This BIG BORE XD Cylinder Assist Kit is built for Dodge RAM trucks that need serious steering muscle. When you’re running big tires and working that front end hard, factory steering just doesn’t cut it. This kit adds hydraulic assist to take the load off your steering gear, giving you smooth, confident control whether you’re crawling rocks or hauling heavy. Weld-on brackets keep everything locked down tight, so you can push your truck without worrying about steering failure.

Heads‑up for installers

This kit requires welding for proper installation. Make sure you’ve got the right tools and skills or a trusted shop to handle the job.

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.
