Default 63" 1/2-Ton Chevy leaf spring swap mod.

Ok, I can't remember if this was on this forum or one of the many others that I have an account on… But i'm pretty sure it was on here. I remember seeing a thread by a guy with an old-school red 4-runner that was talking about putting 63" leaf springs from a 1-Ton Chevy on his 4-runner.

Anyways, the one-ton springs are overkill. So 1/2-ton springs is what it's gonna be. All I want to know is, what the new spacing needs to be for the leaf spring hangers on the frame. I can't remember what that distance was.

This spring I'd like to try and find a set of those springs and put them on my '03 Tacoma.

Anyone have any idea?

Pirate4x4 has tons of info on this conversion, check there. You also don't want to use 1 ton leafs, they're way, way, too stiff. People use 1/2 ton leafs. I used 57" Dodge 1/2 ton leafs with the overload leaf removed on my son's 4Runner. It didn't lift it enough compared to the front SAS, so I have to add another leaf back in, but they work great.

If chevy springs are what you are looking for, you might try Chevy Truck Parts out in Hudson. They have a huge yard of the older Chevys and if you call them and tell them what you are looking for, they can search the yard and probably pull them for you too. I was just out there on Friday, he has an old Chevy COE cab that would make an awesome project!

I did some searching and found this. I thought i'd go ahead and post it for future reference, in case anyone is interested. It contains 99.9% of the needed info, I think.

I like the Pirate4x4.com FAQ the best. I would not use the double shackles though. The stock Chevy shackles work best and lowering shackles will give additional lift.

There are plenty of 1/2 ton Chevy's you can get springs from yourself at the Pull and Pay yards for about $25 each.

This is still one of the best things ever done on my 4Runner, I don't think one could imagine how superior these springs work until they try them. I have done this twice now, I'd be happy to get any dimensions for you, if needed.

i did it to my 84 hilux
pirate has a lot of info
the rear hanger bolt hole needs moved back 4" I just bought a orbit eye shackle hanger from trailgear and welded it behind the oem hanger. and the oem hanger dose not even need to be removed and it makes a perfect 4"
the front hanger bolt hole needs moved 11" forward of the orgional hole (double check that number with pirate ). removal of the oem hanger IS necessary as it hits the leafs.. and you also do not need to use 3/4 ton leafs.. most people use 1/2 ton.
I personally used the 3/4 so that I could still have 3/4 ton load capacity. then I removed the overload leaf, as I only loaded the truck with 3/4 ton one time. ( 3 days after finishing the project) which is how I relized the front hanger needs to be removed..
then as long as you have a shackle flip kit your good.. if not buy one as your going to need new u bolts because your removing your old ones.
REPLACE ALL THE BUSHINGS ON THE 63" SPRINGS before installing on to the truck. its very cheep maintence. and the old bushings are crap.
as for shackles I just used 3/8" thick 6" shackles. and I didn't need any offsets. as I made shure that the rear hanger and front hanger were 63" width..

63" on top old Toyota rear on bottom

Cool guys lets do this. It'll be an extensive amount of work and it sounds like 2-3 vehicles. Let get a parts list together and cost so we can plan accordingly. Also we should set up a field trip to ye olde scrap yard. A good old Rising Sun sanctioned pick and pull event!
