Hydro-Assist Steering Box Tap and Bit Kit (1/4"-18NPT Tap with 7/16" Bit)

While larger tires are a good first step in increasing your off-road capabilities, it generally doesn't take long before you begin to experience the limitations of your power steering box. More challenging terrain requires better traction, and that means larger, low pressure tires which are physically punishing to steer at slow crawling speeds (especially in rigs with front differential lockers). With 35" and larger tires at low psi your rig will be almost impossible to steer while climbing and pushing against large rocks.

The solution is Hydro-Assist steering, which adds a double-acting hydraulic cylinder (with two ports for extension and retraction) to produces near irresistible linear force to move your wheels in the direction you want them to point. In fact, a young child turning the wheel could break the bead of a non-bead-locked tire against a rock with a Hydro-Assist setup.

How is the cylinder actuated? Your power steering box needs to be drilled and tapped to add 1/4"-18NPT x #6 JIC fittings and hydraulic lines on both sides of the power piston to force fluid into one of the two ports on the hydraulic cylinder to force your wheels left or right. Steering boxes are generally disassembled before tapping to ensure that any metal shavings can be removed to avoid damaging internal components.

Our quality Drill and Tap Kit is exactly what you need to add these ports to your steering box. It contains a 7/16" HSS Bit to prepare the holes and a 1/4"-18NPT Tap to cut threads for the hydraulic fittings.
