2015 2500 Chevy Silverado Diesel

Get the 3500. Then you won't have to BandAid it later with air bags.

I believe that the Tires/wheels rated for more load in addition to the overload spring. I know my 2014 3500 is so much better than the 2500 that it replaced. I loved my old 2004, 2500 and thought that was all I needed until one of the body mounts broke.

Really enjoying 3500 and I was really surprised that the unloaded ride is about the same as the 2500. Randu

If you can afford it buy the 3500. With the higher ratings this truck is much stronger than the 2500. Hopefully you are getting a diesel! If so that's the icing on the cake.

I had lots of 2500's but since 2011 I have had 3500. Got my 2015 last September.

The 3500 is the same size as the 2500, but higher payload, bigger springs and brakes.

3500 SRW trucks are rare at many dealer ships unlike dozens of choices at the same dealer ship for a same equipped 2500.

Depending on selections some 3500 SRW GM trucks can have payloads in the low to mid 4000s lbs on 7050 RAWR.
The 2500 is the same truck but with a smaller 6200 RAWR (rear spring pack/tires and wheels) on same configured truck with 3000-3200 lb payloads.

My son sold his old '02 Dmax/A and bought a white '15 2500 Chevy Z71 loaded with all the bells and whistles. Beautiful truck and rides better than the wife Impala and in my favorite color.

Thanks therink

You get 700 or more payload rating. My 1 ton SRW has a 11,500 gvwr and payload per the sticker is 3700. The cost is around $700.
Mechanically, I believe only difference is overload spring. What matters to me is the sticker towing a heavy pin fiver.
