Hi,I own a 2007 Chevy Classic, 2500 HD Allison Duramax, 6.6L V8 Turbo, with full tow package, 3.73 rear axel ratio, short bed, extended cab - towing capacity for a 5th wheel/gooseneck is 15,400lb. I am towing 5thwheel and goosneck horse trailer, both around 12,500 GVWR, and have in general no problems. I was still wondering if I can improve safety and stability, and maybe even have a smoother ride with upgrades like:Ride-Rite air bag helper springs?Air Cell load support kit?stronger struts?Added spring leafs?Performance enhacing custom tune like "balck bear"?Anything else recommended?Thanks a lot Sabine

You have an '07 LBZ 6.6 with Allison 6 speed. The dream combo. Don't mess with it. Fuss with your suspension,tires or such, just not the driveline.

Bilstein shocks first. Or second, you could sell it to me!!!

Both do a great job at a reasonable price and easy to install.

Look into Air Lift air bags. I have em on my '05 3500 mainly to help with the road bounce when I pulled a TT. Actually, they helped the ride when not towing too.

Mine is an 2006 LBZ and I'm not touching it EVER! I get 12.0-12.3 mpg towing my 5'er. ENUF said!

Towing ride does improve with airbags. I have the Firestones and the comfort improvement and adjustability works amazingly well. Do not molest the truck with tunes and it will be reliable.

You can put larger tires on it. 265 instead on 245, same as the 2007 3500 came with.

Lots of people use air bags to level the truck, if needed.

I have a 2007 GMC Sierra Classic 2500HD and I did put on the same size tires as a 3500HD.

It will be gone soon.:(

A mild "heavy tow" tune from one of the reputable Duramax EFI live tuners will do wonders. Don't believe all the naysayers who say it will just ruin your truck. Simply not true... If you want to inquire more head over to the Duramax forum.
