Coil spring helper leaf.
I pulled an HO72 4:10 diff out of a chassis with just a 67-70 bumper on it for my 55 dually. It had the Chevy coils with a leaf helper. What's ths scoop on these?

Re: Coil spring helper leaf.
They're a factory option. It should be listed on the truck's SPID.

Re: Coil spring helper leaf.
I have a 71 C/20 with those from the factory. I use the pickup for one thing bringing in firewood. It always amazes me just how much the truck can carry. I have had wood stacked up three feet over the cab roof with little effect. Never on road just my property.

My 72 Cheyenne Super C20 has them on it. The SPID shows them as an Auxiliary Spring 1G6010.
