If you’ve been fighting that sloppy steering and cooking your pump every time you hit the trail, this kit is your ticket to a better day behind the wheel. We built it for the JK guys running the 3.8L who want steering that feels solid and stays cool, even when you’re locked up and crawling.

This isn’t some “bolt-on and hope” setup. You’re getting our Big Bore XD® Steering Gear for serious torque and a high-flow pump kit that keeps the fluid moving and temps down. Toss in the cooler, upgraded hoses, and PSC fluid, and you’ve got a system that’ll handle 35s without breaking a sweat—and without needing a full assist cylinder.

Bottom line? It fixes the play, kills the heat, and makes your Jeep steer like it should’ve from the factory.

Heads‑up for installers

  • If you’re running a Synergy MFG Track Bar Brace (or similar), you’ll need HWK-688-PP and SYN-8869-10.
