PowerTrax Grip Pro Traction System - Ford 9'', 1966-86 Ford Bronco & Truck

Powertrax Grip Pro Limited Slip Differential

Improve traction and drivability with the Powertrax Grip Pro Limited Slip Differential for Ford 9-inch rear axle applications. Designed to provide enhanced traction without the harsh engagement characteristics of a full automatic locker, the Grip Pro delivers predictable power transfer to both rear wheels while maintaining excellent street manners.

Unlike traditional clutch-type limited slip differentials, the Grip Pro utilizes a clutchless design that eliminates the need for friction modifiers and clutch pack maintenance. This low-maintenance differential provides reliable traction for street, towing, off-road, and performance applications while offering smooth operation and long service life. Available in both 28-spline and 31-spline configurations to match your Ford 9-inch rear axle setup.
