BIG BORE XD® Cylinder Assist® Steering Gearbox for 2009-2024 RAM 2500/3500

The SG856 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.
