How to tell if Heavy Duty option for FT 3" Ultimate
A week late but I jsut got home with the kit. 
So I asked for and I am told I received, but having just laid out the $$$$ how do I know for sure I have the heavy duty springs vs the standard springs for the lift?
Basic question I know but I want to make sure before I start into this, that I have what I expect. No where to I see documentation on the difference in either part numbers between the two options .
The kit I have is FTS7143
Thanks for the help.
