At Yotamasters, we’re not just another off-road parts store, we're passionate Toyota enthusiasts dedicated to delivering premium-grade solutions for hardcore wheelers. That’s why we proudly offer the Rock Assault Ram Assist Steering Kit, the best hydro assist steering kit you’ll find anywhere for Toyota Pickups and 4Runners.
Designed for those who refuse to compromise, this kit is engineered to provide powerful steering assist, unmatched durability, and a seamless installation experience. Whether you’re rock crawling, trail running, or building a competition-grade rig, the Rock Assault Ram Assist Steering Kit ensures your steering system is as tough and capable as the rest of your build.
Made to Handle Tough Terrain
Off-road steering takes relentless abuse. Larger tires, high-steer systems, and rugged terrain put extreme loads on your factory steering box, making it harder to control your rig and increasing the risk of component failure.
That’s exactly why we built the Rock Assault Ram Assist Steering Kit to eliminate steering strain, enhance handling precision, and extend the life of your entire steering system.
Unlike generic kits that offer “universal fitment” with tabs you’ll need to modify yourself, our kit is specifically designed for Toyota axles and high-steer setups. Every bracket, fitting, and component is precision-crafted to integrate perfectly with your Toyota, so you can hit the trail with confidence.
This isn’t a bolt-on gimmick; it’s a professional-grade steering upgrade designed to perform flawlessly in the harshest conditions.

Main Benefits You Get
1. Heavy-Duty 3/4” Ram Rod – 50% Stronger than Competitors
Most kits on the market use a 1/2” rod, which is prone to bending under extreme loads. We upgraded ours to a massive 3/4” diameter rod, delivering 50% more strength and ensuring it holds up when you need it most.
2. High Temp Seals for Leak-Free Performance
Both inner and outer seals are rated for high-temperature environments, eliminating the common problem of fluid leaks under stress or heat soak.
3. Trail-Tested Hydraulic Ram
Our 6” stroke hydraulic ram delivers powerful and consistent steering assist, making light work of oversized tires and harsh trail conditions.
4. Engineered Brackets for Seamless Fitment
Forget about kits that make you fabricate or modify brackets. Our kit comes with specially designed, laser-cut brackets that fit your Toyota axle and high-steer setup perfectly.
5. Rapid Installation Time
Once your steering box has been tapped, installing the ram and brackets takes roughly one hour. We designed it for straightforward DIY installation without the headaches.
6. All-Inclusive Hardware and Instructions
No need for extra trips to the hardware store. We include all necessary fittings, hoses, elbows, and mounting hardware. Our detailed photo instructions walk you through every step.

We offer multiple ram size configurations to match your specific setup:
-
1.5” x 6”
