Cusco LSD 329 C Type RS Limited Slip Differential 1-Way 1.5-Way Front

The Cusco LSD 329 C is a Type RS limited slip differential engineered for high-performance street applications. This front differential utilizes Cusco's advanced spring-based technology to deliver superior traction and power distribution while maintaining smooth, quiet operation and exceptional durability.

Type RS Technology:

Unlike conventional cone-plate LSDs, the Type RS uses precision coil springs within the pressure rings to absorb initial torque. This innovative design provides 50-70% lower initial torque compared to traditional cone-plate designs, resulting in reduced drive friction, smoother engagement, and faster response. The spring technology keeps differential noise to a minimum while improving clutch plate longevity through reduced operating pressures.

Key Features:

• Dual configuration capability: 1-way and 1.5-way settings (adjustable with simple overhaul)
• 1-way operation specially suited for front-wheel-drive applications
• Spring-based pressure system for smooth, progressive torque application
• Reduced clutch plate wear and extended service life
• Lower friction design for improved efficiency and lap times
• Cusco's unique oil-through system for superior lubrication and cooling
• Chromoly steel casing and gears for enhanced durability
• Includes speedometer driven gear

Installation Notes:

Vehicles with open differentials require ten OE ring gear bolts (Honda P/N 90017-PYZ-000, sold separately). Speedometer indication will deviate approximately 3% after installation. Manual transmission applications only.

Performance Benefits:

The Type RS transfers power efficiently without slipping and responds quickly to throttle inputs. The low initial torque setting enables smooth cornering even when the LSD mechanism is not fully activated, while the coil spring design provides gentle and stable operation under all driving conditions. Proven in competition use including the All Japan Gymkhana Championship.
