OS Giken Super Lock LSD for Select 1988-2013 BMW M3, M5, M6, Z4 & 7-Series - BM237-HA
$1,950.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 1988-2013 BMW M3, M5, M6, Z4 M Coupe, and 740i/740iL/750iL models. The OS Giken Super Lock LSD (BM237-HA) is a high-performance 1.5-way mechanical limited-slip differential engineered to deliver progressive, predictable traction under any driving condition.
Unlike traditional clutch-type differentials, the Super Lock design utilizes a patented pressure ring and an increased number of friction plates. This allows for near 100% lock-up performance when torque is applied, without the chattering or harsh engagement typically found in race-spec units. For the enthusiast, this means superior corner-exit stability and more efficient power delivery to the ground.
- Increased Plate Capacity: Houses more friction plates than standard units for maximum torque transfer.
- Progressive Locking: Patented design ensures smooth transition from open to locked, reducing tire wear and drivetrain shock.
- Forged Steel Housing: High-strength construction ensures long-term durability in high-torque BMW applications.
- Maintenance-Friendly: Designed for reliability with high-quality internal components that resist heat and wear.
- MPN: BM237-HA
