Well I finally got my shackles, and we're installing them tomorrow morning.
It's an obs stepside.
Any tips on installing, or is it pretty simple?

Get a Big Fucking Hammer and take out some aggression on the bolt. I had a hell of a time on the passenger side. Drivers one wasn't too bad.

Well, it looks like its going to be a lot harder to do.
It seems the top bolt is put on to where the head has to be cut off or a hole has to be drilled into the frame.
Anyone else have this problem?

Yes. Just raise the truck until your about the frame/bed support and then take the bolt out.

Hey Colyn, can you go into detail about your advice?
I'm still a bit confused.

Support the frame on jackstands.
With the rear axle at full droop, jack it up and inch or so with a floor jack to relieve stress on the shackle.
Remove the bottom bolt. (go ahead and loosen the top one)
Jackup the axle until the top bolt on the shackle is even with the space between the frame and bed. Reach up and pull the bolt out.
Reinstall in reverse order.

I had to loosen my U-bolts at the axle on my NBS, combined with jacks and stands, for what it's worth. Don't know if that makes a darn concerning an OBS though.

I couldn't get the head of the bolt past the frame, it would get wedged between the frame and the bed if I tried to go over the frame, and it wouldn't get low enough while bolted up to get beneath the frame and around the rear hanger. My whole truck was on jacks and I was working alone. It's just what I had to do to clear the frame and rear hanger.

Maybe I missed something at the time? The end result worked out though.

I recommend making 2 cuts above the shackle so that when you lift your axle the shackle bends that lip enough to pass the top bolt over the frame. Makes it way easier IMO.

My bolts were siezed pretty bad when I did mine. I ended up having to cut the bottom bolt (leaving siezed bolt section in the bottom of the stock shackles) and removing the whole leaf pack on both sides. Then using a big fucking hammer and a drift I pounded the top bolt out. The only reason I took the whole leafe pack out is so I could swing the hammer accurately enough without taking the bed off. I didn't have a engine hoist or a few friends to help me remove it. A little tip if you have to do this. on the drivers side front leaf spring bolt. Cut the bolt sticking out the outside of the hanger leaving about 1/8"-1/4" of thread showing outside of the nut, this way you can get the bolt out without messing with the tank, and you can re install it later much easier.

When you put the new shackles in make sure you put the trucks weight on the rear end befor you tighten any of the schackle bolt, it'll sit crocked if you don't. Good luck.
