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.

* Please note that the 2007-18 JK Models including Rubicon and 2003-06 Rubicon uses the 3.73 & down carrier because of the OEM thick gears.
* Wrangler JK (Non-Rubicon) - All Gear Ratios
Double Drilled - 7/16" & 1/2" Holes
Eaton recommends a petroleum/mineral based GL-5 75W90 gear oil for all Truetrac differentials.
Do not use synthetic gear oil or friction modifiers.
