Improve my suspension
I am looking to improve my suspension when pulling my 15000lb fifth wheel with a 2008 2500HD Chevy Duramax. Any suggestions.

All Gm 3500 trucks come with the 11.5" axle. Even the ones equipped with the 6.0 liter. They have different wheels, different springs and the 11.5" axle instead of the 10.5" on the 2500HD.

What rhagfo said was the 2500 GM rear axle is rated at 9k-10k lbs (not chevy trucks RAWR number).
However all diesel powered 2500/3500 SRW DRW Dodge/Rams and chevy/GMC trucks have the same 11.5" AAM axle which is rated in the 10800-11000 lb range so forget about any rear axle issues with these trucks.
The only difference in the 3500 SRW and the OP 2500 truck is another leaf in the main spring pack and possibly a upper aux over load spring pack. Many 2500 trucks come with the higher rated OEM 18" wheel/tires which is std equipped on the 3500 SRW truck.
In '14 or so the 3500 DRW Ram has the upgraded to a 11.8" AAM axle.
