This is when I wish I had a camera. Last year on our travels we pulled into a truckstop and there was a extreamly hi lift on a chev and he was towing a older terry. He made up a drop hitch oh at least 14" drop. The top of cab was level with the top of the trailer. looked funny as heck. I didnt see the driver to ask how it handles. I bet it is interesting though.

I know nothing about lifting a truck, But I thought that a "Suspension lift" is putting on a new suspension, shocks tires etc and a "Body lift" is just adding spacers between the frame and the body.
I would think both would affect your center of gravity based on what you did.
I also would think if you do a "Body lift" it would NOT change any of your towing ability because all you did is lift the body from the frame and not change any of the suspension or drive train.
Can anyone clarify this?

On a normal “body Lift” the angle of the drive shaft changes somewhat due to larger tires to go along with the look. You will also change the center of gravity due to the weight of the cab being moved up.

I have a 01 Duramax, I tow a 12k boat, when I had a 2" lift it made the tow hairy in a crosswind condition. I was continually crabbing. Went back to stock and it was much more stable.It is a4x4.

Larger tires will not change the driveshaft angle.

Any good off road shop can do the math and tell you what gear ratio you need to get back to "stock". What I mean is tranny ratio, rear end ratios and tire ratios are combined at the facoty to give you a 1 to 1 ratio, etc. If you put biger tires you change the ratios (1 to 1 1/2, etc). Changing the gears will put it back to stock.
yes, mine should be at 4.27 but I wanted for better towing and in the sand. I went with 4.56s

You don't need a lift kit to tow in the sand, just some good AT tires at 12 psi or so. Do you put a lift kit in the TT too? Noooo, just air the TT down also...

Wow! 3 pages and only 2 people mention the important part about the lift! gears. obviously if your going with a lift your going to bigger tires. and if you do go with a lift make sure the lift springs are rated for the same weight as the factory springs! a slightly larger offset wheel will make up for most of the higher center of gravity.

If you put a lift kit, say 8" or more on a tow vehicle, then had an accident pulling your trailer (or not), the other vehicle is damaged and occupants injured, and it's your fault, does the insurance company bail on you and leave you exposed to loose what cash and equity in investments you may have because you wanted a cool truck? Does your insurance policy have a clause where the policy becomes null and void in the event you "alter any factory designed engine, suspension, frame, etc. components"? I'm not stating this would always be the case. However, I was in the tire and truck accessory business for a few years, and we got out of the business of installing lifts because of this. My garage coverage underwriter pointed it out to me. I didn't want to be another pocket a trial lawyer could dig into. BTW, I've lifted three of my personal vehicles, so I'm not knocking lifts, just wanted to offer my two cents.
