More cooling, fluid capacity and longevity!

From our differential building and racing experience, a cool running diff is a crucial part of a vehicle that sees high performance use. M3s and 1Ms shouldn't have all the fun: We are now offering our awesome custom made differential cover for your 135 and 335!

BMW will tell you that in the stock configuration, gear oil is a "life-time" fill, sadly that nonsense helps them skirt costs and leave the same gear oil in your car forever. This frustration is compounded by the fact that the OE diff cover doesn't even have drain and fill plugs so the end user can do a swap themselves!

Under hard use, LSDs equipped diffs can run very hot, even the OS Giken diffs have been known to heat gear oil to extreme temps under track use. Our finned cover is stronger, and offers much better heat dissipation that these cars need when going to the track.

Now you can change fluid any time you like for longevity and protect your expensive aftermarket differential. A worthy upgrade for your E82, E87 E90, E92, E93 LSD setup.

Each VAC Finned Diff Cover Features:

Increase oil capacity
Increase cooling capacity via heat-dissipating fins
Machined from a single billet of 6061-T6 aluminum
Drain and fill holes are machined for AN -8 o-ring plugs allowing for easy conversion to a diff oil-cooler setup
Integral vent for street cars; pre-machined provision for external catch-can setup for racecars
Pre-machined provision for differential oil temperature sensor
OE Quality 10.9 grade flanged hex head hardware provided
Improved Strength over Cast Cover
No adverse effects on ride quality or noise
Excellent ground clearance
As always, Made in the USA in house at VAC!
