How to tell the drop

[Jmann8686]

Bought a 72 C20 a few weeks back. It has been lowered. and I like the stance. I have not looked to much into it as of right now. But i was wondering if there was anyway to tell how much drop as been done to it as it sits right now. The frame has not been notched and there looks to be only about 1-1/2" to maybe 2" of travel before the axle hits the bump stop. Is there anything I can measure or should I look for part numbers. New to the lowered 2wd truck world.

Thanks

What size are the tires? That might help w/estimating drop.

Typically, if there is ~2" between the factory rear bump-stop & the axle on a 1/2 ton truck, I would say it's around 4" drop. If it's a 3/4 ton, the drop could be more since they were taller from the start.

It is a c20 so it’s the 3/4 ton. The tires are 245/75r16

Looked like a 3/4 ton but I didn't want to assume. That tire combo is ~30.5" tall so possibly a 2/4 drop.
