    What reaends come in the new fullsize Gm p/u with the rear disc brakes? They offer rear discs on 1/2 ton p/us and blazers/yukons correct???

    What rearends are they using on the disc brake equipped trucks?

    On the 1/2 tons they are still using 10-bolts but the ring and pinion is a tad bigger, not sure on the size now, something like 8-3/4. Someone else may know the exact size.

    I wander if itis the 8.875" carrier like the 12 bolt?

    I was thinking of trying to use the factory rear disc rotors for my 12 bolt. I saw a pic once of the new models rear discs and they look like they just slide on the lugs, that would be easy for a rear disc swap if everything will line up ok!

    I'm not 100% sure, but from what I have read the rear axle is a 10-bolt with a 8.6" (versus 8.5") ring gear diameter and a supposedly improved gov-lok.

    I can imagine that trying to source disk brake parts from a new 2000 truck will far exceed the cost of a complete TSM rear disk brake kit.

    Yeah, but if you can find one of these trucks wrecked (like I saw on a flatbed wrecker yesterday), you might be able to get a NEW rear, with discs, for a good price. Hmmmmm...
