Cusco LSD 194 C Type RS Limited Slip Differential

The Cusco LSD 194 C Type RS is a high-performance, center coil-loaded mechanical limited slip differential engineered for drivers who demand improved traction, sharper throttle response, and race-proven durability. Designed and manufactured in Japan, the Type RS LSD represents Cusco's commitment to precision drivetrain engineering for both spirited street driving and competitive motorsport applications.

Type RS Technology:

The Type RS design applies activation pressure in the same direction as the initial torque through the use of a precision coil spring. This results in a lower initial torque setting compared to the standard MZ model, allowing for smoother and quicker clutch plate engagement — transitioning seamlessly from a non-operational to a fully functioning state. The low initial torque characteristic also enables smooth cornering even when the LSD mechanism is not actively engaged.

Key Features:

• Center Coil Spring Design: Precision springs set in the pressure plate ensure steady, consistent coil movement and gentle, stable LSD operation
• Low Initial Torque: Initial torque is 50–70% lower compared to conventional cone plate type LSDs, reducing drive friction and improving throttle response
• Oil Through System: Cusco's exclusive Oil Through System promotes efficient oil circulation — flowing from the wide end through the pressure rings to the clutch plates for superior lubrication and thermal stability
• Radially Cut Clutch Plate Grooves: Exclusive groove geometry enables instant oil movement for improved efficiency and extended durability
• Polished Pressure Ring Surface: Ensures even, flat contact with clutch plates for consistent performance
• Reduced Clutch Plate Wear: Low-pressure clutch plate operation minimizes wear and deterioration compared to conventional cone plate designs
• Dual Cam Angle Settings: Two different cam angle settings are built into one LSD unit, allowing adjustment of locking characteristics without purchasing additional parts
• Adjustable Plate Stacking: Responsiveness and locking behavior can be tuned by changing the combination and stacking order of clutch plates
• Competition Proven: The Type RS LSD has demonstrated reliability throughout a full All Japan Gymkhana Championship season without requiring a single overhaul
• Chromoly Steel Construction: Casing and gears are manufactured from chromoly steel for superior strength, durability, and optimal oil flow through large oil openings

Available LSD Configurations:

• 1-Way: Activates under acceleration only; acts as an open differential on deceleration — ideal for front-wheel drive and AWD front axle applications
• 1.5-Way: Activates under acceleration with reduced understeer on deceleration compared to 2-way — recommended for drivers sensitive to understeer
• 2-Way: Activates on both acceleration and deceleration — recommended for rear-wheel drive and AWD rear axle applications, and for aggressive driving or drifting

The Cusco Type RS LSD is a direct upgrade over stock viscous limited slip differentials (VLSD) and is built to perform in both daily performance driving and dedicated motorsport competition.
