Currently I have a 2" body lift, and I was wondering could I take this out, and cut the blocks down to 1" and reinstall them? I'm not partial to the body lift, and 1" would be plenty for me.
Yeah, I have a motorized band saw, usually cut steel with it, but it would go through these pucks in seconds. I believe they're made of some sort of hard plastic, maybe even fiberglass, but I doubt the latter.
If you know a machinist or somebody with a lathe you can easily do it there and they will all be perfectly straight and even. A saw and a sander to clean them up works too, it just takes more time. Run a threading die backwards onto each bolt and cut it to length and chamfer the ends a little, then when you back the die back off it will clean up the threads where you cut it. New bolts are really cheap though.
