The ultimate in brute steering force for off-road vehicles. Originally developed for competition rockcrawlers, the ROCKRAM* system will improve the off-road and on-highway handling of any vehicle running larger tires. It works equally well on weekend trail riders, hardcore rockcrawlers or the four wheeler with large tires and a lift kit who rarely gets off-road but is fighting the wheel to get into a tight parking spot. The ROCKRAM* system is engineered for any vehicle needing extra steering force to turn large tires or maneuver off-road. The ROCKRAM* system increases your steering force by 100% or more, yet still retains excellent handling characteristics for on-road driving. The Custom Fabricated JK Xtreme BOX is built for Jeep Wrangler JKs, 2 and 4-door models. This is not a light duty 600 series stock box. It is a full on custom fabricated steering box with DOM extension tube which allows a much larger needle bearings for the sector shaft. Xtreme gusseting keeps the box from twisting and flexing. Kit includes 395851 Ram box, 1.5” Cylinder 931158, hose fitting and mount kit 930100, 826257 TC pump, 4 ¾” pulley. This cylinder and gearbox combination provides excellent turning force for tires up to 39.5” tires without compromising steering speed.
