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

The Cusco Type-RS LSD is a high-performance limited slip differential designed for the rear axle of 2021+ Toyota GR Yaris and 2023+ GR Corolla models. This race-proven differential enhances traction by reducing individual wheel spin and transferring power to the wheel with the most grip, providing superior control during high-speed cornering and aggressive driving.

Key Features:

• D-size construction with low initial torque design (2-4 kg-m) for responsive handling and extended durability
• Adjustable configuration: 1-Way (45/0 deg) and 1.5-Way (55/20 deg) settings changeable during overhaul with no additional parts required
• Unique RS coil spring design that absorbs initial torque for gentler engagement compared to cone plate LSDs
• 50-70% lower initial torque versus conventional cone plate type LSDs, reducing drivetrain power loss
• Significantly reduced chattering noise compared to traditional limited slip differentials
• Proprietary Oil Through System with chrome molybdenum steel casings for enhanced lubrication and cooling
• Precision forged internal side gears and pinion gears capable of handling high horsepower applications
• Radially grooved MZ clutch plates for instant oil movement and improved efficiency
• Lower friction design provides better throttle response and more direct power delivery

The Type-RS has been proven in competition use in the All Japan Gymkhana Championship, with teams completing entire seasons without requiring a single overhaul. Ideal for performance street vehicles and underpowered applications where minimizing power loss is critical. Compatible with 6-speed manual transmission equipped vehicles.
