This kit’s built for the early Jeep Cherokee XJ crowd — the ones still running strong and ready for more. The PK40XJ1 Cylinder Assist Pump Kit gives you everything you need to upgrade your steering system with a high-flow pump, remote reservoir, cooler, and all the right plumbing to support a Cylinder Assist setup. It’s designed specifically for non-ABS 1987–1995 XJs, and it’s the same setup we’ve run on our own trail vehicles. No guesswork, no mismatched parts — just a solid, proven system that keeps your steering cool, quiet, and responsive.
