PSC PERFORMANCE Big Bore XD Steering Gearbox (2003-2008)

Got a Dodge Ram with that sloppy steering feel? Yeah, we know the struggle. The factory box just can’t keep up, and that “Dodge steering wander” is enough to drive anyone crazy. That’s why we built the BIG BORE XD Steering Gear—a heavy-duty, brand-new replacement that bolts right in and fixes the problem for good.

We took inspiration from Mopar’s “Big Box” and made it even better. Bigger bearings, beefier internals, and zero core charge. Just swap it in, hook up your factory lines and Pitman arm, and you’re back on the road with steering that feels tight and confident.

*No More Steering Wander: BIG BORE XD gear features a 45mm sector shaft bearing (vs. 35mm stock) to eliminate slop.
*Built for Bigger Builds: Cylinder Assist Kit handles the extra torque from oversized tires, lockers, and heavy-duty axles.
*Road-Friendly Feel: Tuned for daily driving—no twitchy oversteer or arm-wrestling the wheel.
*Bolt-On or Weld-On Options: Choose what fits your build and install style.
*Zero Core Charge: All-new parts, no rebuilds, no hassle.
