Silverado 2500 hd vs 3500 hd difference

Recommended Posts

I’m looking at 2017-19 Crew cab short bed duramax trucks what is the difference between the 3/4 ton and 1 ton srw? From what I’ve read the 1 tons have overload springs on the rear axle and 18” wheels is that the only difference between the two and the increase in payload and gvwr?

Front torsion has a different part number. I’m pretty sure 1 ton came in 20” wheels as well in srw.

Badging is different as well.

I believe the 1 ton also has a larger rear axle, but I could be wrong.

i think 2500 gas trucks get a smaller rear, 2500 diesels and all 3500s get the bigger rear.

What is your intended use case?  

 

If its a diesel engine to tow, go with a 1 ton for the maximum possible amount of payload, especially with a big trailer or 5th wheel.  2500hd is hampered quite a bit with the diesel with payloads as low as 2100-2200lbs on a loaded up crew cab.  1 ton you will see payloads 2900-3500lbs crew cab diesel depending on trim.  

 

If you aren't towing big but still looking diesel, a 2500 will do it for you. 

 

One VERY important thing to look for on a 1 ton is the GVWR.  They did have the option to de-rate the GVWR on them to 10,000lbs.  It cuts the max payload a LOT, back down to 2500hd levels and was an option for "legal" reasons for businesses and DOT rules.

Correct.  10.5" on gas 2500hd, all diesel and gas 1 ton use the 11.5" axle.

1 tons got only 18" wheels on SRW.  The wheel/tire package offered the most payload capacity for the ratings of the 1 tons.  2500hd got 17, 18 and 20 inch options.

Not sure what all that means.

But the 2017 LTZ 3500 SRW had the same chrome star wheels as my 2017 LT C/S when I bought it in 2016. It was really nice brownish gray color.

Maybe they were Dealer installed?

Yea, someone must have put them on it because they wanted 20"s.  The tires are rated for less weight that GM used.  17 inch and 20 inch were a 121 load index tire, the 18 inch was a 124 load index.  The load carrying ability of the 18 inch tire is hundreds of pounds higher per tire, hence why 1 tons only were built with 18 inch wheels.  On the new 2020+up, its 18 inch or 20 inch as the tires they picked for both are 125 and 126 load index.
