Making a 2500HD CCSB into a 3500

I was thinking this through a few days ago. Has anyone tried to make their 2500HD CCSB into a true 3500? I am under the assumption that the only thing different between the 2 is an additional spring and 265 tires. Is this fair to say?
With this thought in mind, I was wondering why GM does not offer the CCSB in a 3500? Have any members added the additional spring? Is it even necessary? Any thought appreciated. :thumbsup:

After sifting through the EPC I'm convinced the brakes are different. The pistons in the calipers have different part numbers, I would assume the 3500 ones are larger. It makes sense to me that the higher capacity truck would have a higher capacity braking system.

As to the thought processes of GM...who the *#$& knows? :skep: I've been trying to figure them out for a while now, no dice. You ask if the extra spring is necessary? Does anything that you tow now cause your truck to squat in an undesirable manner? If it does I would add air bags before I added that spring, I would not want to make the unloaded ride any stiffer.

Thanks for the response. I was also thinking about the air bags to supplement the ride height.

Well, you can always get a 2011 3500HD SRW!

I would love to! That would solve all the issues!

The additional springs in the rear, the brakes are a little different, they are 8ft bed. You could do the suspension stuff and not have the truck sag as much, but thats about the extent you can do it. The loss/gain ratio is way to far apart for a guy unless your hauling or towing alot. The stiffness in the ride unloaded will suck balls. Just do the in cab air bag setup and you'l be happy.

According to some the 3500's also have extra bracing in the frames.
