You may have noticed that the steering performance on 2nd Generation Dodge RAM 2500 & 3500 4WD trucks is very poor, the result of the use of a small 36mm lower sector shaft support bearing and less-than-ideal placement in the housing. This original design has proven to be insufficient to handle moderate lateral stress loads encountered during daily on-the-road driving, much less in advanced off-road environments.

PSC has addressed these issues with the newly redesigned SG851 Big Bore Steering Gear. The SG851 all but eliminates side-to-side movement of the sector shaft by using a substantially larger lower sector shaft support bearing and increasing the diameter of the sector shaft to 45mm. Improved load-pushing capability is accomplished by an 80mm internal piston assembly and a 16:1 steering ratio delivers exceptional handling and effortless maneuvering.
