*Requires a ported steering gear. This kit will not work without one.* Big tires and heavy trucks don’t play nice with stock steering. That’s where this Cylinder Assist Axle Kit comes in. It takes the fight out of the wheel, keeps your truck tracking straight, and saves your steering box from a short, miserable life. This kit is built around our proven Cylinder Assist system —the same setup hardcore off-roaders and work trucks have trusted for years. Whether you’re running an early Dodge (2003–2013) or a newer RAM (2014–2022), we’ve got you covered with the right hoses, mounts, and hardware for a clean install.
