      High-Performance Differential. The Eaton Posi Ford 8.8-Inch Limited Slip Differential, featuring 31 splines, is engineered to enhance traction and vehicle control under demanding driving conditions. It distributes torque efficiently between wheels, improving handling on both road and off-road surfaces. This limited slip differential maximizes grip and ensures consistent power delivery for street, muscle, towing, and light off-road applications.

      Construction and Appearance. Constructed from durable steel, this differential includes an 8.8-inch ring gear and 31-tooth spline gears. It is precision-engineered for strength and reliability, supporting a range of gear ratios and heavy-duty use. The exterior finish is designed to resist corrosion for long-lasting performance.

      Application. Compatible with 2011-2014 Mustang V6 and 1986-2014 V8 Mustang models, excluding 2013-2014 GT500 versions, this differential suits most popular Mustang configurations from those years.
