what about the even bigger 3500 caliper, will it work?

 

Was doing some looking and it looks like the HD 2500 and 3500 calipers are the same so you should be fine.

Here is a link to a site with a lot of good info for our trucks

are those 8800 calipers still workin? i want to put them on my 97 1500 but have heard that the rotor may be too thin for that caliper. i know the '01 1500 has a thicker rotor than the 99 and below. what year rotors do u have?

 

if i put the 86 mm 8800lb gvw caliper on vs the 80mm 7500lb gvw caliper would i need to swap in the 8800 lb master cylinder? I noticed that the 1500 and 7500lb gvw 2500 have the same master cylinder, but the 8800lb gvw 2500 and 3500 have a different master cylinder. brake boosters are the same tho. my current calipers have 75mm piston

 

I know of a few people that put the 8800 calipers on without a problem, another thing about the rotor sizes is that the 2500 and 3500 both run the same thickness rotor, I have not had a problem with my rotor being to thin so you shouldnt have to worry about that.

 

will also need 8 lug wheels if your truck is a half-ton

 

I posted earlier in this thread and just want to update. I have since installed the 2500 calipers and the autozone c-max pads along with russell steel braided brake lines, napa premium rotors and I already had the 1 ton chev wheel cylinders and it all works together really good. not to touchy, not to much pedal travel but just a nice progressive brake. if you are in the rain you don't have to worry about accidentally locking up ( which I had with only the 1 ton rears ) and if you have to get on the binders hard they will melt your face. however I am running 265/85/16's right now but when I do get bigger rims and tires I know the brakes are up for it. all direct bolt on.

 

What is this in reference too?

 

from what i can tell the 7500 lb gvw 2500 runs different rotors from the 8800 lb gvw 2500 and 3500 becuz they hav different part #'s on autozone.com and the dimensions vary as well. also, the HD 2500/3500 master cylinder (LD 2500 is same as 1500) appears that it would be a direct bolt on... would i benefit from installing this master cylinder? the bore size on the 1500 and 3500 master cylinder are both 1 1/4". lastly, would i benefit from swapping to '01 rotors or would they work better with the 3500 calipers?

 

Yeah the LD 2500 is the same thickness as the 1500 rotor

Thats above my knowledge for the master cylinder as I do not know the differences between the 2 and I do not know about the rotors my truck is 2wd and I cant swap to newer rotors so maybe someone with more knowledge on this can help you
