Are there any good kits out there that would be worth doing a rear 14bolt disc
I have never done a rear disc conversion, or driven one, but the ones I see and hear about don't impress me much. If I were going to put discs on the back of my truck, I'd want to grab a GMT-800 14 bolt and move the spring perches and shock mounts. The GMT-800s have factory discs.
I found a 97HD chassis with a rear Disc DRW 14bolt, would that stuff bolt to the SRW axle,
The only 97HD that I know of is the 3500HD which shares the cab with the GMT-400 pickups, but the chassis is completely different. It should be a Dana 80 axle, and I doubt anything would swap. If you are talking about a C or K 3500 pickup, it's not going to have factory rear discs.
what about the front brakes, they have to be bigger than the 2500? Any advice out there from the forum would be cool. thanks.
Assuming you're talking about a 4wd 8-lug truck, the calipers, pads, and rotors that are used on the front of the DRW trucks is a direct swap. So that would be the 459 pads instead of the 370 pads, thicker rotors and larger diameter pistons in the calipers. I considered swapping the larger DRW brake cylinders into the rear, but apparently the lines/fittings are different, and since I already have new wheel cylinders I probably won't bother messing with trying to swap the larger cylinders in.
If you have a 2wd truck, look at the 2002 1-ton vans for rotors... maybe a couple of years earlier. The pads and calipers would be the same as I mentioned before. I don't know that those rotors would work for sure, but I would suspect they would... My truck is a 4x4.
