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.

Heads‑up for installers

  • Gear works with OEM pressure/return lines and 2003–2008 Pitman arm
  • Cylinder Assist Kit requires welding
  • Not compatible with most aftermarket steering braces (including SB300K)
  • PDF and video install guides available
