Description

The Detroit Truetrac 34 Spline Ford F150 8.8 is a helical-gear style, limited-slip differential designed to enhance traction by automatically transferring torque to the wheel with the most grip. It operates as a conventional open differential under normal driving conditions but engages when wheel slip is detected, effectively managing power distribution. It features a 6-pinion design, Super 8.8” ring gear compatibility, 34-tooth axle spline, and is suitable for gear ratios of 3.31 & Up. The unit weighs 36.0 lbs.
