Maybe HD for a higher gwvr ?
Or HD for a big block
I know in 1500/10 coils, the HD are for the off chance the half ton had a big block...
They're basically 3/4 ton coils, but I think slightly smaller
I have HD coils in the front of my r1500 burb... they're still 1/2 ton, but HD

Possibly the GVW? Some were 10k others 11k. Had a couple 11K trucks but they were later model. One was a small block. The big block 11K truck had an air bag inside the front coil from the factory.
