Description

The Yukon YC F318-C Trac Loc positraction differential is engineered for Ford 8.8-inch axles, specifically those with 31 spline axles. This unit is built to provide enhanced traction by distributing power evenly to both wheels. It incorporates carbon fiber clutches for improved performance and durability, and is cast and machined to exacting specifications for high strength and tight tolerances, ensuring a long service life. This positraction differential case comes complete with spider gears. It is designed for a direct fit on Ford 8.8" axles with 31 spline configurations. The use of carbon fiber clutches contributes to its performance and longevity compared to traditional materials. Yukon Gear & Axle manufactures this component with a focus on precision and reliability. Fitment information for this specific model indicates it is compatible with Ford 8.8" axles featuring 31 spline axles. Some sources mention fitment for specific year ranges such as 1983-1996 Ford Bronco and 2003-2011 Ford Crown Victoria, though explicit vehicle application data may need to be verified manually as stated by some retailers.
