Improves Rear End Traction for Better Handling and Off-Road Performance

The factory rear differentials of the 1997-2014 F150s with an 8.8" 31-spline rear end aren't really all that specially. Even the OEM LSDs and E-Lockers feature fairly basic designs that may not be adequate for all road conditions or off-road applications. When you need a serious traction upgrade for your F150's rear end, the Powertrax Grip Pro Limited Slip Differential can help. The Powertrax Grip Pro rear differential for the 8.8" F150s can help improve your F150's rear traction both on and off the road. Like most limited slip differentials (LSDs), the Pro Grip stays unlocked during normal driving and turning, but locks once slip between your rear tires occurs, which maintains power delivery to both the wheel that has the traction and the one that doesn't. Unlike more basic LSDs, the Grip Pro features a unique spiral gear operating mechanism that provides fast and smooth locking, progressive traction, an doesn't require friction modifier, making the Grip Pro the perfect for choice for any F150 owner looking for an improvement in traction both on and off the road.

Spiral Gear Locking Mechanism Inside Machined Forged Steel Case

The Powertrax Pro Grip LSD's specialized operating mechanism is paired with an extremely strong construction to create an LSD that won't let you and your truck down. Instead of clutch packs like a traditional or OEM-style LSD, the Pro Grip features a 3x2 spiral gear design that gives the Pro Grip a smoother and quieter operation than a clutch-type LSD, along with less locking delay. The spiral gearing also allows for progressive and variable traction based on your own throttle input, which gives you more control over the Pro Grip than a clutch-type LSD. The LSD's mechanism is built into a forged steel case that's fully and precisely machined so that it drops right into place of your F150's factory differential and works with any gear ratio on the market. The Pro Grip comes with everything you need for installation and is backed by a 2-year/100,000 mile Powertrax warranty.
