Lowering Shackle Problems!

So I got my mcgauphy's 2" shackles today and they look awesome, I was real excited about puttin them on. So for the past week I'd been spraying wd-40 on the shackle bolts on both sides, well today I was able to get the nuts taken off on the first side I tried (only tried the one side), but I couldn't get the bottom bolt to budge. I had jackstands under the leafspring where it connects in the front on the frame, and had a jack under the shock to lift and relieve pressure on that side. I put an impact on the bolt head (600 ft/lb) and hit it with all it had and still nothing, so if anyone can help me please do!!!!

Are the lower ones the style where the nuts are welded to the frame and you need to loosen the bolt?

Use some heat on it if you can. Ether heat the nut up then use the impact or if it is a bolt heat the head up if that is all you have.

Sawzall it off and get a new bolt and nut.

I like your thinking Greg. :lol:

Just an update...I got the passenger side off and got the new shackle on and then I went back to the driver's side and ended up getting the bolt loose, but it wouldn't come out so I cut the end off and tried to pound it out but it ended up flattening a little bit, so now I can't turn the head of the bolt anymore. I'm going to try pounding it back in and grinding down the part that flattened. If I can't budge it I will try to use a sawzall and cut it off and pry the old shackle out.
