Product details
Big Bore XD2 Cylinder Assist Steering Gearbox for 2007-18 Jeep JK The stock JK steering box? It’s fine for stock tires and errands. But throw on 37s, a locker, and a weekend in Moab, and that thing’s begging for mercy. The BIG BORE XD® is the fix—built with a beefy 45mm sector shaft and a reinforced case so it won’t twist, crack, or cry when you crank it hard. Pair it with a PSC High-Flow Pump Kit and you’ll feel the difference the first time you turn the wheel—smooth, strong, and no more arm wrestling at the trailhead. Optional Items: PK38JP1 – High-Flow Pump Kit for 3.8L JK PK36JP1 – High-Flow Pump Kit for 3.6L JK
