Cusco LSD-1C8-L2 Type-RS Limited Slip Differential - 1.5/2-Way Rear

The Cusco Type-RS Limited Slip Differential represents a breakthrough in mechanical LSD technology, featuring an innovative coil spring design that delivers smooth, progressive locking characteristics ideal for high-performance street and track applications. Unlike traditional cone plate LSDs, the Type-RS utilizes RS springs positioned between pressure rings to create lower initial torque with superior throttle response and enhanced driver control.

Key Features:

• Coil spring design provides 50-70% lower initial torque compared to cone plate types for smoother operation and reduced drivetrain resistance
• Dual-mode adjustability: Pre-set to 1.5-way, easily convertible to 2-way by reversing internal cam profiles without additional parts
• High-tensile forged chromium-molybdenum steel case, gears, and components for extreme durability under high horsepower
• Oil Through System case design with large oil windows maximizes cooling and lubrication efficiency
• Radially-cut clutch plate grooves enable instant oil movement for improved efficiency and longevity
• Six clutch discs per side with D-size construction and 12 RS springs standard
• Adjustable initial torque (2-4 kg/m) by adding or removing RS springs
• Cam angles: 2-way 55°/55° or 1.5-way 55°/20°
• Precision-polished pressure ring surfaces ensure even contact and minimal chatter

Technical Advantages: The RS spring system applies constant, even pressure across friction plates, resulting in minimal initial torque loss over time and extended service life. The low-friction design reduces clutch plate wear significantly compared to high initial torque differentials, making it ideal for street-driven performance vehicles that demand responsive mid-corner adjustability and smooth daily drivability.

Application Note: The 1.5-way configuration is recommended for most street and road racing applications, providing excellent acceleration lock-up with reduced understeer characteristics. The 2-way setting is preferred for drift and rally competition where locking on deceleration enhances vehicle control and aggressive driving dynamics.
