Rock Assault Double Ended Ram and Clevis Kits
Through years of research development and testing we at we have developed double ended ram to meet the demands of top level rock crawling competitors and the toughest trails in the world. Based on our experience we knew exactly what we wanted in a ram and what we didn't.
Most rams on the market only have one rod seal.We started with the primary and secondary rod seal to insure that fluid leakage would never be an issue. We also included two wiper seals in our design to make sure that dirt and debris stay on the trail and don't get into your steering system. In addition,we designed our ram with a Triple Lip Piston Seal for consistent steering with no drift or fluid bypassing the piston.
In true Trail-Gear style we also had to make our ram the strongest on the market, so we added a feature that you will not see on any other ram on the market.We designed ours with a piston wear band and a rod bushing.The bushing allows the rod to absorb much higher side loads We also machined our piston shaft out of a single piece of Other rams on the market use a two-piece welded or threaded piston shaft that can fail under severe loads.

High Pressure Power Steering pumps
The stock Toyota pump is just barley able to supply the volume and pressure needed to run Hydraulic assist steering. The stock pump puts out 1,300 psi @ one gallon per minute. The stock pump is not able to provide enough fluid to run both the stock steering and the demands of a ram, especially at low RPM's. Drilling out the restrictor plates in a stock pump for more volume often leads to pump failure.The answer is a replacement "TC" style pump. The Trail-Gear Rock-AssaultTM pump puts out 1,450 psi of pressure at 4 gallons per minute. This provides the full fluid volume your steering box and ram are looking for even at an idle

Reservoir & Bracket
When installing a high flow pump such as the one listed above, it is important to use a larger reservoir to provide enough fluid when the system needs it. The sock reservoir is fine for the stock pump but is not adequate for the TC style aftermarket pumps. Side input of reservoir is a #6 JIC fitting and the bottom outlet to pump is a #10 JIC fitting. Reservoir includes cap.
Reservoir bracket makes it easy to bolt in the reservoir on most 4cyl 4X4 Toyota applications from 1979 - 1995. Includes mounting hardware. Unpainted finish.

Steering Fluid Cooler
If your running a high volume/pressure pump your system is generating much more heat then the stock system. Fluid overheating can cause damage to steering pump and steering box. Installing a oil cooler in front of the radiator is the best way to prevent this over heating. Our cooler features a fin area of 9" X 8" and does a great job of keeping the steering fluid temps under control in all conditions.

Orbital (Steering Control Valve)
(steering control valves) have a flow rate of 5.8 GPM and a built in return-to-center function. This means that when the driver releases the wheel the tires will automatically return to the center position. This is a convenient feature that allows for slow rock crawling or driving at higher speeds. The amount of turns it takes to get from lock to lock will depend on what ram you combine with your orbital. We have included a chart that will tell you exactly how many turns it will take to get from lock to lock with the different orbital/ram combinations, with the recommended combinations in bold blue letters.
