I was playing around with the idea of swapping springs in my Raider. I may go with a little longer spring to get some articulation out of it.

Chevy 56s are not centered, they have a offset center pin. 52s are centered.

Here are some stats of common spring swaps with Blazers and other ChevyÆs. Maybe one of these would work.


Stock Blazer front springs-
23 ¢ to center pin to 23 ¢ (47ö total), 2.5ö wide, 1- 7/16 to 1 15/16 thick (3-4 leaves)
Chevy 52ö springs, found on the back of any K5 blazer-
26ö to center pin to 26ö (52ö), 2.5ö wide, 2 1/16 thick (4 leaves)
Dodge 52ö springs, found on Ramchargers and ¢ T dodges-
24ö to center pin to 28ö (52ö), 2.5ö wide, 1 11/16 thick, usually 4 leaves
Chevy 56ö springs, found on the back of most Suburbans and ¥ T trucks-(some Burbs also have 52s)
26ö to center pin to 30ö (56ö), 2.5 wide, 2 9/16 thick, usually 6 leaves + helper
Ford 57ö springs, found on the back of 2wd F150s (mid 80s to 96)
25ö to center pin to 32ö (57ö), 2.5ö wide, 1 ¥ thick, usually 4 to 5 leaves
Ford 57ö springs, found on the back of F150s (97 later)
26 ¢ ö to center pin to 32ö (57ö), 2.5ö wide, 1 ¥ thick, usually 3 leaves
Chevy 63ö springs, found on 88 later 3/4t pickups-
32ö to center pin to 32ö (64ö actual), 2.5 wide, 3 ? thick, usually 5 leaves

Alot of the above spring packs have + or - leaves in the pack. But on average these are what I've come across.

I ended up putting longer springs front and rear on my K5. 52ös upfront and 56ös upfront. Then I decided I wanted even more articulation so I went with hybrid Ford 57ös up front and back. I may go with 63ös in the back, but I am still playing with the 57s.

Now I just have prep the SR axle for new springs instead of coils then I'll see what to put under the Raider. <img src="/forums/images/graemlins/smile.gif" alt="" />
