Customs OEM replacement (lift) leaf springs

Have a 57 panel delivery.
Want to maybe replace the OEM springs with something to lift rear around 2-3".
Looking online I think i come up with ..

• SRI Number:22-231
• OEM Number:3712520
• Width:2 Inches
• Length (A): 26 Inches
• Length (B):26 Inches
• Arc (C):6-3/8 Inches
• Number of Leaves:7
• Pack Thickness (D):2-1/16 Inches
• Capacity:1,150 lbs.
• Front Bushing:Included / TB-7
• Rear Bushing:Included / HEC
• Location:Rear
• Spring Construction:1st Stage 4/291, 2nd Stage 2/291 1/323

Anyone know a 52" spring 2" wide that would likely give and additional 3" arc ? Listed here as 6-3/8" inch.

 

jc whitney used to sell lift springs ,, maybe check with them ,, and spring shops arent really expensive ,they could re arch yours,,

miss you dad

 

Wouldnt re-arching cause them to be shorter in eye to eye length ?

 

See if there is a truck shop in your area that makes springs. They can re-arch your springs to the exact ride height you are wanting.

 

Are Panel trucks considered a 3/4 ton ?

Looks like i can get my existing leafs rearched locally for $450
or I can buy new and have them rearched in MO for around same price.

He was working off these springs...... a bit stronger than the 7 leaf I have now ...... but I wanted to make sure Im not giving him the wrong leafs before I drop $500 .. as that would be on me

I measure 52" (26/26 ) 2" wide on my current panel ....

 

Eaton Spring? Probably will be pricey but I bet they can provide what you want.

 

They made two different versions of the panel truck. The 3100 short wheelbase, 1/2 ton version has 6 lug wheels. The 3800 long wheelbase, 1 ton version has 8 lug wheels.

If yours is a short wheelbase, it's 1/2 ton.

 

Squirrel !! My man.
6 Lug wheels.
You are are walking encyclopedia my friend.....

 

Thanks..but I only know a few chapters, not the whole set!

Standard leaf springs in rear were 7 leaf, heavy duty were 8 leaf. 1100 lbs vs 1350 lbs capacity.

I believe the panels and suburbans all came with heavy duty rear springs. But I'm not sure.

 

If thats a '57 Chevy panel, go here and start looking at leaf spring rates measurements. You may something newer has heavier springs that might work, https://www.gmheritagecenter.com/gm-heritage-archive/vehicle-information-kits.html

 

Thanks all.
Got her welded in ..... seems pretty straight, took her for her first run around the block - rode like a champ even without shocks ..... have a PS leak I need to fix then almost time to get her licenced for the road.

Appreciate the assist.

 

I tell people I know a little bit about a lot of things but not a lot about anything but in Squirrel's case its a lot about damn near everything. JMO
