Where do the HD silverados get their height? Is it body lift, or just from the beefier suspension?

 

built in 2" body lift into the frame to accomodate the Allison Tranny

 

That's what I thought.... Now what problems do I run into with a body lift?

 

So you're saying that HD's are 4.5" taller from the factory than a z71? Not trying to be a dick, but that isn't correct.

They don't have a "build in body lift". Hence why when you buy a 3" HD body lift there aren't already pucks in there.

They are about 2-2.5" taller than a factory z71 because the frame is physically 1.5" taller and because the HD leaf spring pack is beefier.

 

You won't run into any problems with a body lift. My buddy has a 2002 crew cab hd with just a body lift and 315/70/17's and he hasn't had a single problem in 3 years and 75k miles.

 

no no your right, that was wat i meant, a frame lift, im sorry i said body lift. if you measure the frame of a hd compared to a light duty it is as random hero said taller like it has a built in FRAME lift like i meant to say lol. that is so your tranny tunnel aint crushin your tranny... and more reinforcement i would imagine. also as far as suspension goes they do have better springs and such so im sure that would raise it a little to as stated

you would be fine with a body lift

 

Ah ok, no worries. I was kinda like when you said they already had a 2" body lift stuffed under there

 

i have a 3" body lift with a CST 9-11 Suspension Lift on an HD. No problems whatsoever
