Lowering 1980 gmc sierra
 

Im looking at picking up a 80' Sierra and was wondering if i go 4" in the rear and 2.5" in the front what would be the largest size wheels i would be able to go with? And with those drops will the truck sit level?

I believe 20's with a 40 series tire would be the biggest. And no it wont sit level. It will be a little lower in the front which is what i think looks good. A 2" 6" drop will make it level.

kk thank you
