BMW E36/E46 M3/Z4M POLY DIFFERENTIAL COVER BUSHINGS - 33171134872

If you have ever been in your car and put it in first gear or take off from a dead stop, you may have heard and felt a loud “thud” coming from the trunk area of the car. This is a sure sign that your differential mounting bushings are worn out or failed. If you speak in BMW part numbers, then that's 33171134872. These mounts will help eliminate the slop and play in the differential mounting. This equates to better power transfer to the ground and a more secure feeling in the rear of your car under hard use.

Price is for a pair (2 units). Enough to do 1 car.

WHAT BMW CARS WILL THESE FIT?

• 1992-1999 E36 (NOT TI)
• 2001-2006 E46 M3
• 2007-2008 Z4 M

SHOULD I USE POLY OR DELRIN TO MOUNT MY DIFFERENTIAL?

We have this diff bushing available in 80a (soft poly), 95a (hard poly) and full-on Delrin. The stock E36 rear diff bushings are meant for comfort. It's meant to be quiet, so BMW allows for a little bit of movement for the sake of comfort. However, with its "floating" design it can fail under normal street use let alone any kind of performance driving. So we have the perfect solution. 80a soft poly is for that OEM + feel. That means you want a subtle upgrade for your street E46 without too much of a compromise in comfort, these are a happy medium. 80a are designed for the street enthusiast. 95a is great for dual purpose aggressive street and track applications. Delrin bushings are generally best for race applications only.

E36/E46/Z4 Rear Outer Control Arm Spherical Bearing Bushing (RTAB) - 328, M3, 325 - 33322228153/33326757885

Product Overview

These are the Garagistic Rear Lower Control Arm Bearings that replace the factory RTAB bushings found on your E36, E36, and Z4.  This set of rear trailing arm spherical bushings is on both sides of your rear control arms on your E36, E46, or Z4. 

The factory BMW E36 and E46 RTABs (Rear Trailing Arm Bushings) are meant for a very soft, quiet, and comfortable ride as possible. We design these with longevity and with abuse of grip and drifting in mind. We even made the bearings serviceable/replaceable without removing the housing from the trailing arm. Constructed with CNC'd 7075 Aluminum housing and Stainless steel spacers, these are built to last.

These have also been called toe bushing and the worn-out OEM rubber stock bushing (even when new) can result in toe changes indicated by a "floating" rear-end under hard track use. Keep in mind that BMW designed the original bushings with comfort in mind, not all-out performance.  If you have already run poly, and are ready for the ultimate solution to stiffen up a track or race car, then you are ready for these!

Please Note: These will transmit additional noise, vibration, and harshness, and are best for race applications only.

Replaces part numbers: 33322228153, 33326770786 and 33326757885

Note: Ask about our 5mm offset bearing side spacers that can provide extra toe alignment range for increased grip when you put the longer spacer on the outside.

Monoball Lower Spherical Rear Control Arm Bushing Set  - 328, M3, 325

Preorder Status: This is a preorder item and will ship in about 1 month!

Product Overview

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. 

These spherical bushings allow E36, Z3, E46, and Z4's lower rear control arms to actually articulate which will then lead to 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. 

These control arm spherical bearings replace the stock rubber bushings on the stock LOWER rear control arm, aka wishbone or camber arm. These will not fit with aftermarket adjustable camber arms. Our Spherical rear control arm bushings are meant to replace the OEM rubber parts in the lower rear control of your E36, E46 or Z4.

These replace part numbers: 33326770824, 33321092248, 33321138383

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.

NOTE: If you are looking for a complete set of both the lower and upper spherical bearings in the rear of your e36, e46, or z3, those can be found here: Click here for the complete set.
