Rogue Engineering, this rear differential is a must for hard-driven E36 cars. During even short track sessions, the limited slip clutches and gears in your differential heat up the fluid to a critical level - this is the reason for the fluid often seen seeping out of the vent hole after hard use. This replacement cover holds 1.5 additional quarts of fluid and has extensive cooling fins to keep your differential cool to avoid costly failure.

I also have all the bolts,ect. The cover is brand new never installed. Im asking $400 plus shippingSOLD

Where in CA are you?

that's only $19 cheaper than I can get it at Turner. I'll buy it if your price drops quite a bit.

your right your price $100 haha tell you what if it doesnt sell next week ill entertain your idea
