Transform your open differential into a real clutch-type LSD
Upgrade your BMW E90, E92, E87, E82 or E60 with a high-performance 188L Limited Slip Differential (LSD), designed for newer-generation BMW models equipped with low-friction differentials. This upgrade transforms your factory open differential into a true traction system, eliminating one-wheel spin and delivering improved grip, stability and control for street, drift and performance driving.
This drop-in unit replaces your factory open carrier with a fully forged, clutch-type differential core that delivers maximum traction and race-grade reliability — while staying civil on the street. It uniquely combines up to 100% lock under full throttle with zero noise or chatter in tight turns, striking the ideal balance between performance and comfort.
