If you’re tired of wrestling that big GMC around on the trail or hauling heavy loads, this kit is the real deal. Our BIG BORE XD Steering Kit gives your truck the muscle it needs to steer smooth and easy, even when you’re running big tires or working it hard.
We’ve packed this kit with everything you need to do it right the first time: a beefed-up Cylinder Assist Steering Gear, a high-performance pump with a remote reservoir, a stout assist cylinder with all the hardware, and a full install hose kit. Top it off with PSC 715 fluid, and you’ve got a system that’ll take the heat and keep on working.
This setup is built for guys who want reliability, strength, and a steering system that feels like it should’ve come from the factory this way. Whether you’re crawling rocks, towing, or just want to make your truck drive like a dream, this kit’s got your back.
