4 inch zone lift suspension

Hello,
I have a 4 inch Zone Offroad list on my truck and want to upgrade new coilovers in the front instead of the spacers on the truck already and also new leafs in the rear instead of the blocks. The lift was a graduation gift from my dad a few years back and I didn't want to be rude so I happily accepted it even though it wasn't what I wanted to put on my truck. Would I be able to upgrade my suspension without getting a whole new lift? if so any recommendations?

 

New to a lot of this stuff and don't know what my best options would be.

 

Call Zone off-road and see if they offer a extended length coilover . A set of 3” rear leafs plus any items needed $700-1000, front coilovers(extended length) probably another 1000-2000 depending on brand.

 

I believe fox makes coilovers for a 4-6” drop bracket lift. Check with @AccuTune Offroad
