Trail-Gear Power Flow Power Steering Pump Upgrade Kits

Trail-Gear Power Flow power steering pump upgrade kits remedy a common flaw in Toyota trucks. The stock pump is just barely able to supply the volume and pressure needed to run hydraulic-assist steering—putting out 1,300 psi at only one gallon per minute. The original pump is not able to provide enough fluid to run both the stock steering and the demands of a ram, especially at low rpm. 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. This provides the full fluid volume your steering box and ram are looking for, even at idle. These kits include a 1,650 psi pump, pump bracket, reservoir, reservoir bracket, belt, fittings, hoses, and hardware. The pump kits are designed to work with stock or ram drilled IFS power steering boxes. Additional notes: * The pump and bracket are designed to fit all Toyota 4-cylinder 4WD motors from 1979-95 * 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 gearbox 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 a Napa 9430 belt. Belt is included with kit. * Note: Never use ATF fluid or a semi-synthetic blend. This will void the warranty. It's okay to use standard power steering fluid or a full synthetic.

Hellwig Frame FX Kits

One of the most effective ways to improve the stiffness and handling of your vehicle is to box the factory chassis. Hellwig Frame FX kits makes it easy for you. Rather than taking considerable time with measuring, cutting, and fitting steel panels these kits simplify the process effectively. Some vehicles have an open C-channel chassis that's only 3 in. wide at the top and bottom. This design is inherently weak in handling torsion and marginal in bending. Frame FX kits double the width of the tension side of the frame rail and close the area for dramatic increases in torsional and bending stiffness. They're comprised of 14 pre-cut 10-gauge steel panels matching the thickness of the factory frame--and fit into the weak points of the factory chassis. Hellwig engineered another panel that adds an extra mount to tie the floor to the chassis, furnishing even more strength to the entire car. In addition, brackets are provided to mount the transmission crossmember, with enough adjustment to accommodate nearly any drivetrain configuration. The increased strength via Hellwig Frame FX kits results in improved handling and ride quality, while retaining the factory chassis and mounting points.
