BMW Poly or Delrin Differential (diff) Bushing - E30, E36 318ti, Z3
BMW POLY OR DERLIN DIFFERENTIAL BUSHING- 33171135242
WHAT ARE BMW POLY/DELRIN DIFF BUSHINGS?
E30 bushings tend to be a tad overlooked. E30's do not age gracefully from a bushing perspective. Your old e30 diff bushing has seen a lot of wear and tear. The age of your E30 alone has taken it's toll on your differential bushings. The importance of bushings on your E30 is not to be understated; make sure that e30 diff is not moving all over the place under power. If your adding power to your e30 or running on an old, beat up and broken diff bushing (often letting you know its broken with a thump between shifts) then this is for you! This is our e30 Differential Bushing that replaces OEM part-number: 33171135242. Many motor-swap builds will also add a secondary diff mount, which can be found here; What the e30 secondary diff mounts will do is add an additional ear to prevent any diff damage. When selecting which diff mounts you'll be putting on your E30, E36, 318ti, or Z3, the question you'll need to answer is what is the primary goal of this bemmer? Is it track, autoX, street, or something in-between? You wouldn't be the first guy to track their daily! We try to cater to any and everyone when it comes to our bushings. In our YouTube video about BMW E30, E36 318ti, Z3 poly vs Delrin, we talk a little bit about which Garagistic diff bushings suit which application best. We stand by our products, all Garagistic bushings come with a lifetime warranty.

We have them in 80a poly , 95a poly and delrin! 80a e30 diff bushing is meant for that OEM + feel. That means you want a subtle upgrade for your street e30 without to 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.
