This the AGR Rock Ram steering system for the Jeep JK. This is the same steering system Tony used to race the 2020 KOH race.

The Original hydraulic assisted steering system designed and developed for competition rock crawlers, but the Rock Ram System will improve the off road and on highway handling of any vehicle running larger than stock tires.

It works equally well on weekend trail riders, hardcore rock crawlers and the 4 Wheel drive with large tire and a lift kit who rarely gets off road but needs additional steering to move the big tires into tight parking spots. The Rock Ram system increases your steering force yet 100 percent or more, yet still retains excellent handling characteristics for on road driving.

The Ram cylinder serves as an added assist to the gearbox and as a POWERED Steering Stabilizer. The Ram Cylinder uses dynamic hydraulic pressure to control the front end movement, not just cushion it and the results produce a smoother ride and increased steering control. The Rock Ram System consists of our competition and trail proven Super Ram Box, Rock Ram Super Pump, and the Rock Ram Hydraulic cylinder and install kit.

The AGR Super Ram Steering Box has been machined and ported and fitted with a properly matched Rock Ram Valve to provide the needed increased fluid flow to supply both the Ram Box and the Ram cylinder, not to be confused with the backyard conversion that results in a slow and sluggish steering system.

The AGR steering gear box is manufactured with light valving for turning ease. In additional to the tremendous increase in turning force the Rock Ram System reduces stress on the steering gearbox and your Jeep's frame by sharing the load with the Ram cylinder. The components and modifications include the Rock Ram system are purpose designed to provide pure turning power for off road maneuvering and at the same time stabilizing the front end while driving on pavement.

    Only the best for me

    When it comes to steering, i want the best. AGR has this kit dialed in enough for me to finish a brutal race like King of the Hammers in 2020. Highly recommended.
