Description

The Detroit Truetrac was the first type limited-slip differential in the industry. The patented design of parallel axis planetary helical gears provide a quiet, automatic splitting of torque. Power transfer goes literally unnoticed by the driver, even in front-wheel drive axles! The Truetrac performs like an open differential under normal driving conditions and automatically transfers torque to the wheel with better traction when ground conditions warrant.

Note: Fits 76-06 Jeep CJ, Wrangler YJ, & TJ with 3.73 & numerically lower gear ratios. Fits 07-18 Jeep Wrangler JK with all gear ratios..

Note: 2007-18 Jeep Wrangler JK require drilling 1/2" holes to match the factory original JK ring gear.
