Is your stock 28 spline rear end leaving you stuck?
Then you need to upgrade to a Ford Racing 8.8" 31 Spline Traction-LOK Limited Slip Differential from AmericanMuscle. A Limited Slip Differential sometimes referred to as a "Posi" will allow both rear wheels to put the power down on the pavement giving you better traction and more impressive burnouts. The Ford Racing 8.8" Limited Slip Differential unit uses heavy plate-style clutches and is designed for use with after market 31 spline axles for 8.8" V8 Mustang. Great for the street or strip driving this differential will accept the anti-lock brake exciter ring found on most late model V8 Mustangs.
