The stock Toyota pump is just barely able to supply the volume and pressure needed to run Hydraulic assist steering. The stock pump puts out 1,300 PSI at only 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-Assault™ pumps puts out  1,650 PSI of pressure at 4 and 4.5 gallons per minute respectively. This provides the full fluid volume your steering box and ram are looking for, even at an idle.

Pump kit includes  1,650 PSI 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 #9430 belt. Belt is included with kit.
