BMW E21 / 2002 LSD Diff 3.91 Pre-Built BMW E21 / 2002 LSD Diff 3.91 Pre-Built

BMW E21 / 2002 3.91 1.5-Way 40% LSD.

This is a pre-built differential to suit E21 and 2002. It is an E21 diff, so fitment into the 2002 may require the correct back plate and may also require output shaft drilling or spacers.

This diff is original in the pinion end, but in the rear end it has: new bearings, new seals, new bolts, machined side covers for bearing replacement, new o-rings, new washers, near-new clutches, fully rebuilt E36 LSD, modified 1.5-Way 25/40 ramps. The original pinion bearings and pinion seal are retained to save on cost.

All Pre-Built diffs are sold on an exchange basis. Your new diff is swapped directly for your existing diff of the same type.
