    I was hoping that I could get some suggestions on a good way to move the front axle forward in my K5, as this is not something I have researched.

    What I and some others have done is re drill the leaf spring and move the center pin. Its pretty easy on a drill press. I moved mine forward 1.5" this way.

    There are several ways to do this.
    1. Re-drill center pins on springs.
    2. Use plates from M.O.R.E. to move front axle forward 1" or 1.5". They are 3/8" tall.
    3. Use Zero Rates from ORD to move axle 1" or 1.5". They are 1" tall.
    4. Order custom springs with center pin at any location.

    You could also re-drill the perch and spring plate...

    I made offset plates (like the ones already mentioned) to move mine forward 2".

    Hey Russ

    Do you have any pics of the plates you made? Also what kind of steel did you use, measurements and such.

    Thanks

    It is not hard to do, but sometimes I would rather pay someone $20 and not have to mess with it. /forums/images/graemlins/tongue.gif

    Nothing very interesting. Just 4 plates, cut to size, drill 2 holes in each, countersink one, spot weld a pin in the other. They are very similar to those sold by various people. Here is a pic before they were completely finished. Looks like I didn’t take one after they were completely done but this shows pretty much everything except the finish grind on the belt sander.

    Does moving the axle forward mess with the steering geometry at all? Do you have to do any modifications to the steering arm/pitman arm?

    You can not move the axle very much without changing the drag link. With cross over, it's no problem. If you want to keep a stock config, then it depends on whether you have sufficient adjustment in the drag link. However, this will result in a shorter drag link and compound the standard problem resulting from drooping the driver's side front... I would not recommend it at all…

    Please excuse the stupid question, but what does moving the front axle forward accomplish?

    For me, I wanted 2 things. A better approach angle, and more clearance between the tires and firewall (I *NEEDED* it with 42s and 4" of lift).

    I did this last weekend. i move the axle one inch up bu using some homemade zero rates. The on things i ran in to was the Sway bar had to be removed and the Plates for the Ubolts had to ground out, because there was just a small whole in mine and the top of the center pin would not work with the whole when the ubolts where moved up. it was easy, just took some time. and the heads for my center pins that go into the axle are not the same as the Rear one. so we had to take a bolt and grind down the head to fit. do not forget you will have to change your steering arm if you do not have x-over.
