PSC SK688R38JP1 Big Bore XD Adventure Steering Kit, Jeep Wrangler JK 3.8L (07-11)

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. PSC 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 PSC’s 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.
