This BIG BORE XD Cylinder Assist Kit is the ultimate steering upgrade for your 2020–2024 RAM 2500 or 3500. Built to handle big tires and heavy loads, it delivers rock-solid control without fighting the wheel. Everything’s bolt-on, lane-assist friendly, and tuned by PSC for smooth, confident steering whether you’re towing, hauling, or crawling.

Heads‑up for installers

Double-check hose routing and bracket alignment before tightening everything down. This kit is designed for a true bolt-on install—no mods needed if you follow the steps.

Before you order, we recommend double-checking your axle’s
steering travel measurement to make sure you get the right kit. If you’re not sure how to measure, there’s a quick ‘How to Measure’ video at the bottom of this product page to walk you through it.
