Need a set of asymmetrical ramps for your 188mm BMW differential? We have them!
This ramp set is original from ZF (the manufacturer for BMW differentials) and drops into BMW differential with no modification required. The asymmetrical 50/65 setup is optimal for any performance build. Unlike competitors that offer custom cut ramps which fail due to the weakness left behind after machining, these are unmodifed and reliable. Stack height is maintained the same as the stock 45/45 pressure assembly so no special tolerancing is necessary.
