4wd vs 2wd steering box - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Want this but it says 4wd applications. Didn't 4wd trucks just have different pitman arms? I don't see why agr would make a 12 ratio for 4wd vehicles and not 2wd

how the arms mount are different too. 2wd have the nut in the middle clamping the arm down. 4wd have a bolt through the side of the pitman arm. you could open it up and swap the shalfs, but if you spend that much I wouldn't want to crack it open,lol

Doesn't the 2WD steering cross over and connect to the passenger side wheel? while the 4wd version connects to the driver-side wheel. I have a 4WD, but I know that the aftermarket crossover steering kits require you to swap to a 2WD steering box because of the way the pitman arm mounts.

4wd box the Pittman arm can only go on one way. 2wd box has a nut on the end of the shaft to lock the arm on as the arm is tapered. Im pretty sure the 2wd arm can be clocked.

I've taken all the guts from a cracked 4wd box and put them in a 2wd box, just my .02

Just thought of something, if that's a quick ratio box the gears in it are likely different and stock parts probably wouldn't work.
