Did some checking at the junkyard today and I found a set of springs I think will work. I want to put 56's with a shackle flip on my 70.....the springs I found are off of a 89 3/4 ton with a 14 bolt. Are these 56's and will they fit on my rig? I already have 3/4 ton running gear so will I need the mounting plates of this truck or can I use the ones I already have?

Sounds like greg was using the same springs on the rear with the shackle flip but still don't know if these springs are 52's or 56's. Greg, have any idea how much lift that gave you with those springs and the shackle flip?

1st Gens use the same spring lengths as the later model Blazers, it's a direct swap.

As for lift, a stock spring doesn't add any... :rolleyes:

I swapped a stock original spring for the later model stock spring....the only "lift" I got was from the shackleflip, longer shackle and the slightly taller spring perches I made.

The idea you have is good...those rears are basically free and will flex quite a bit better than the stock 1st Gen ones.

I am a little confused....The springs are off a 89 K2500 long bed pickup. Are these still 52's (Same as my stock blazer) I thought 3/4 tons and 1 tons had 56's.

When using a stock spring and a shackle flip I thought you get 4 inches of lift.:confused:

Why not just measure them???

....and yes, a shackle flip adds about 4". My point was that there is nothing magical about using later model springs. If they are stock, they don't add lift.
 
I was just hoping someone else knew the length before I go roll around in the mud in sub-freezing temperatures taking the springs off the truck. :D
 
by 89 all 3/4 were 56's

in fact if it is a 89 k2500 they should be 64's for as 3/4 tons had already went to the new body style.
 
Thanks guys, I guess I'll have to go back and look for a pre 88 burb or 3/4 ton truck. Anyone happen to know about when they started using 56's. I thought it was mid to early eighties. I'm glad you guys told me before I started pulling them off and finding out they were longer than I wanted. I found another 81 burb but it's a 1/2 ton. Any chance they would be 56's?
 
56's started in the early 70's.

for 56's you have to find a 3/4 ton.
if it's so hard to find 56's then get some ford 57's and a zero rate(to move axle back to where it should be.

Which is it? If there's mud it's isn't below freezing..... :p:
 
Right now it's a mute point......when I woke up this morning there was about three inches of snow and a heavy snow advisory until six this evening!:(

So whats the answer? yes or no?
I have a set of 2nd gen skyjacker 6" lift springs that I was going to use for 74 but i ended up buying a 72 with 6" skyjackers on the front and blocks on the rear. can i use the rears that I have to replace the blocks?
I thought there was a isuse with the centering hole on the 2nd gen springs. For example 1st gen mesure 24" / 28" and 2nd gens are even like 26" / 26" Does this matter?

The rear springs are identical in length from 1st Gen to 2nd Gen..... I've never heard of the spring pin being relocated on later model springs, and I didn't have any issues bolting a set of '89 springs onto my '72.
