It depends on how much money you have to spend and how long you can have your truck down. I have no problems useing leaf springs infact I'd rather have leaf springs that coil springs. Coil overs are nice but still I perfure leaf springs, I like the fact that my front tires drop forwards insted of back tords me. If anything I would say keep with leaf springs up front and if you want put coil overs in the rear, that would be a kiler setup.
