The Yukon Trac Loc replacement unit is a clutch-type limited-slip differential for Ford Super 8.8" rear housings, offered for 2015–2020 F-150 applications with 34 splines. The less-aggressive, street-friendly Trac Loc clutches maintain tire synchronization by transferring torque to the wheel with better grip, providing improved traction for daily-driven vehicles and mild off-road use.
