Cusco LSD6C1J2 Type-MZ Rear 2-Way Limited Slip Differential for Toyota GR86 & Subaru BRZ

The Cusco LSD6C1J2 is a Type-MZ mechanical limited slip differential (LSD) designed for the rear axle of the 2022+ Toyota GR86 (ZN8) and Subaru BRZ (ZD8). Engineered for drivers who demand precise torque transfer and enhanced traction during both acceleration and deceleration, this unit is a direct-fit, high-performance upgrade over the factory open differential.

Type-MZ Differential Technology:
