Description

The PSC SG851 Big Bore Steering Gear improves steering performance on 2nd Gen Dodge RAM 2500/3500 4WD trucks. It features a larger 45mm sector shaft and increased lower sector shaft support bearing, addressing the common OEM single bearing failure point by eliminating side-to-side movement for better handling. This Extreme Duty replacement is designed with a 16:1 steering ratio, delivering 3.25 turns lock-to-lock, and a modern variable valve for stable on-road driving and effortless maneuvering.
