Description

PSC Big Bore XD steering gears are direct replacements for your inadequate steering gear. They feature larger piston diameters, which increase the torque output of the steering gear—allowing your rig to overcome steering issues due to larger tires and/or locking differentials that you've installed. PSC Big Bore XD units are assembled using all new components and featuring their exclusive new gear housing--not reworked core housings, but 100 percent new cast and machined housings. PSC also offers cylinder-assist versions for vehicles that have 38 in. and bigger tires and larger drivelines. Order the steering gears designed for fitment with your make and model.
