Cusco LSD 3A9 C Type RS Front Limited Slip Differential 1-Way Honda Civic Type R

The Cusco LSD 3A9 C is a Type RS Front Limited Slip Differential engineered specifically for Honda Civic Type R models (FK8/FL5). This high-performance mechanical LSD features a 1-way configuration with dual cam angle capability, allowing conversion to 1.5-way setup without additional components.

Key Features:

• 1-Way 35° configuration with ability to convert to 1.5-Way 50°-15° by rotating center spline
• Initial torque preset: 3-5 kgf-m with 6 standard RS coil springs (expandable up to 12 springs)
• Coil spring design provides gentler, more progressive engagement compared to cone plate LSDs
• High-tensile chrome molybdenum steel housing and gears for extreme durability
• Large oil windows with Cusco's original groove cut technology on clutch plates
• Oil Through System ensures optimal lubrication and cooling throughout the differential
• Dual ramp angle pressure rings allow fine-tuning of locking characteristics
• Lower friction design reduces clutch plate wear and extends service intervals

The Type RS utilizes an innovative inner-coil spring design that applies constant, even pressure to the friction plates, resulting in more consistent performance and minimal torque loss over time. This design delivers superior throttle response and mid-corner control while reducing chatter and power loss compared to traditional cone spring differentials. Ideal for front-wheel-drive applications including street performance, track use, drag racing, and drifting.
