  1. Pitman Arm Tech

    The pitman arm is a key part of any steering system involving a steering box, since it’s literally the part that bolts to the output shaft of the steering box.  So here are some details about various GM pitman arms and why we use the parts we do.


    In the GM squarebody (and even earlier) world, the 4wd trucks use a different steering box output shaft and pitman arm arrangement than 2wds.  On a 4wd, the pitman arm points to the side of the truck and the draglink runs toward the back of the truck to the steering knuckle.  On a 2wd, the pitman arm points straight back and moves the centerlink side to side to move the tierods to steer the tires.

  2. "I got some new big tires, what gears should I put in my axle?"

    Here’s a question we get all the time:  “What axle gears should I use for my combination?”


    Obviously there are a lot of engine, transmission, tire size, vehicle weight and intended use combinations but here are some general guidelines and specific recommendations.


    In general we like to gear a lifted truck to run more RPM rather than less.  Usually a lifted truck ends up with bigger tires, exterior accessories that add aerodynamic drag, the lift itself adding aerodynamic drag and often bigger axles, transfer cases and transmissions that make our power requirements greater.  Your typical lifted K5 Blazer can very easily end up with the equivalent load of a loaded down pickup so we tend to look at gearing systems for heavier rated factory trucks or towing packages for lighter rated factory trucks.  The big thing you see is that they’re geared deeper, no big secret.


    The first thing to consider is if y...

  3. Kevlar Bushing Update


    We are working with a second generation Kevlar reinforced polyurethane bushing material that is proving to be another step stronger and more durable.  At this time the new material is only available in the same grey color as our Kevlar tierod end boots.  Due to shortages in all our materials we are not able to offer most of our kits in all grey or all black for immediate shipment.  If we ship at regular in-stock timing you will receive a mix of grey and black and we have very limited control over what bushings are what color.  We understand some of you are working on some super good looking truck builds and we don’t mind a bit doing all we can to make our stuff match for you.  To help you keep it all looking matched up we are offering the option to hold your order and ship all black bushings as they are available.  This option will be a mix of our Kevlar bushings and regular polyurethane but the colors do match and will be all black.  T...

  4. Reloaded pages from the old website: ORD on the trail

    Here is a reloaded page from our old website


    This section shows you ORD rigs and our customers' rigs in action on the toughest and best trails in the country. 

    We've grouped these photos roughly by suspension type -- leaf springs front and rear;  front coils with rear leaves; and coil springs at all four corners.  Whichever setup you like, we're pretty confident that we -- and ORD customers -- have built and 'wheeled the very best of each breed using ORD parts.

    KOH 2012 was GREAT!  We finished 12th overall out of a field of 137.  We're really hungry for a top 10 but this is our best finish yet and we can see the top from here.  We have pictures and comments on our Facebook page HERE.
    There are also some good pics on our photobucket page HERE.

  6. Re-loaded "Our 4x4s" from the old website: Cheap Truck

    Below is the build thread on Cheap Truck from our old website!


    One piece of advice we often throw out for anyone building a truck on a budget is to pick up someone else's truck or even just an abandoned project.  You can get a great deal on some good parts that way, or even pick up a complete running truck that just needs some tuning to get it dialed in.  Just to prove the point, we decided to put our money where our mouth is and now we have our "Cheap Truck".

    We actually had a local guy come to the shop to tell us about this truck he was selling because he was moving, hadn't used it in years and just needed it gone.  It's a '74 long bed 3/4-T...

  7. Re-loaded "Our 4x4s" from the old website: Burly Burb

    Below is the build thread on Burly Burb from our old website!

    This buildup runs in chronographic order, the earliest mods at the top and the latest mods at the end.

    Our green K5 has been getting a little bit biased toward trail use, so when it came time to pick up a general purpose traveling, camping, fourwheeling truck, we ended up with this '88 Suburban.  Now that 3 kids are part of the general traveling package, the full size rear doors are great to have and the cavernous interior means we can carry all the people and gear we need, and sleep in the truck too.

    The overall goal is to leave it low enough to get decent gas...

  8. Re-loaded "Our 4x4s" from the old website: Wally

    Below is the build thread on Wally from our old website!


    Wally, our K5, morphed again. This time in response to a bent and twisted front axle housing, a desire for better side clearance, a bunch of bent up metal and of course a desire to improve performance.


    Here it is on the trail in Poteau:

  9. Past 4x4 articles we had on our old website

    Below are some old magazine articles that we had on our website:

    We're grateful ( and kinda proud, too) that the major four-wheel drive magazines have included us in their pages, on their TV shows and videos so many times over the years.

    Below: Our green monster made the 4WOR cover!

    It gives us the idea that ORD products and our particular brand of 'wheelin wackiness must be on the right track!

    This is where we'll share some of our magazine coverage - features on our rigs, plus tech and installation articles involving our products. ...

  11. Leaning Truck?

    Below is a customer question about leaning springs and what to do to remedy the situation. We figured it could be helpful for many people:

    A lean is fairly common and is a byproduct of a soft spring and kind of unique to this truck platform because the front springs’ mounting width is fairly narrow. A small difference in the height of the springs can make an exaggerated difference in side to side height and a small weight difference can also also cause an exaggerated ride height change. To put some numbers on it, the springs are about 32” center to center and the outside of the body where you see and measure is about 80”. The body has about 2.5:1 leverage over the springs so a ¼” change at the spring pad should convert to 5/8” at the body line. It also works the opposite for weight, any weight change has a big lever arm over the springs and makes itself look way bigger than it should.

    We have yet to have a spring problem that was causing a lean so I’m bet...

  13. Throw back build thread of the UA2500 from the old Pirate4x4 days

    Below is the original text from the build thread copy and pasted here. Some of the text might not make much sense since some of the conversation is missing. To find the whole thread check out HERE

    Also you can find the parts we used HERE

    Now the only thing left in the truck is the long block.:shaking:
    We actually shopped a little for this truck, we wanted the 88-98 type body style with the big block and after our recent headaches with 4L80's we really wanted the NV4500. Plus I've never wheeled a properly set up truck (low geared) with a manual so it'll be fun driving something different. We wanted a running driving truck so that we wouldn't be building an engine...

  14. Hydro Assist Tech

    Best Way to Setup Your Steering Gearbox For Hydo Assist

    Recently we were asked about the steering box end caps and why we don't offer a tapped one for hydro-assist. Since this is an often asked question we figured the answer could help a few others out as well!

    "I'm planning a hydro assist conversion using the part below (tapped end cap for steering gearbox), tapping the other hole for the system in the aluminum cap on the top of the steering box (there's a link in his description to a video on youtube where a guy does this on a jeep). If you made a part like that, I'd buy it from you. Is there a specific reason that you don't make that, or wouldn't recommend...
