yukon25008.1 Posted January 15, 2011 Share Posted January 15, 2011 just curious about the difference, ive been looking at 100,s of trucks and just curious the real difference between the 2, especially the frame, i thought i was just and extra leaf and bigger brakes, everyone i see with a 3500 or selling one, always uses that as the biggest point, 1ton, 1ton etc.... i had an 04 f250 diesel and the guy that worked on it said he saw no difference between mine and his fathers 02 f350, so if we sat an 05 sierra 2500hd and an 05 sierra 3500 srw next to eachother whats the difference? Thanks guys Link to comment Share on other sites More sharing options...
newdude Posted January 15, 2011 Share Posted January 15, 2011 The GMT-800 trucks (03/04-07) 3500 srw's came with 16"x7" six spoke steel wheels only, either painted or chrome. GVWR is 9900lbs, and I think use an extra leaf in the rear. Axles should be the same too. None of those trucks could be had with short boxes either. All srw 1-tons were long box. For GMT-900 (07-10), the 3500 trucks got the 3500hd nameplate on them. Only other real difference I think compared to the GMT-800 1-ton srw is you could get the same 17"x7.5" cast aluminum 5 (chevy) or 6 (gmc) spoke wheel. The 2011 GMT-900 trucks follow a similar formula except every single capacity is increased (both 3/4 and 1-ton trucks). Mechanically, the frames are the same, the brakes are the same (drw I believe also, except the process in changing them). The only thing I am not sure of is if all 1-ton trucks get the 11.5" AAM whether they are gas. Anyone else, please feel free to correct me/chime in.

[email protected] Posted January 15, 2011 Share Posted January 15, 2011 As far as the frames between those two models, they're the same. Link to comment Share on other sites More sharing options...
8.1HD/ALLISON Posted January 16, 2011 Share Posted January 16, 2011 +1 on the above. Only thing I have noticed is the gvw and couple extra springs in the rear. Link to comment Share on other sites More sharing options...

Most of the additional GVW comes from the tires. The 3500 came stock with 265 the 2500HD came with 245. That is why the 3500 has the painted steel wheels. The wheels are 7" wide not the 6.5 on the HD. I know many have changed the tiny 245 to 265 even 285 on the 6.5 wheels but tire manufactures specs no wider than 245 on a 6.5 wheel to maintain the tires load ratings.

Diesail Posted January 16, 2011 Share Posted January 16, 2011 Yep, anything with the HD badge has the same frame. The 2500HD gassers use a 10.5" rear, all the dmax's have the 11.5" rear. Link to comment Share on other sites More sharing options...
8.1HD/ALLISON Posted January 16, 2011 Share Posted January 16, 2011 Yep, anything with the HD badge has the same frame. The 2500HD gassers use a 10.5" rear, all the dmax's have the 11.5" rear. Mine is a gasser and it has the 11.5 rear. Course its an 8.1L. I think the 6.0s use the 10.5. Link to comment Share on other sites More sharing options...

Seems I heard the 11.5" only came with the Allison, but I am no expert on the topic that is for sure. Link to comment Share on other sites More sharing options...

[email protected] Posted January 16, 2011 Share Posted January 16, 2011 I believe so, because the dmax that had the 4l80s in them still had the 11.5 Link to comment Share on other sites More sharing options...

[email protected] Posted January 16, 2011 Share Posted January 16, 2011 And with that statement you are true, I was thinking about vans and whatnot I guess. But, here is a good read Here Link to comment Share on other sites More sharing options...
djmercer1 Posted January 16, 2011 Share Posted January 16, 2011 I believe so, because the dmax that had the 4l80s in them still had the 11.5 was it the 4l80 i the vans or the 4l85? our 2 vans (2006s) have the 4l85, i wasnt sur they offered the van with the dmax before 2006.
