There was an article in Diesel Power Magazine about a Quad cab/long bed built for some high speed race on asphalt. It was a 4x4, and it was lowered (It was white and it was a cool truck). It had big rims & low profile tires. If you are interested, do a search, you will find it.
Thanx.
FYI

 

I found the champagne colored one on 20" rims... but it was still stock height, and the overall tire size is a little larger than I would like (32").

Couldn't find the white one.

 

Try this link. I think this is the one he was talking about.

my garage door is 6' 9" and i have 2 to 3 inches to spare. i have a 1" block up front and the stock blocks out from under the rear. i also have 35" tires. i would say take the stock rear blocks out and run 245 70's or 265 70's and you should have no issues whatsoever. no way i would cut the stock springs.

 

Pour 4 cubic yards of concrete in the bed, that should do it.

 

I lowered a 2008 3500 4x4 for a buddy. Dont cut the coils. They wont hold the weight of the motor and it will ride very choppy. We went as low as we could in the front because the oilpan clearance with the front diff became a problem. It was about 5-6" in the front and about 7" in hte rear. We run 24" wheels on it. I will try to measure the height of it.

 

Cutting the coils will actually make the spring rate higher... Less coils means less material to flex so the spring gets stiffer.... Higher springs rates mean you need I tighter shock to control the spring or it will just bounce all over the place.

How did you lower the front without cutting coils? I haven't seen any kits, but I haven't looked in over a year.

 

They were custom made from a local spring shop. Took him two tries to get them right.

 

[QUOTE=Ram Daddy;2514602]You could always just do it the old school way ....chop the top

I brought this up once.... since the topic is up again I think you would not have to chop the top exactly but instead take out the bow in it. I think it would look really cool to take about 2 or 3 inches out of the top roof panel on the truck, thus lowering the truck 2 or 3 inches. There would still be a convex shape to the top panel just to a smaller degree. Not sure if this makes sense to anyone but me just thinking out loud.
