[QUOTE=redbaron69;3572392]thanks for the info guys. my chevy has leafs and everybody always says " its on a GMC frame" [QUOTE]
So, my understanding is that GMC trucks came from the assembly line with leaves unless they were ordered with coils. Chevys were just the opposite, they came with coils unless ordered with leaves...
The "rule of thumb" is leaves = GMC, coils = Chevy however, there is always an exception to every rule...
