undefined Lockers, Posi-Tracs & Spools

For all the serious off-roaders out there, you know the importance of having top-notch traction. Prepare your rig for anything by equipping it with a trac-lok differential and a locking differential. There won’t be a hill you can’t handle. Or, if you prefer race cars to big trucks, a spool differential is just what you need to keep your axles locked in place and ready to race. We have all of the different types of differential add-ons you need, right here.
For superior off-road and race performance, your ride needs the added traction that differential spools, slip differentials and locking differentials have to offer. The overall purpose of locking your axles together is to allow your ride to grip the ground more securely. All of your lockers, posi-trac and spool needs are backed by our 1-year, lower price guarantee and ship for free in the United States.
