What a lot of off-roaders who are new to the hobby don’t realize is the effect that larger tires, locking differentials, and modified suspension geometry have on their vehicle’s power steering system—but they often find out quickly as they struggle to maintain control of their rig when they hit the trail.
That’s why the off-road aftermarket has stepped up to offer hydraulic steering assists that include things like an upgraded steering pump, steering box, steering cylinder, and hydraulic lines. Available as universal systems for folks building custom rigs with popular axles from Dana and Rockwell, as well as for specific truck models from manufacturers like Chevy, Ford, Dodge, and Ram, these hydraulic steering upgrade kits help you navigate the trails with confidence.
Adding a hydro steer kit to your steering system not only makes your trail runs more enjoyable, it can make your off-roading safer, giving you more control over your vehicle. And, depending on the application, these kits contain what you’ll need to get started, from the steering box and steering ram, all the way to the hydraulic steering pump and hardware necessary for installing your hydraulic steering kit on your off-roader.
If you’re planning on running oversized tires, lockers (front or rear), or if you’re looking to significantly alter your truck or SUV’s chassis or suspension geometry, don’t wait until you’re stuck between a literal rock and a hard pace to discover your steering system needs an upgrade, spec out your build now and add a hydraulic steering assist system to your project’s parts list. To help, you can choose your hydraulic steering kit based on things like your drivetrain, vehicle make/model, and your tire size—all the way up to a massive 55 inches!
When you’ve determined which hydro assist steering kit will work best for your ride, you’ll be able to find it right here at SummitRacing.com.

Through years of research, development, and testing Trail-Gear has developed these Rock Assault double-ended ram kits—to meet the tough demands of top-level rock crawling competitors and the toughest trails in the world. Most rams on the market only have one rod seal. Trail-Gear started with the primary and secondary rod seal to insure that fluid leakage would never be an issue. They also included two wiper seals in the design to ensure that dirt and debris stays on the trail—and doesn't invade your steering system. In addition, the ram was designed with a triple-lip piston seal for consistent steering with no drift or fluid bypassing the piston. In true Trail-Gear style, the Rock Assault kits are engineered to be the strongest on the market, so they're designed with a piston wear band and a rod bushing. This bushing allows the rod to absorb much higher side loads. The piston shaft is machined from a single piece of 4340 chromoly. Trail-Gear Rock Assault double-ended ram kits are available with a 6, 8, or 10 in. stroke. The cylinder has a black zinc plated finish, while the rod has 3/4-16 in. female threads on each end.
