Cusco LSD RS 1.5-Way(1.5&2) Toyota Supra (MA70) Mark II/Chaser (JZX100 w/Torsen Diff)

The Cusco RS 1.5-way Limited Slip Differential is built with a unique clutch pack design that allows for a variable lock-up ratio, offering 1.5-way engagement. This means it provides strong locking under acceleration and a controlled amount of lock-up during deceleration, which helps stabilize the rear end during cornering. This unit is specifically designed for the Toyota Supra MA70 and the Mark II/Chaser JZX100 models that came equipped with a Torsen differential, ensuring a direct fit and optimal performance for these enthusiast vehicles.

Cusco's RS series LSD utilizes a combination of clutch plates and ramp angles to achieve its 1.5-way behavior. Under acceleration, it engages fully to distribute power to both rear wheels, maximizing traction out of corners. During deceleration, the 1.5-way design offers a partial lock-up, which helps to reduce understeer and improve stability. This makes a notable difference in how the car handles during spirited driving or track use. The internal components are well-made to handle the stresses of performance driving, providing a solid upgrade over a factory open or Torsen differential.

Installation of a limited slip differential is a complex job that requires specialized knowledge and tools. It's highly recommended to have this unit installed by a professional mechanic experienced with drivetrain components. Proper setup and break-in procedures are crucial for the longevity and performance of the LSD. Ensure you consult the manufacturer's installation manual for detailed instructions regarding setup, break-in, and fluid recommendations to get the most out of your new Cusco LSD.
