Yukon Gear Trac-Loc For Ford 8in With 31 Spline Axles. Street Design

This Yukon Trac-Loc limited slip differential is designed for Ford 8-inch rear ends with 31-spline axles. It's a positraction unit that aims to give you smoother, more consistent traction, whether you're driving on the street or tackling varied terrain. This particular model features a smooth design with lighter preload springs, making it a solid choice for everyday driving and street use.

Inside this unit, you'll find forged 4320 chromoly spider gears, known for their strength and durability. The differential also uses composite clutches to manage the limited-slip action. Yukon builds these units with a strong nodular case and they are designed to be fully rebuildable, meaning you can service them down the road if needed. This unit is assembled in the USA and has undergone extensive product testing.

This Trac-Loc fits a wide range of Ford and Mercury vehicles from the 1960s through the early 1980s, including models like the Ford Mustang, Mercury Cougar, and Ford F-100 Econoline. It's compatible with all gear ratios for the specified axle and features a 4-pinion design for added strength. Keep in mind that this unit requires Trac-Loc bolts and is designed for use with light springs for a smoother engagement.
