The spring came complete from 4wheelparts.com. How can I install them backwards?

Obviously i havent seen your springs but i have seen some that are hard to tell which end goes to the front and which sits in the rear. You have a strange issue. Do you have any pictures?

Put a lift shackle on the lower side & stock shackle on the high side.

FIXED.

That would be the half *** way to fix it. The springs shouldn't be that much different. I'd call/email 4 wheel parts and see what they say

He said "any ideas",I gave him one.Yes,it's 1/2 azzed & was intended to be a smartazz coment as well, but it IS a option.

My first option would be send them back or contact the company he got them from & let them fix the issue.

OP,ditch the blocks.It induces axel wrap/early spring fatigue.

Did you set them side by side and check to see if they were the same before you installed them? The reason that I ask is, that I ordered 3" lift spring packs and when they were delivered and I set them side by side they were not the same. Come to find out after checking them out they sent me spring packs that were built up from 2 different companys and they did not have the same spring rate even though they had the same P/N on them.

The spring bolt that holds the spring leafs together is not on center of the spring, so if he would have installed one backwards the axle would be at one hell of and angle and very noticeable.
