Hey i was wondering if any body knows how interchangeable are leaf springs? between front and rear and between different vehicles?

so does that mean i can put those different spring lengths on and get a higher/ lower lift?

 

Pring length and lift are two different things. Generally for a given thickness/stiffness spring, the longer one will flex better than a shorter one. Typically only the main leaf and possibly the 2nd leaf (if military wrapped) will be the full length. The other leaves will typically be shorter in length. The length of the spring has to match with the spring hanger to shackle hanger length on the frame, either the stock mounts or with relocated mounts:
