This full hydraulic steering kit is built specifically for Jeep Wrangler YJ platforms and set up to handle larger tires with a true double-ended cylinder. It’s a complete system designed to give you consistent steering control once a factory-style setup just can’t keep up.
Each option is matched to the correct engine and pump configuration for your YJ, so you’re not fighting fitment or chasing the right parts. You get the orbital, pump kit, hoses, fittings, and a 2.75" double-ended cylinder with an 8" stroke, all built to work together.
