Vehicle/Model Year

If you’ve got a GM 4WD truck from the 70s, 80s, or early 90s and you’re running big tires or wheeling hard, you’ve probably felt that steering strain. This kit helps take the load off your steering box and gives you smooth, predictable control — even in rocks, ruts, and deep mud.

Designed around a crossover steering configuration, each kit is matched to your truck’s year range and pairs with PSC’s Cylinder Assist for added strength and control. Whether you’re restoring a classic or building a trail‑ready rig, it’s steering that simply works.
