We're now stocking PSC Steering Components and Kits!

PSC is the best name in offroad steering and is known for quality parts and the knowledge to get all the technical details just right. 

Offroad Design is one of the biggest stocking distributors of PSC components and we have become experts particularly in putting them to use in GM vehicles.  Here's a small sample of what we can do for you:

Extreme Duty steering boxes:

PSC starts with a picky inspection process for core boxes and combines the necessary used parts with as many brand new Delphi parts as possible for a premium rebuilt steering gear, these are as close to a brand new steering box as you can get.  The cases are honed and machined true as well as tested to insure proper flow balance.  The reconditioned parts are magnafluxed to check for microscopic cracks.  Includes a billet end cap and cover.  You can't buy a better steering box!

When converting a '67-'87 ('91) Chevy to crossover steering, you need a 2WD steering box, those are listed here:

Extreme Duty ported steering boxes:

Ported steering boxes are a great way to go if you are installing crossover steering and can't do a complete hydro assist kit.  You can install the ported box and run it with the ports capped off till you can add the pump system and assist cylinder.  The box itself is the same as the above Extreme Duty boxes, it is then strategically ported to allow fluid to flow through the circuits as efficiently as possible.  There isn't a better hydro assist ready box!

Hydraulic Assist Systems:

Hydraulic assist systems keep your steering box on the frame but pull extra hydraulic power from the box ports to operate a cylinder mounted directly between the tie rod and axle.  This more than doubles your steering power and removes a LOT of stress from the box, frame, and steering linkage.  Or lets you use all the parts just as hard and get through nastier stuff than ever before. (insert evil grin here!)  In some situations, the assist system will even tighten up the steering feel since roughly half your steering power is connected directly to the axle.

Do you need hydro assist?  We hear this question a lot so we put together some guidelines to help you decide if you really need it.  Click HERE to check them out.

Standard hydraulic assist kit for '80-'87 ('91) GM truck: $1154  (Click Picture for larger view)

Standard hydraulic assist kit for '77-'79 GM truck: $1184

Standard hydraulic assist kit for '67-'76 GM truck: $1184

Kit includes an Extreme Duty steering box, assist cylinder with hose kit, brand new high output pump with reservoir can on the pump and a filtered remote reservoir for greater fluid capacity and cooling.

Options include cylinder size (1.5" for more street driven rigs, 1.75" for extra steering power), 2WD/4WD box for crossover or standard steering, different hose fittings for various vehicles, cooler kits and hydroboost ready reservoirs (hydroboost option adds $30).
 

We also have an optional tie rod clamp, this allows you to attach the cylinder to the tie rod while still allowing you to adjust tow if you need.

Full hydraulic steering systems are also available. 
 
If you're running offroad only, full hydraulic steering may be the way for you.  The biggest advantage for full hydro is the lack of steering linkage, making it easy to put your axle anywhere you want under the vehicle.  It also makes it easy to minimize bump and rollsteer in link suspensions.  We use a PSC double ended ram system in Wally, our shop K5 truggy because we moved the axle about 7 inches forward from stock and using a steering box was no longer an option.  Full hydro kits can be driven on the road but they're what we would consider tolerable, not comfortable.  After a lot of on and offroad miles on different steering systems, if you're driving on the road much, go with an assist system.

A typical 2.5" double ended ram system like the one pictured is $1560.

Full hydraulic steering has many variables - single-end cylinders, double-end cylinders, various cylinder size options, etc. - so call us at 970-945-7777 and we'll help you build just the right setup for your rig!

ALSO, the parts above are just the ones that touch the steering fluid.  We also have ALL the rest of the steering beef you'll need that doesn't touch the fluid: Dana 60 Crossover Steering, Dana 44/10Bolt Crossover Steering, HD Steering Linkage, HD Steering Knuckles, etc.  Check those out and call us at 970-945-7777 for further information.  We can answer any questions you have.
