Cusco LSD 386 C Type RS Limited Slip Differential 1-Way Front for Honda Fit

The Cusco LSD 386 C is a Type RS Limited Slip Differential engineered specifically for Honda Fit models equipped with 5-speed or 6-speed manual transmissions. This front-position LSD is designed for enthusiasts seeking improved traction, handling dynamics, and cornering performance for both street and track applications.

Type RS Technology and Design:

The Type RS features Cusco's innovative coil spring design that delivers 50 to 70% lower initial torque compared to conventional cone plate LSDs. This advanced design provides smoother engagement, reduced friction, and better throttle response while maintaining exceptional locking capability when needed. The RS springs apply constant pressure against the clutch plates, ensuring minimal loss of initial torque over time and extending service intervals.

Key Features:

• Configurable 1-Way and 1.5-Way operation using dual-profile pressure rings without additional components
• High-strength cold-forged chromium-molybdenum gears for maximum durability and reliability
• Metal friction disc construction for stable performance across wide temperature ranges
• Cusco's exclusive radial groove-cut clutch plates for improved oil flow and cooling efficiency
• Oil Through System case design maximizes lubrication and heat dissipation
• Precision-polished pressure ring contact surfaces for even clutch plate engagement
• Reduced chattering and clutch plate wear compared to cone-type LSDs
• Proven competition-ready design used in All Japan Gymkhana Championship

1-Way Operation:

The 1-Way configuration is specially suited for front-wheel-drive vehicles like the Honda Fit. It activates under acceleration to maximize traction and power delivery, while acting as an open differential when the throttle is off. This setup is ideal for street driving and tarmac applications, providing improved lap times and cornering stability without introducing understeer during deceleration.

1.5-Way Operation:

The 1.5-Way setting activates under acceleration while providing partial engagement during deceleration with significantly less understeer than a 2-way LSD. This configuration is recommended for drivers who want more aggressive performance than a 1-way setup but prefer to avoid the handling characteristics of a full 2-way differential.

Designed for Honda Fit models with L15A or L15B engines and manual transmissions. Professional installation and the use of LSD-specific differential oil are recommended for optimal performance and longevity.
