There’s no way we would come this far to run an open differential, so we chose the brutal strength and simplicity of a Detroit Locker. They’re bulletproof, they’re automatic, and you can simply throw the frontend in neutral for tight turning if you have a twin-stick T-case. For gears, we went with a set of 4.88s and master rebuild kit from G2 Axle & Gear. The G2 rebuild kit includes Timken bearings. For comic relief, Dana 30 4.88 gears are paired with the Dana 60 versions. Beefy!
