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

Scratch & Dent – SG856 Big Bore Steering Gear

Save with a scratch and dent version of the SG856 Big Bore Steering Gear! These units may have minor cosmetic imperfections but are fully functional, tested, and built to PSC’s high standards.

The SG856 is engineered to eliminate side-to-side movement of the sector shaft by utilizing a substantially larger lower sector shaft support bearing and increasing the sector shaft diameter to 45mm.

For improved load-pushing capability, the 80mm internal piston assembly works alongside a 16:1 steering ratio, delivering exceptional handling and effortless maneuvering.
