Cusco LSD 565 L15 Type RS 1.5-Way Limited Slip Differential

The Cusco LSD 565 L15 is a Type RS limited-slip differential engineered for high-performance street and motorsport applications. Designed specifically for Mazda RX-7 FC3S models equipped with OEM viscous differentials, this rear differential utilizes Cusco's innovative coil spring pressure plate design to deliver superior traction and durability.

Key Features:

• Type RS 1.5-Way configuration optimized for balanced performance under acceleration with reduced understeer during deceleration
• Coil spring pressure plate design provides 50-70% lower initial torque compared to conventional cone plate LSDs for improved response and efficiency
• Advanced oil-through system enables superior lubrication and heat dissipation for extended service life
• Low-friction design minimizes power loss and reduces chattering for smoother operation
• Chromoly steel casing and gears manufactured in Japan to competition-grade specifications
• Consistent pressure distribution across friction plates reduces wear and extends maintenance intervals
• Proven in All Japan Gymkhana Championship competition use without mid-season overhaul

The Type RS design features precision-engineered springs that maintain even contact across friction plates, preventing deformation and prolonging component life. This differential efficiently transfers torque from the wheel with less grip to the wheel with more traction, maximizing power delivery during aggressive cornering and acceleration. Ideal for performance street driving, autocross, and road racing applications.
