Powerflex Front Control Arm Bushing Kit - E46 M3
Sharper steering and more precise handling with a lifetime warranty! Pre-installed into brackets. Replacement for BMW part #31122229857.
The best solution for solving the premature E46 M3 front bushing wear problem!
The Powerflex E46 M3 Front control arm bushing is one of our #1 selling products. The factory rubber bushing is a delicate piece that wears prematurely, creating sloppy steering, bad inner tire wear, and a jolting steering wheel under braking. Instead of replacing this bushing set with factory bushings every 40k miles, we suggest upgrading to the Powerflex urethane bushings for a long lasting upgrade that will increase steering response, reduce uneven tire wear, and reduce maintenance repairs.
These bushings add minimal, if any, NVH (Noise, Vibration, Harshness), and are recommended for street dedicated cars. One of the best features of these bushings is their 2 piece design. The bushings are made in 2 pieces so the rotation occurs between the urethane for a squeak free, easily lube-able bushing with a considerably increased lifespan. The inner bushing is grooved to hold the copper based lube (supplied with kit) for numerous years.
Powerflex has extensive experience in automotive suspension and chassis systems and has combined these skills with advanced polyurethane manufacturing techniques. Bushing durometer (stiffness) has been carefully selected for specific uses:
Street Performance for slightly more sport and precision in daily driving environments. Urethane material for less deflection, more precise handling, and better steering response but while retaining some comfort for street use. No track or very little autocross. If you attempt to use these in competitive driving you will quickly be outclassed by others with true race equipment.
A set includes 2 bushings PRE-INSTALLED into new brackets and lube for a complete kit. No other parts are necessary. If your E46 has more than 90k miles, we recommend taking a hard look at the front control arm's ball joints for wear as well. Any movement at these ball joints can produce bad tire wear and handling.
This kit comes with 66mm Powerflex bushings PRE-PRESSED into new 66mm housings for an easy installation you can do with minimal tools. Please allow one extra business day for us to press the bushings for you.
