    Description

    Boss 302 Laguna Seca. Does your factory rear end just leave you spinning your wheels? Then upgrade to the same exact differential used in the Ford Racing "Boss 302 Laguna Seca" race car. This limited slip differential (lsd) uses a worm gear friction system that ensure your engine's power is transferred to the wheels for maximum traction.

    Application. This Ford Racing Boss 302 8.8" Differential will fit 2005-2014 solid axle equipped V8 Mustangs including the GT, Bullitt, BOSS and Shelby GT500. Requires 31 spline axles. Does not fit IRS applications.Application Note: 1986-2004 V8 Mustangs came factory equipped with 28 spline axles, except for 2003-2004 SVT Cobras which were 31 spline. All 2005 and newer V8 Mustangs come equipped with 31 spline axles.

    Specifications:
    • 8.8" Limited Slip Differential
    • Will accept anti-lock exciter ring
    • Requires 31 spline axles
    • Requires 3 quarts Gear Oil
    • Requires 4 ounces of CM-19546-A1 friction modifier with initial fill
    • Fits solid axle only

    Technical Note. You will need to reuse your factory 8.8” gear set, or upgrade to a new set of our 8.8" rear gears for this Limited Slip Differential. No aftermarket gears are included. For normal driving conditions we recommend you use 75W 90 rear gear oil. This will give you the same oil weight as factory. For colder temps or race use try 75w 140.
