Would this work?? upgrading from 2.5" TF Coils to 4" Rancho Coils
It depends the earlier kits that came with the 2.5 lifts used shocks that worked with that kit all the way up to the 4 inch lift. The newer versions have 2.5 specific shocks that wont work. Your best bet is to call teraflex and ask for the serial number on the shocks that will work with the 4 inch lift and see if they match yours otherwise you'll need new shocks for those coils.
