Cusco LSD 985 V15 Type RS Limited Slip Differential 1.5-Way Rear

The Cusco LSD 985 V15 is a Type RS Limited Slip Differential engineered for high-performance rear-wheel drive applications. This precision-manufactured differential replaces factory open or Torsen differentials to dramatically improve traction, cornering stability, and overall driving dynamics.

1.5-Way Configuration:

The 1.5-way design provides full engagement during acceleration and partial engagement under deceleration, offering the ideal balance between performance and street drivability. This configuration activates under acceleration while reducing understeer during deceleration compared to a 2-way LSD, making it perfect for drivers who want aggressive grip without excessive oversteer when lifting off the throttle.

Type RS Technology:

• Special precision coil springs located between pressure rings develop initial torque smoothly and progressively
• Initial torque is 50-70% lower than conventional cone plate LSDs, enabling lower drive friction and better response
• Radially-cut clutch plate grooves enable instant oil movement for improved efficiency and durability
• Polished pressure ring contact surfaces ensure even, flat contact with clutch plates
• Cusco Oil Through System enhances circulation and oil supply to critical areas
• Low chattering and minimal power loss for improved lap times even in mildly tuned vehicles
• Reduced clutch plate wear and deterioration compared to cone plate designs

Competition-Proven Performance:

The Cusco Type RS LSD has proven its capability in the All Japan Gymkhana Championship, running entire seasons without requiring overhaul while delivering championship-winning results. This differential optimizes power transfer to both rear wheels, eliminating the power loss and wheel spin common with open differentials during cornering, acceleration on slippery surfaces, or when one wheel loses traction.

Manufactured in-house at Cusco's ISO 9001 certified facilities in Japan, ensuring the highest quality standards from design through production. The Type RS is specifically designed for high-performance street use, offering the perfect combination of track-ready performance and daily drivability.
