Big Ten?

What years was this name used? What differentiated it from a typical 1/2 ton truck? Was it used on c10 and k10 trucks, or c10's only? Did GMC use this name?

Just a curiosity -- how tacky would it be to put a "big 20" sticker on a "c6p"-equipped 3/4-ton truck? It's sorta' the same thing.

Re: Big Ten?

Well a C20 is twice as good as a C10. 10x2=20.

So I would do it, and if you get some 70's goodness stickers it will look right.

Re: Big Ten?

Big 10's were C-10, no K's, C-15 GMC's were called Heavy Half. It was a heavier suspension package and gave you a higher GVWR rating. It was available from '76 through '80.

Re: Big Ten?

Were bigger rear brakes part of the Big 10/Heavy Half option? I have run into different rear brakes on C10s from backing plate-out. The bigger brake backing plates set inward toward the leaf spring more. Not sure on diameter, but wider for sure

It appears they did get bigger brakes on the BIG 10's per this screenshot of the 1978 Vehicle Info Packet on the GM Heritage site
