    I was wondering if anyone had redrilled there front springpacks to move the axle forward. If you have is there any problems that you have had from doing this?

    Have you considered using ORD's 'zero rate add-a-leaf' for this? May be easier, but it'll lift the front an inch.

    Good quality sharp bits, some cutting oil and low speed...

    I drilled 10 leaf springs in about an hour with a 1/2" drill. It was much easier than I thought it would be, although the bits did need somewhat frequent sharpening.

    I was told as long as the new and old holes are still between the U-bolts that it shouldn't be a problem. I drilled the new holes 1.5" from the old holes.

    Not to mention having to move the hole in the spring mounting plate when you use the ORD ones. I saw Keiths rear ones and cant see makeing a hole in the weakest spot of the cast perch. Has anybody used these on the front?

    it would not bother me a bit to use them in the back. Im just not sure about the front. I know alot of people use them on the front with no problem. I would just rather redril the springs.
