any rough or changing surfaces. What Monoball bushings do best is preventing all side loading while also maintaining greater amounts of articulation than factory bushings.

Our Monoball upper control arm bushings are an absolute must for track cars and can be used on hardcore streetcars, however, we do want to warn you that these will increase the noise, vibration, and harshness of your ride so we recommend them most for dedicated track cars.

Save yourself alot of time by getting the tools to do this job with ease! No need to burn the bushings out in most cases, we use this kit for almost every bushing removal/installation: https://amzn.to/3ooRNdv

This replaces OEM part numbers: 33321092247 and 33321137571

Check your rulebook but these should be legal in SCCA IT, BMW CR Modified, and other racing classes. Recommended only for track use, not street use.
