PSC BIG BORE XD Steering Gear Ram 4500/5500 Diesel 2017+ SG859 SG859R

Heavy-duty trucks need heavy-duty steering - and that's exactly what PSC's BIG BORE XD Steering Gear delivers for your Ram 4500 or 5500. Whether you're hauling, towing, or working your truck hard every day, this gear is built to handle it without breaking a sweat.

This gear series is 100% brand new (no core charge), and it's a direct replacement for Mopar 68236674AD. It's tuned with PSC's ported and balanced valving for smoother control and better road feel, even with oversized tires or heavy loads.

Want even more muscle? The Cylinder Assist version adds hydraulic power to help turn those big tires like they're stock - especially handy when you're loaded down or off-road.
