The Detroit Truetrac is the leading helical gear-type limited slip differential in the industry. Eaton has a proven track record of producing the most effective and dependable traction differentials in the world. Truetrac's patented design of parallel axis planetary helical gears provides a smooth and quiet automatic division of torque. Power transfer is so smooth it is typically unnoticed by the driver even in front wheel drive axles. Although Truetracs offer the highest bias ratio in the forward direction they also exhibit a slightly reduced bias ratio in the reverse direction or during engine braking. The bias performance of the Truetrac complements and enhances brake-based traction control systems. Under normal driving conditions Truetrac performs like an open differential. On wet muddy icy or loose terrain imbalanced gear forces automatically transfer power to the wheel with the highest traction. The Truetrac limited-slip differential responds instantly to torque feedback providing needed traction anytime at any speed. Truetrac differentials are engineered to work efficiently in front and rear axles and transfer cases. Designs exist for C-clip full-float semi-float and snap-ring style axle configurations. Proven design low cost and effective performance all make the Truetrac limited-slip differential the ideal choice for a wide variety of vehicle applications including road racing off-road competition emergency vehicles motor homes and commercial trucks.
