GMT400's are too except for the 3500HD which are definitely a different animal than the "regular/normal" one tons. The regular one ton is rated at 10K load but the HD is 15K; they have a solid axle up front with leaf springs and a huge full floating axle in back with massive spring packs. Those are rear discs but they are VERY different than the other 400s.
Confirmed!

This was also the Indianapolis 500 edition from No-Mar. You can see the logo under the American flag.
