Sorry,I just saw your message...As far as Leaf or coil over goes thats probably an easy one... Pros to coil overs are more adjustablity, and in "general" better articulation. The cons 1) LOT harder to set up 2)Much more fabrication,more mounts and Link bars etc, etc,. 3)The biggest drawback its much more expensive. Good leaf springs will flex just as much and Much cheaper & Easier to install. If you are just occasionally wheeling your probably best off w/leaf springs. Especially if your on a budget and have limited resources (people who have some experience that can help you). I do plan on doing a link set-up with either coil overs or air shocks, but mainly just because I want too, not really cuz I need too, Lol. Let me know if you have any other questions, I would be glad to help!! Good Luck,Be Safe and Thank You Very Much for Your Service!!
