Half ton springs with a coil cut, 2 1/2 drop spindles, a pancake and a z, I wonder what that adds up to in the real world? Because at some point, the really low bagged guys are using the bags to get the frame off the ground, not so much "suspend" the truck, if you get my drift. I guess the question is, how much is too much, with a static drop. I dig your work. I'm considering the 49-52 tank for my behind the axle tank.

It takes 4" to get over large speed-bumps, turn-lane dividers (City Tiddys), & most concrete curbs. Most high-end rod-shops use that 4" marker as a max for static clearance under the vehicle for trouble-free driving.

My dually has 4-5" @ the rails/front x-member & I only worry about high-centering which happens a lot more when it's a 20' chassis (CC LWB).

Measure where you are now & use that 4" number as a benchmark for reference.
