Do Suburbans have 52 or 56 inch rear springs?

[CheyenneKid]

Are the spring rates the same as Blazer springs for the 52 inch versions? I have an '88 with a broken rear leaf. Thanks.

 

[dleroy43]

mine are 56"s

depends on the year i think
the earlier one had 52's and later had 56's,,,i think anyways

1/2ton is 52s, i duno bout 3/4ton. just get leafs for a 1/2ton and ull be ok

 

[4xcrazy]

that can't be entirely correct either,,,cause mine is a 1/2 ton, and has 56" springs,,,,

You probably aren't inquiring about Suburbans as old as mine, but I have 52's out back.

my 90 Sub has 56" rear springs and it is a 1/2 ton

I'm not sure what year they changed, but the later ones have 56's, up until the IFS style came out. My '90 1500 has 56's out back, but they were "upgraded" when I yanked out the stockers and put in a set from a 3/4-ton pickup.

The best way to tell

The 78 2wd I had were 52's.

It's pretty wet out there right now on the east coast! That's what I'll do.

the newer sfa burbans have 56s? thats news to me. thats more than i learned at school today

Got my 56's rear springs from the junk yard out of a 91 V1500 (1/2 ton sfa suburban 4x4), much better way to go then 3/4 ton leaves that you have to remove leaves out to get them to flex.

I measured them! My '88 sub, factory tow package, has 52" springs. Now I need to come up with springs to replace them with.
