Cusco LSD-1C8-L15 Type-RS Rear Limited Slip Differential 1.5 Way

The Cusco LSD-1C8-L15 Type-RS is a high-performance rear limited slip differential designed for the Toyota GR Yaris and GR Corolla. This racing-grade LSD features Cusco's innovative coil spring design that delivers lower initial torque for smoother engagement and quicker response compared to traditional cone plate differentials.

Key Features:

• Type-RS design with inner-coil spring system for consistent, even pressure distribution across friction plates
• 1.5-way configuration (activates under acceleration with partial engagement during deceleration) that can be converted to 2-way without additional parts
• Dual cam ramp pressure plates for tuning flexibility
• Adjustable initial torque settings by adding or removing coil springs
• Initial torque range: 2-4 kg (4.4-8.8 lbs)
• Oil-through design ensures positive pressurized flow of differential gear oil throughout the system
• Lower friction and reduced chattering compared to conventional LSD designs
• Minimized clutch plate wear and extended service life
• D-size differential housing

Performance Benefits:

• Immediate actuation response from initial lock to maximum preset lock rate
• Ideal for standing-start drag racing, autocross, and short track applications
• Lower maintenance requirements than traditional racing differentials
• Proven competition-tested in All Japan Gymkhana Championship
• Smooth turning characteristics even when LSD mechanism is not fully activated

The Type-RS is perfectly suited for drivers who prefer lower-powered compact cars in competition use, prioritize smooth response, and want a racing differential with reduced maintenance needs. Professional installation recommended; requires differential bearing replacement, proper shimming, and backlash adjustment.

Specifications: Initial Torque 2-4 kg, Repair Kit #25, SST #02 required for service
