I am wondering how tall a crew cab duramax is from the ground to the top of the roof with a 6" lift and 35" tires. I have to know if the garage door would be tall enough to get inside with a lift and bigger tires.

Most 6" lifts run 4" blocks in the rear. The reae seems to make the biggest impact on overall can height. My truck is running a 3.5" block in the rear and 5.25" in the front with 315/75R16s. My truck is 81 3/4" tall. The opening on a 7 foot garage door is 82". With many garage doors you can gain and additional inch by removing the trim strip that usually runs across the top of the door opening.

Now that is close

I think I am leaning towards a pro comp lift, does this lift have the smaller blocks in the back like you were explaining?

Man I hate it that the "edit" feature goes away so quickly. Does my first post even make sense?

I have 6" and still running 33's and I measure about 82" but I fit in with about 2-2.5". Can't wait for the 35's, even though they are 2" taller than 33's, the truck should only be 1" higher.

If you are 82" high, and you have 2-2.5" of clearance, then you don't have the standard nominal 7 foot garage door opening. Thts is actually a good thing. I currently have a 8' header on my garage door, but I'll be moving next summer and chances are the house I move into will have only a 7' garage door--which means I'll probably remove the upper trim strip.

what are you guy's measuring top of roof, or top of antena, my 2002 has a On-Star Antena on the roof so that will add 2.5" on the hight of the truck
