Cusco LSD 985 F2 Type RS Limited Slip Differential 2-Way

The Cusco LSD 985 F2 is a Type RS Limited Slip Differential designed as a direct replacement rear differential for the Lexus IS-F (USE20 chassis, 2008-2014 with 2UR-GSE 5.0L V8 engine). This high-performance LSD features interchangeable 1-way and 2-way operation, arriving pre-set in 2-way configuration for optimal rear-wheel-drive performance.

Key Features:

• Coil spring pressure system provides lower initial torque (50-70% less than conventional cone plate LSDs) for smoother engagement and better throttle response
• High-tensile forged chromium-molybdenum steel case, gears, and components ensure extreme durability under high horsepower applications
• Interchangeable cam design allows switching between 1-way and 2-way operation without additional parts
• Oil Through System case design maximizes cooling and lubrication efficiency
• Radially-grooved clutch plates enable instant oil movement for improved efficiency and extended service life
• Adjustable initial torque by adding or removing specialized RS coil springs
• Minimal clutch chatter and reduced plate wear compared to cone-type LSDs
• Proven competition-grade performance from All Japan Gymkhana Championship use

The 2-way configuration activates during both acceleration and deceleration, making it ideal for aggressive driving, drifting, and track use. The Type RS design emphasizes smooth operation with progressive locking characteristics, making it suitable for both street and competition applications.
