Not sure if anybody brought this up yet, but I was looking at pictures from the reveal the other night and noticed something odd about the LT Trailboss. The axle looks quite a bit different from the normal GM 12-bolt 9.5"/9.75" AAM axle on the K2 trucks. The other 2019 Silverado trucks at the show had a standard 9.5"/9.75" axle. I've only been able to find two pictures of this axle so far. If anybody else can find more pictures of the LT Trailboss's rear axle, post them up. So far what I've noticed is: The diff cover has a square embossed area just below the filler plug. The pinion flange looks different. There are also blocks or bosses on this particular casting that aren't on other versions of the current AAM 9.5". They're on either side of the housing, above and below the area where the axle tubes are riveted on. The truss ribs are different. This axle housing appears to be a much beefier compared the the standard 9.5". There also appears to be a wiring harness visible above the axle housing. There also appears to be a metal bracket of some sort on top. Is this evidence that the Trailboss will have an E-locker? LT Trailboss: Standard GM 12-bolt 9.5":
