Real quick does anyone know if the 7700 brake calipers will fit on a 4wd supercrew? Im guessing no, but if by some random chance, they would, i would like to replace mine now so i would rather upgrade if i can.

 

As far as I know, its not an upgrade. They're all the same. But, I could be wrong. Chck part numbers at a dealer or something like that to see if they cross over.

 

On Napa and autozones sites both they list different part numbers for both calipers and they both say specifically for use with 7700lb trucks.

I wonder if there is a difference. I thought maybe they were thicker rotors that were used. IDK though. Thought maybe somebody had tried it and could comment.

 

If you want a brake upgrade, I think one of the aftermarket setups would be a much better choice.
