How to identify Over Load spring

[DirtMcGirt]

I’m looking at getting a lift kit for my 96’ C3500 SRW. I don’t know how to identify if I have an over load spring on my truck. I dug some in the forums but couldn’t find a clear answer on how to identify it.

All the ones I know of are the short flat one on the bottom of the stack, but I don't know for a fact on these trucks.

1-ton overloads are on top, its a 3-spring pack that are normally floating when unloaded then hit stoppers on the frame when loaded

They look like this. The GMT400 3500 SRW didn't come with them as far as I know. This is a Ford, but you get the idea.

'88 C3500 SRW. The overload is the bottom spring.

K3500 overload springs, maybe a dually only option?

Yes, a dually-only option. I thought the standard DRW (GVWR = 10k) only had a single overload leaf above the block? The Cab & Chassis (GVWR=12k) also had them, but a 3 leaf above the block? @Supercharged111 swapped some C&C into his dually.

I wouldn't expect OP to have them on his 3500 SRW...

I have the multi-leaf pack on my 1997 Dually.

This is correct.

Got a pic? I wonder if you have 800 or 900 springs swapped in.
