Key Benefits of RSX Torsen (Gear-Type) LSD

Maintenance-free design
No clutches or friction plates to wear out.

Smooth and progressive torque transfer
Eliminates sudden locking for stable and predictable handling.

Ideal for mixed-use vehicles
Perfect for daily driving, performance driving, and track-day use.

Significant lap time improvement
Compared to open differentials, RSX Torsen LSDs improve lap times by approximately 1 second per kilometer on average, based on extensive testing across:

• Circuit racing
• Tarmac & gravel rally
• Rallycross
• Hill climb
• Drag racing

Manufacturing Process & Materials

Manufactured from FORGED Nickel-Chromoly steel

Advanced treatments for maximum durability:

• Super sub-zero treatment
• Shot peening
• WPC surface finishing

These processes significantly increase surface hardness, making the LSD suitable for high-torque and high-horsepower applications, including turbocharged engines exceeding 1,000 hp.

Our in-house high-angle helical gear design provides exceptional traction and cornering performance, surpassing even some plate-type LSDs currently on the market.

Important Installation & Oil Recommendation

Use OE or fully synthetic gear oil

DO NOT use shockproof oils or oils with friction modifiers (“LS” oils designed for plate-type LSDs)

Add gear oil directly to the LSD during gearbox assembly
(Anti-rust oil used during factory assembly does not provide lubrication)
