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

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.

On the 800 trucks the frames are the same. 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.

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.

The 8.1 came with and without the Allison right? Seems I heard the 11.5" only came with the Allison, but I am no expert on the topic that is for sure.

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.

      J&L OIL SEPARATOR CO

      By Grumpy Bear · Posted

      Just did an injector/HPFP replacement on Pepper at 192,400 miles; close enough to 200K, RIGHT? (If 200K is considered life end and to me it isn't). But hey, to each his own.    Have never run a catch can on this vehicle. Back side of every valve looked like a new valve spray painted semigloss black. Port walls looked 'neat' (all a normal result of passive EGR via VVT) Zero build up even in AFM cylinders. Just color. It uses no measurable oil and never has.    At 155,000 I put her on E-85 and a borescope of the cylinders at plug change showed very clean pistons and valve faces. The replaced injector tips looked new. (It was the pump piston seal that was leaking). Oh well, have six good backups.    Still gets 28 mpg on gas (highway average) and over 20 (highway) on alky. UOA's look good and runs as good now as it did when I bought it. Better in fact.    What improvement would a Catch Can provide this motor?     And given all this I expect that IF I installed one I'd see some water/gas/oil vapor accumulation. Byproducts of normal combustion.   Having said that, IF my motor used an appreciable amount of oil I'd consider it a useful 'crutch' until I had the situation corrected OR if bore polished, until I junked it or rebuilt it to stave off repeated plug fouling.    I'm not telling you what I THINK. But what its DONE.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By Grumpy Bear · Posted

      Love the look. I'm a SCSB lover myself.    Two items. 1.) A spacer changes scrub radius but this also changes when we use wheels of different offsets. A little isn't a big deal. 2.) Steel wheels, alloy wheels all have different thickness. Same effect on the stud and lug nut as a spacer. When hub centric the wheel isn't supported by the stud. It's supported by the hub. The stud just keeps it all together.

      2016 Sierra 5.3L L83 new injectors now runs rich.

      By JAI3 · Posted

      I had a evap sol go bad a couple weeks ago. . I replaced it.  While watching live data at the time I saw I had some cylinder 1 misfires. No MIL but on live data I could see ~50 at startup and about 70 more after an hour a drive all on cyl 1.  I also noticed that the LTFT were -5% to -15% always.  And that bank 2 is always -3% richer than bank 1. Even across all driving modes, city, highway, etc it’s always 3% richer than bank 1. So I start with the misfire. Swapped coil, plug, and plug wires from 1 to 3. No follow. I got an Injector reseal kit, pulled the D/s injector rail, swapped #1 and #3 injectors, resealed them, reinstalled and retested.  The misfire followed to 3. So I ordered and replaced all 8 injectors, spark plugs, and plug wires. Also replaced the 1 time use fuel pipes under the intake manifold.  Injectors that were in the truck since new were  Part # 12668390.  I replaced them with # 12742701 Got from RockAuto. Pretty certain they’re genuine and the correct ones. I called a friend at a parts store who told me “the 12742701 were the correct superseded part # for the originals I was replacing”. So started truck after replacing all that and it’s running -15 - -30 LTFTs. I reset the fuel trims with GDS2 and drove it for a 60 miles trip each way. There have been no changes in the LTFTs.  I checked if the HPFP was leaking into the crankcase. I removed the pvc and watched the trims. No difference.  I checked the alcohol content and it was at 10%  I’m out of ideas here. Truck seems to run great. Just always rich on the fuel trims.  Anyone with any help or ideas would be greatly appreciated.  I ran an injector balance test just for the heck of it and it came back this. I’m confused.  I have gds2 and some other diag tools if anyone knows of anything I should test next.
