Did you notice anything different after the additional inch? Maybe I can do some sweet shackles like @Deuling did.I thought so, I ran the hanger in the 56” location on my first frame before deciding to move it back an inch on the rebuild.

Hmmm, I'm assuming you cycled the springs?Yes I had a shackle angle that allowed more bump travel. Here’s a photo AFTER I moved it back an inch. This is with an empty bed btw

Rookie.Yep, on the trail through the rocks![]()
It wouldn't be to hard to cycle them before I go Edward scissorhands on it if needed. The rest of the truck has what's more?Does anyone know how much travel these springs have? Curious what length shocks I need, trying for a cheap way to get by before I do a custom set of springs or link it. Who knows maybe I will be happy with these and keep them. I'm wanting to set the bump numbers up the same as the front links if not more in the rear if the spacing is good.
The fox shocks are 12 inches, sounds like these can pull more.I’m not sure what the exact travel numbers are but I use every bit of a 14” inboarded without bumps or limit straps. IIRC Adam is using fox shocks off a ferd with bumps, I’d take a closer look at his setup.

I think @jekquistk5 is running these springs, maybe Jesse has some idea.
Do you have it bumping at a flat spring? I was hoping to get close to 14 inches but it sounds like wishful thinking.Yup running the ford 57's as well. They pull 11.5" of travel with a longer shackle than stock. They have settled a bit on me, so I'll be going to like a 6" shackle and that should help. They flat out work awesome with my 12" ads.

Yes, but how do I regain the lift I wonder how the lift springs work for travel numbers? I eventually want to go back to a tension style shackle.Yup running the ford 57's as well.

If you are going with the 56's or even 57's, consider something before you finish the project.
"Could I benefit from moving my axle back 4 inches?"
I did the the shackle flip, 56s and longer drive shaft years ago. Not until recently did I flip the springs around and gained 4" of wheelbase. That of course meant a new tubed driveshaft and some shock location work. Wish I had done it to begin with.
@skunked and @Babaganoosh would say no but they aren't running Blazer wheelbases.
food for thought
So what's ideal for axle location? Having it 5" back? Probably going to run 57's and trying to get an idea if having to move the axle forward or back at all is going to be necessary.The center pin is not in the same place on 57"s vs 56"s. So also take that into thought. The bolt is 1" forward of the stock 56" location. So if you switch it around it'll be 5" back instead of 4.
