    Is it possible to put one of the quick ratio 16:1 steering boxs in a K5. Would it be cool or a joke? I just got to thinking because my box is worn out in the middle (yes i have adjusted the bearing preload and over-center adjustment) and it would be a good excuse for a different box. Its not exactly fun when you hit the $hit and you have to crank the crap outta the wheel to get it straightend out.

    hahaha 16:1 quick ratio? Try 12:1, which was in some of 1980's Camaro's, and slightly higher in the F41 equipped G-bodies (Cutlass, Monte, etc)

    I believe truck boxes are specific though, I believe the pitman arm, and thus the shaft its on, are different. Don't quote me on that, but I believe it to be true.

    Quick ratio is probably not a good idea in a vehicle that is not equipped to handle abrupt steering changes.

    Since your wanting to do the crossover steering anyway you will need to change the sector shaft or buy a new 2wd box. So you can upgrade to the AGR box and pump. I really like my set up.

    I'd do the cross over steering/AGR mod if it were me.

    Well there were 2 different ratio boxes available on the trucks. Now my 79 has the quick but I'm not sure what the actual ratio is. It's about 3.5 turns lock to lock. My 75 has the slow box with about 5 turns lock to lock. BIG difference and I have recently found a faster box to go on the 75. There are differences that may make the swap from a camaro Box impossible. THe pitman arm being idexed different is the firts major. Not sure if the bolt patern to the frame is the same.
    Now one thing I did notice is that a good bit of the sloppy feeling I had in my 75 is not the box it was the frame flexing. The ORD Steering box made a HUGE difference in the truck, it cured some bump steer and it cured the hanging the right tire and not being able to straighten the wheels issue. The difference was amazing.

    Hey Grim, talk to me about this ORD steering box brace. I'm looking at that for the next upgrade. Have a little pull to the right and sometime a lot but never to the left. Water, snow, mud whatever will cause it to pull. Noticed when I get into a flex situation, the steering feels "spongy" to the right and a little to the left. Will this resolve some of this? Already been through the front end (balls joints, tie rods, wheel bearings, etc).

    It will solve a good bit. Especialy help when flexed. I can flex with the best of them and I was always jamming the right wheel and having to back up to get it to turn. Almost never happens anymore. I can't remember it happening since I installed to be quite honest. Took a lot of bump steer out as well. If you want to flip have somebody saw the steering wheel back and forth while you watch the steering box on the frame. LOTS of frame flex going on. It gets rid of almost all of that. The truck feels much better on both the street and the trail. I'm so impressed that I have concidered it form my wifes bone stock 79 that doesn't see the trail. It made that much difference on the street. http://grimsk5s.coloradok5.com/

    Who has AGR's web address or e-mail address. I need to ask them a couple of questions about the performance of my steering box.
