T-2R (RaceMaster)

TorsenŽ Traction Differential - T-2R (Racemaster)

Torsen's T2-R RaceMaster Traction Differentials are ideally suited for rear wheel drive, truck, SUV, C-Clip, and high performance applications. The patented EQUVEX™ parallel axis gear configuration provides better management of gear separation forces resulting in low backlash and quiet operation.

Unlike conventional speed-sensing, limited slip differentials, TORSEN T2-R is a full time torque sensing, torque biasing system. Torque and differentiation are continuously managed between the two axles and biased instantaneously according to variable road conditions. TORSEN T2-R's patented parallel gearing system is designed to perform for the life of the vehicle.

The TORSEN T2-R takes the T-2's performance to the next level. By combining the patented Equvex gearing from the Torsen T-2 with a coil spring pre-load and/or friction enhancing plates, the Torsen T-2R can remain locked, providing torque to both wheels, under low torque inputs. The addition of the friction plates allows the Torque Bias Ratio (TBR) to be tailored to differential design needs. These features allow improved mobility and traction under extreme conditions. In addition, it is compatible with electronic traction control, providing the ultimate in traction management systems.

MULTIFUNCTION CAPABILITIES The TORSEN T-2R is an advanced multifunction traction differential providing continuous, uninterrupted torque output, torque biasing, and differentiation in one integral unit. Since it can be preloaded, it is capable of remaining locked with low torque inputs, enhancing traction and mobility under extreme split ľ conditions. It is always active, responding instantly to torque feedback from variable driving conditions.

ENHANCED AND COMPETITIVE PERFORMANCE Split Coefficient Chart for the Torsen T-2R

The TORSEN T-2R's capability to immediately respond to variable driving conditions not only provides better traction, it also enhances the general performance of a vehicle. There is a marked improvement in total tractive effort as compared to open or conventional limited-slip differential equipped vehicles. In addition, the exceptional efficiency of the T-2R allows the engine's torque output to be used more effectively, delivering more horsepower to the road. The combined improvement in traction and the augmented power results in a nimble yet sure-footed vehicle that provides better handling, increased acceleration and an improved margin of safety.

Note - Preload is NOT available on all models and is design specific!

T-2R APPLICATIONS By adding preload springs (this is design specific), the TORSEN T-2R will stay locked with low torque inputs. This allows the vehicle to maintain drive, and thus momentum and mobility, during extreme conditions such as inside wheel spin or lift in a corner, or starting from a complete stop on split ľ grade. When the ring gear torque overcomes the preload, the unit will differentiate and bias normally, behaving like a conventional Torsen T-2. This is particularly useful to drivers who compete in road racing and autocrossing, as well as drivers of unladed pickup trucks, or SUVs who have to deal with poor weather conditions, or an occasional off-road trail, or for anyone who wants the best traction possible for their street car. The current applications for the TORSEN T-2R include the Ford 8.8 inch axle, the GM 8.5 inch axle, and the GM 7.6 inch axle.

A PROVEN WINNER The TORSEN T-2R is a proven winner on the track. In its first season, a T-2R equipped Ford Mustang Cobra driven by John Ames finished first in the E Street Prepared Class at the SCCA Solo 2 Nationals in Topeka, Kansas. Steve Eguina, driving a T-2R equipped Chevrolet Camaro SS finished third in the same class. These two will be the ones to beat in the ESP class for next season!
