Cusco LSD 120 C Type RS Limited Slip Differential 1-Way Rear

The Cusco LSD 120 C Type RS Limited Slip Differential uses advanced spring technology that keeps differential noises to a minimum while improving durability and reducing power loss. This Type RS LSD is available in a 1-way configuration and is most suited for high performance street vehicles.

Advanced Spring Technology:

• The inner-coil spring design allows for lower initial lock on friction plates while achieving similar response to traditional LSDs, keeping plates in contact evenly and prolonging their life
• Chattering of the plates is minimized by providing consistent pressure across the radius of the friction plates
• Smoother and quicker initial clutch plate engagement from non-operational to fully functioning state, even with a low initial torque rating
• Initial torque is 50 to 70% lower compared to conventional cone plate type LSDs, enabling lower drive friction and better response

Performance Benefits:

• 1-way operation is specially suited for front wheel drive cars and 4WD car front axles
• Exclusive Oil Through System enables better oil flow inside the LSD with large oil openings for efficient lubrication and enhanced stability
• Proven capable of competition use in the All Japan Gymkhana Championship without overhauling a single time during the season
• Backed by Cusco's long-time development and extensive LSD knowledge, producing some of the most versatile, durable and effective LSDs on the market

This differential is designed for specific applications including Mazda Familia BG8Z and Mazda Roadster NA6CE models. The Type RS design offers gentler engagement and smoother transitions compared to traditional cone-plate LSDs, making it ideal for drivers seeking improved traction with minimal noise and maximum durability.
