Gear Type

The factory steering on 2nd Gen Dodge RAM trucks? Let’s be honest—it’s weak. That’s why we built the BIG BORE XD Steering Gear, a serious upgrade designed to eliminate steering wander and give you the confidence to handle big tires, heavy loads, and tough terrain.

This gear is based on the newer Dodge XD platform, modified for a direct bolt-in fit on your 1994–2002 RAM 2500/3500. With a beefed-up 45mm sector shaft, larger bearings, and an 80mm piston, it delivers rock-solid steering and eliminates the need for aftermarket braces. Whether you’re daily driving or towing heavy, this is the fix your truck has been waiting for.
