Cusco LSD 137 B15 Type RS Limited Slip Differential 1.5 Way

The Cusco LSD 137 B15 is a Type RS limited slip differential engineered for high-performance street applications. This precision-manufactured LSD features Cusco's innovative inner-coil spring design that provides more consistent initial lock settings distributed evenly across friction plates compared to traditional limited slip differential systems.

Key Features:

• Type RS 1.5 way configuration with 45° and 15° cam angles
• Initial torque range of 10-12 kg/m for optimal street performance
• Inner-coil spring design maintains even pressure on friction plates
• Reduces chattering by providing consistent pressure across plate radius
• Oil-through design ensures positive pressurized flow of differential gear oil
• Prolongs friction plate life and prevents surface deformation
• Ideal for standing-start drag racing, autocross, and spirited street driving

The Type RS design allows for lower initial lock settings while maintaining responsive performance. The spring system keeps friction plates in constant even contact, minimizing chatter and extending component life. This LSD delivers maximum traction during acceleration and cornering by keeping both driven wheels firmly locked, preventing single-wheel spin and maximizing power delivery to the ground.
