The SARD TORSEN Type Racing is a premium torque-sensitive limited-slip differential engineered for drivers who demand exceptional traction and precise control on the circuit.

By retaining the inherently smooth lock-up characteristics of a Torsen design while significantly increasing the lock-up ratio, this differential delivers the ultimate balance of predictable road manners and race-ready performance. It is the choice of professional drivers and features in many circuit record-holding cars.

Product Highlights

🏁 RACE-PROVEN TRACTION PERFORMANCE
Developed for the highest levels of motorsport, this Torsen LSD provides superior traction that allows you to place the car exactly where you intend. Its predictable, smooth lock-up inspires confidence and enables more aggressive driving on the circuit, a trait highly praised by professional drivers.

🔧 HIGH LOCK RATIO FOR CIRCUIT DOMINANCE
Engineered specifically for sporty driving, this unit achieves a significantly higher lock-up ratio compared to a standard Torsen LSD (over 133% lock ratio under acceleration, and over 124% under deceleration). This is accomplished through a sophisticated two-part side gear design that uses helical splines to increase thrust force, dramatically improving traction without sacrificing the Torsen’s linear feel.

⚙️ SMOOTH, PREDICTABLE LOCK-UP CHARACTERISTICS
Unlike mechanical (multi-plate) LSDs that rely on initial torque and can cause abrupt changes in lock-up, the Torsen Type Racing generates lock-up proportionally to input torque. This results in minimal impact on vehicle posture during sudden on/off throttle transitions, such as those experienced during circuit driving, allowing for smoother and faster corner entry and exit.

🎯 CONSISTENT PERFORMANCE UNDER EXTREME CONDITIONS
Because the Torsen is a gear-based differential, its lock-up ratio is far less susceptible to degradation from rising oil temperatures compared to multi-plate clutch-type LSDs. This ensures consistent, reliable performance throughout a demanding track session.

🔰 NO CHATTERING NOISE
Due to its gear-driven structure, this Torsen LSD operates without the characteristic chattering noise often associated with clutch-type differentials, making it more refined for vehicles that may see both track and road use.
