Hey guys let's say I have a 76 blazer frame currently with 10in springs and 40's. Wanting 44's I picked up a 80 chevy dually one ton for a axles. What is my best option for drivability and flex. I'm sure I have to shackle flip rear but what springs should I try and find? Length width arc? Thanks for any input.

What are you planning to do with your rig? There is ALOT of options out there for the full size gm trucks. I'm in the middle of a build right now that consists of stock 52" springs out back with a 4" shackle flip and 6" udsr shackles. Out front i have stock 52" rear springs with 7.25" long shackles, 15" travel pro comp es9000's and modified f-250 shock towers. This setup overall gave me right around 4-5 inch's of lift and I clear 37's pretty easily with very little trimming and it has LARGE amounts of flex. The only negative is that it has taken a lot of work to make it streetable again. Also with any type of flexy spring you absolutely must have a crossover steering setup. The other option that i've heard of but have no experience with is the TC EZ-Ride springs which will require considerably less work since they are just a bolt on install but not quite as flexy as the 52's.

Yeah, kinda depends how you plan to use the rig. Rocks, mud, street, everything?

Yes I'd like to dive it on the road. I understand I'm not going to be doing road trips but staying in my own lane is a plus.  can I remove leafs from what I have and use shackles and drop brackets? Or are they too stiff still? Have shocks, just going to remount them. thinking I'll need more than 5 inches. How can I load pics from a phone?

Trial and error is gonna be your best friend when it comes to finding how soft you like the suspension. You can try removing a leaf or two depending on how many you have to start with, which i'm gonna guess it's probably 7 leaves since you said 10 inches of lift. Removing leaves will lower it some though. Shackle angle really limits the suspension travel using stock length springs, so you can also move the shackle mounts forward on the frame and use 6" - 7.25" shackles to gain a little more flex while also making the springs act a little softer. This only requires something to cut the rivets off the frame, a hand drill, 7/16" drill bit, 1 7/8" bi-metal hole saw, and eight 7/16" grade 8 bolts and nuts 1 1/2" long.

If you have 10-inch lift springs now you will need to replace them to do the shackle flip in the rear. You can't really take 5 inches of lift from a leaf spring by removing leafs. The spring will be too long an likely bind as it flattens out.
