Cusco LSD 380 R Type-RS Pro Adjustable Limited Slip Differential

The Cusco LSD 380 R is a high-performance Type-RS limited slip differential featuring Pro-Adjustable functionality for enhanced customization. Engineered specifically for Honda S2000 AP1 applications, this mechanical LSD utilizes an innovative center coil spring-loaded design that delivers superior traction and control for street and competition driving.

Type-RS Coil Spring Technology:

The Type-RS distinguishes itself from conventional cone plate LSDs through its precision coil spring design. The RS springs are positioned inside the pressure rings, where they absorb initial torque and provide gentle, progressive engagement. This results in 50-70% lower initial torque compared to traditional cone plate designs, reducing drive friction while improving response and efficiency.

Key Features:

• Pro-Adjustable cam profiles allow switching between multiple way configurations without purchasing additional parts
• Lower initial torque setting enables smooth operation during normal driving conditions
• Reduced clutch plate pressure extends durability and minimizes chatter
• Exclusive Cusco Oil Through System ensures optimal lubrication to all internal components
• Chromoly steel construction with precision-machined gears for maximum strength
• Radially-cut clutch plate grooves enable instant oil movement for improved efficiency
• Customizable spring configuration allows personal tuning preferences
• Competition-proven design with reduced maintenance requirements

Performance Benefits:

The low initial torque design translates to measurably lower power loss through the drivetrain, resulting in improved lap times even in mildly tuned vehicles. The coil spring design prevents clutch plates from sticking together like conventional cone plate LSDs, significantly reducing wear and deterioration. The reduced pressure on clutch plates also allows for extended oil change intervals compared to higher-pressure differential designs.

During aggressive cornering and track driving, the Type-RS efficiently distributes torque from the wheel with less grip to the wheel with more traction, eliminating the power loss associated with standard open differentials. The quick engagement characteristics make this differential ideal for autocross, drag racing, drifting, and spirited street driving.
