Rock-AssaultTM Steering Pump Kit

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.

Pump kit includes pump, pump bracket, reservoir, reservoir bracket, belt, fittings,  hoses, & hardware. Pump kit is designed to work with stock or ram drilled IFS power steering boxes.

Application Notes: This pump and bracket is designed to fit all Toyota 4cyl 4wd motors from 1979 - 1995. A large power steering fluid cooler (included) is required on the low pressure side of the system. Pump bracket works in conjunction with stock idler bracket. If your truck is not currently equipped with power steering, you will need to purchase the idler bracket and replace the steering gear box with one designed for use with power steering. The stock fan belt will not work with this pump and will need to be replaced with Napa # 9440 belt. Belt is included with kit.

Note: Never use ATF fluid, or a semi-synthetic blend. This will void the warranty.

Ok to use standard power steering fluid or a full synthetic.

Royal Purple fully synthetic power steering fluid recommended.

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.
