ORD Spec Hydraulic Assist System for GM Trucks

Included is a 100% new high pressure high flow power steering pump and filtered remote reservoir system.  The pump will bolt directly in place of the stock truck power steering pump, the reservoir includes a couple different ways to mount it but there is some work involved in mounting the reservoir as there are many ways to do it on many different engines.

We use a #12 feed into the pump and #8 return line coming back from the steering box, these bigger lines help free up the system and let the pump flow more.  The higher flow means the system reacts faster and leads to faster steering.  Note that the bigger feed and return are only available on the '80 and newer o-ring style parts.  If you have a '77-79 truck, you can simply order the '80 and newer parts and they'll swap right on other than a new pressure hose from a parts store.  If you have a '76 and older GM truck, you'll need the pressure hose as well as a way to adapt the splines at the input of the box.  Either a later rag joint assembly or an aftermarket steering shaft (like Borgeson).

The "standard" in cylinders is 8" of throw, but this doesn't allow enough travel to get all the way to lock.  You can destroke a longer cylinder, but they get hard to fit and mount.  So we have our own scratch built 8-3/4" travel cylinders that hit the stops just right, the extra steering angle makes a big difference!

Also included is a 100% brand new (casting and all) PSC upgraded steering gear.  Bigger bearings, beefed up casting, and internally ported for the best flow to keep the steering quick.  You can't get a better steering gear box!

Of course all of the hoses and fitting are included to plumb everything together and mounting tabs are included with the cylinder.

The pressure hose from your current power steering system gets re-used. No need to replace it

Below are some examples of how we have our trucks setup. Of course if you have a GM axle it will just be mirrored:

The main goal when mounting the cylinder is having it push as straight as possible. If it pushes at an angle it can bend the tie rod.
