 If your Jeep is like most, it has a stock differential. While this type of differential is effective for most off-road obstacles, it can leave you frustrated in extreme situations. Add Jeep lockers to your rig to lock both wheels on an axle together. Instead of watching one wheel spin while the other stays put, you make real movement getting out of sticky situations with a locker assembly. While you are at it, don’t ignore overall problems with your axle assembly. If you need to order a new axle assembly for Jeep vehicles, we have you covered.

Locking differentials like this Eaton Dana 44 30 Spline 3.73 Down 4 Pinion E-Locker helps keep both wheels turning at the same speed, even if one has lost traction. This can be a lifesaver when you're stuck in the mud or climbing a steep hill.

Complete Axle Assembly
When the stock axels just won't cut it anymore, the next step is upgrading it to a complete axle assembly. This allows you to start with a blank slate and build the Jeep of your dreams, with all the offroad capability you could ever want.
