Rough country 4 inch or 6 inch

A 6 inch lift on 35s also comes with the mental cost of knowing you have the baddest rig around

Exactly why I love my 6" 35s setup

The difference between Rough Country's 4" and 6" lift kits is the addition of 2" add-a-leafs for the rear for the 6" kit. Both kits come with 4" blocks for the rear and the same brackets to drop the front diff. and suspension 4". To get 6" lift in the rear you install the 2" add-a-leafs and to get 6" lift in the front you need to crank the torsion bars. That's it.

For reference here's my 2 door with Rough Country's 6" lift on '03 Silverado wheels and 33" Nitto Terra Grapplers:

I guess I stand Corrected … I could have swore the only difference in the kits was a 4 inch block on the 4 inch kit and a 5.5 inch block for the 6???

maybe they changed this recently for the 400s?
