Inner rocker choices confusion.

[Art Vandelay]

So I need to replace my rockers but am utterly confused by the 3 choices on AMD (Inner, inner full & inner backing plate) and exactly which I need. Any direction would be GREATLY appreciated.

I'm going to hijack my own post and ask a side bar question. Just to premise I have watched a lot of videos on changing these but nothing on whether or not you need to. Footwells, were the originals just seam sealed to the floor and do these need to be replaced?

Those look pretty rotted out…I would replace them.

Sorry I’m not much help on the rocker question. I only know inner and outer rocker. Not sure what “inner full” refers to!

like to know myself.

Full inners and outer rockers is what you would want to buy to answer your question if you haven't bought anything already. But.

I would be doing floor pan patches. They come with inner rockers or at least a good portion of them. And they make lower cowl footwell patch panels.

I work for AMD as our QC guy and am also involved with R&D, marketing and several other facets of the business. It is definitely confusing, we apologize. We have yet to come up with a better way to label them.

Looking at your pictures, you're definitely going to need some floor patches, these are the more accurate OE style ones:

For the inner rockers, the "full" inner rocker is what you're going to want. It's more like the original and has the little drainage/wiring channel in it:

The "backing plate", some trucks had and some didn't. We have yet to find a rhyme or reason for it, but we wanted to offer it. If you look up under your truck, you should be able to see the outer rockers, the inners and if you have a third ply there, you have the backing plates as well.

You definitely also want to replace those kick panels, they were welded to the floor originally, not just seam sealed and those have rotted quite a bit further up than they used to be.

Thanks for the info! I was planing on purchasing this floor land as it’s full and comes up the seat hump.
