Cusco LSD 183 V15 Type-RS 1.5-Way Rear Limited Slip Differential

The Cusco LSD 183 V15 is a high-performance Type-RS limited slip differential designed to optimize power transfer and traction for demanding driving conditions. This rear differential unit features advanced engineering developed from over 40 years of Cusco motorsport expertise in rallying, track racing, autocross, and time attack competition.

Key Features:

• 1.5-Way design provides full engagement during acceleration and partial engagement under deceleration for balanced performance
• Type-RS coil spring design between pressure rings develops consistent initial torque across friction plates
• High-tension chrome-molybdenum steel housing and gears engineered for serious competition use
• Adjustable locking mechanism allows fine-tuning of differential lock characteristics to match driving style
• Large oil windows promote increased lubrication flow throughout the unit
• Cusco's original groove cut technology on clutch plates improves efficiency and promotes longevity
• Minimizes wheel slip by distributing power effectively to both rear wheels during acceleration and cornering
• Springs maintain even contact with friction plates, preventing deformation and reducing chatter

The Type-RS design utilizes an innovative inner-coil spring system that allows for lower initial lock settings while achieving response similar to traditional cone-type LSDs. This results in smoother, faster engagement with superior durability. The oil-through design ensures positive pressurized flow of differential gear oil through all components for optimal lubrication and cooling. Ideal for racecars, rally vehicles, track cars, and performance street applications where maximum traction and handling precision are essential.
