    I'm gathering parts right now. Planning on doing a axle swap come next spring. Will be doing the Springer Suspension at that time also. I'm thinking of also getting the ORD Zero rate add a leafs. Would it do anything for me to move the front axle forward and the rear axle back ??? 6" suspension lift on this truck. I hear /forums/images/graemlins/ears.gif people talking about relocating thier axles, but don't know what it'll do for me. I'm all for doing this build up right the first time so I don't have too keep taking it apart and putting it back together. /forums/images/graemlins/1zhelp.gif

    Relocating the springs would be expensive and time comsuming. You would need to get new driveshafts also and possible do body work. If your truck is going to do some wheeling, extending the wheel base may not improve performance. BUT, if you have a very short wheelbase truck and are putting on a very tall suspension lift; extending the wheelbase would help with driveshaft angles. /forums/images/graemlins/burb.gif

    It's a 76 Blazer K5 with a 6" suspension lift. I mostly just do trails out in the forest. I kinda like the idea of relocating the front axle 1" to 1.5" forward, and the rear axle 1" to 1.5" back. New drive shafts isn't a big issue, I've already done them once, but plan on redoing the rear becouse of a slight vibration. (Would love to get a "High Angle Drivelines" shaft) I'll be swapping in some 3/4 Ton axles, and going with the Springer Suspension in the rear. Now I'm thinking of also adding http://www.offroaddesign.com/catalog/Zero%20Rates.htm to relocate the axles. I also like the idea of another 1" of higth. For a total of 7" of suspension lift.

    Are you doing crossover? I seem to remember reading that you couldn't move the front up w/o doing crossover. I could be wrong though. Are your axle's centered in your wheel well? I know the rear axle on my 72 is WAY forward so I will definately be doing it on the back. Also if you are doing cross over you have to watch that the drag link doesn't hit the spring and limit travel. Hope this helps you out some.

    Wasn't planning on crossover steering at this point. Maybe when I finally find a Dana 60 at a price I can aford. I don't think you have to go to crossover to move the front axle forwad, but I could be wrong.

    No, you don't have to go crossover to move the front forward. But the drag link will have to be shortened to compensate, I think Avalanches steering arms are the answer to that problem though, if you wanna check those out.

    Relocating the front 1"-1.5" forward will help you run and clear larger tires with less lift and trimming as well as help your approach angle. All good things.

    Relocating the rear I would do so the tire is centered in the wheelwell when stuffed. A lot of shackle flip kits inadvertantly move the axle forward in relation to the wheel opening. If you open the wheel well up and move the axle back a couple of inches you'll make the departure angle better.

    Oh yeah...one drawback is you'll decrease break-over a little. Prolly not enough to worry about though.

    OK, mentally imagine your truck from the side.
    Also, visualize yout transfer case (usually the lowest thing in the middle of your truck.)
    Draw a line from the bottom of the front and rear tire to the bottom of the tcase. It should look like a wide upside down V.
    That angle is your breakover angle.
    What he was saying, in brief, is that you are slightly more likely to high center.

    Okay, that makes sence. I guess alot of y'all get more extream wheeling your rig's then I do. I may not get as wild as y'all, but want my K5 to be able to handle alot more then I'll put it through. I have always built every vichile to be able to handle more (dare I say) abuce then I'll give it. /forums/images/graemlins/thumb.gif

    You don't HAVE to do crossover when moving the front axle forward, but after shortening the draglink you'll probably WISH you had!

    Mine had miserable bumpsteer with the cutdown draglink, but is just fantastic with crossover steering. You might be able to tame the bumpsteer with a front swaybar (which I did as an interim fix) but it's still not very fun driving down the highway....

    Hey Greg,
    I am doing the ORD 1" zero rates next week (as well as adding a TH350). My 35's are rubbing on the front "fang" (which I am cutting off this week), and on the front of the rear wheel well. I figure I will move the rear axle back 1", plus the added 1" of lift should keep things from rubbing. I hadn't thought about moving the front forward.. should I? I have a drop drag link, so trimming is not a real option.
    I would love to run a set of those 37" hummer tires on 8" rims, maybe with the 1" zero rates and a one inch body lift I can squeak them under?

    Dylan,

    You might find that 1.5" offset on the rear is closer to "perfect"...I moved mine back a full 2" and that may be slightly more than I needed to do.

    On the front axle, you really need to evaluate how things are looking now. If your springs are soft enough, you will eventually find your tires rubbing on the REAR part of the front fenders....that's the real motivation to get the axle forward.

    If you can do some flexing now to see how close you are to rubbing there, you can assess whether it will be worth the trouble to move the axle and deal with the steering problems.
