2007.5 Chevy Silverado 2500HD 4x4

Anyone have any recommended lifts that won't compromise ride quality? (or may even improve from where I am at now)

Tires rub some and the previous owner has a leveling kit on it and it seems there's not much room for movement, can really tell when I hit some of the bigger bumps.

Not really looking for major lift, just something that will improve ride quality and get rid of the rubbing.... without raising it too much.

raising it will not improve your ride quality.
if the truck has decent mileage on it getting new shocks and better tires that wont ride as harsh are your best bet.
but at the end of the day its still a truck it will not ride like a car

Weird how my 6 " suspension lift on 37s rides way way better than stock.

I was going to say lol.

Explain to me how a quality long arm kit won't ride nicer than stock?

depends on what you do for shocks and springs more than actual lift components.....

Precisely. Rough country vs bilstein

Truck has 220k was planning on buying a kit that came with shocks.. was reading about a Zone Offroad 3 inch lift via UCA but I think I'm going to go with a 6.

Any recommendations that some of you own and really like the quality?

get w/e u want for actual lift components, but get bilstiens for shocks and i like devers for springs

Zone is garbage .. and you said you wanted a mild lift to prevent tires rubbing, why the hell are you considering a 6 inch lift?
This has bad written all over it.
