The Rogue Engineering Rear OFFSET Lower Control Arm Bearings replace the factory 33-32-6-775-551 bushings with serviceable, precision, spherical bearings. The climate in the Northeast where we are can be rough on suspension components, so we design these with longevity in mind. Constructed with CNC'd 303 stainless steel housing and spacers, these are built to last.
Why do I need the OFFSET 551 bushing?
Reason # 1: The 551 offset bushing is offset by a total of 5mm from center. Combined with a matching pair, the upper and lower control arms can be 10mm closer together at the outer knuckle. This changes the angle of the arms to be more parallel and gives a more controlled movement when the knuckle travels through it's range.
Reason # 2: For those having rear tire fitment issues, bringing the top of the rear knuckles in by 5mm can bring the top of the rear knuckle inwards, giving more negative camber. When used with adjustable rear arms, you can increase it even more.
Removing that wobbling bushing
On the rear of the E36 and E46 platform, a commonly neglected bushing is the outer control arm bushings (highlighted in blue in the above diagram). By replacing them with the Rogue Engineering versions, you reduce suspension deflection and unwanted flex. The precision spherical bearing is designed to be easily removed and serviced if ever a replacement bearing is required, so maintenance is even simpler with these installed.
Rogue Engineering Rear Outer Control Arm Bearing Features
- Housing and spacers are CNC'd from 303 stainless steel to prevent corrosion
- Spherical bearing is easy to service
- Legal for all BMW CCA Prepare or Mod race classes, SCCA IT classes, and all NASA GTS classes.
- Replaces factory bushing P/N 33-32-6-775-551
- Sold as a PAIR. Purchase TWO pairs to move the upper and lower positions closest together.
Future Serviceability
While there is no such things as a "forever bushing", serviceability of the Rogue Engineering component is much easier than the factory unit. Because of the precision CNC'd construction of the Rogue Engineering component, removal and installation of the spherical bearing is much easier that the factory version. Replacing the spherical bearing requires the removal of the circlip, tapping out and replacing the bearing, and reinstalling the circlip. A bearing replacement should take no more than 10 minutes with a qualified mechanic.
This product fits the following vehicles:
- All E36 including M3, except ti
- All E46 including M3
- All E85 including MZ4
- All E89
Note that some vehicles (such as E36 M3 and E46 M3) utilize factory P/N 33-32-6-775-551 on the upper and lower outer control arm bushings. For these applications two pairs (4 bushings) can be used. Check your application to confirm that your application is compatible.
As an added upgrade, be sure to consider our replacement Adjustable Rear Control Arms for the ultimate in strength and suspension performance.
