Cusco LSD 181 L15 Type RS Limited Slip Differential 1.5 Way Rear

The Cusco LSD 181 L15 Type RS Limited Slip Differential delivers exceptional traction performance for Subaru Impreza WRX (GC8) and Legacy (BD5) vehicles. This 1.5-way configuration is specifically designed for high performance street vehicles, providing the ideal balance between aggressive acceleration and controlled deceleration.

Key Features:

• Type RS coil springs absorb initial torque for gentle, progressive engagement
• Lower initial torque compared to Type MZ results in reduced friction and more efficient power transfer
• Inner-coil spring design maintains consistent, even pressure across friction plates while prolonging plate life and preventing deformation
• Reduced clutch plate pressure improves durability and minimizes chatter
• Adjustable design allows selection of 2 of 3 settings with simple overhaul
• Lower operating pressure extends LSD oil change intervals

The 1.5-way configuration activates under acceleration with less understeer during deceleration than a 2-way LSD, making it ideal for drivers looking to reduce understeer. This differential transfers extreme power without slipping and responds quickly to pedal inputs, making it perfect for drag racing or drifting applications.

According to Cusco's research, the Type RS offers 50 to 70% lower initial torque compared to conventional cone plate LSDs, resulting in improved response and reduced drivetrain power loss. Manufactured 100% in Japan and tested in-house, this limited slip differential represents Cusco's commitment to precision engineering and performance excellence.
