    I want/need to put 42s on the K5. I have 6inch of lift plus what ever a D60 add's to the mix.
    I know most people here are useing 0-rates to move axle forward 1.5 inches.
    I do not want to get any more lift other than what the tire give ya.
    So question is who has moved the pin forward 1.5 by redrilling the springs?
    Also what did it do for your pinion angle? did you need to put a degree shim to
    put it back to where it was before.

    I am not woried about steering because i'm going full hydro in a few weeks.
    I do know this is not the best way to move a axle but kinda running out of cash. I will get some springs made that have the axle pin 1.5 inches forward this summer.


    Let me know what you think

    i worked at a spring shop for almost 1 year. and made lots of springs. dont do that it will weeken the spring. and it is spring steel if you try to drill it it will take a drill with no more than about 200 rpms and lots of pressure. we used a 25ton hole punch to do this. and for vary thick leafs we pre heated it also. some times when doing this the punch would break. the safe way is to do the zero rate. or just move the hangers forward and make longer shackles to compensate for the movement. p.s. most leafs break at the center pin hole anyways.

    he's not talking about drilling the spring pack, he's talking about adding a hole to the spring perch for axle relocation. I did it front and rear on my ff14b/D60 and it works great. IMO, its best to drill 1" offcenter... 1.5" is pushing it and that extra half inch is no big deal anyway.

    lol! i read the post but for some reason where he said "springs" I thought he meant spring perches. doh! Anyway, I wouldn't drill a spring... to much of a PITA for so little benefit. Drilling a spring perch is quick n easy tho and has none of the downside. :)
