i'm looking for some info or a good write-up on 4 or 3-link systems. i'm looking to 4-link my rear on my bronco and 3 or 4 link the front also and would use 6 inch coils to suspend the truck. i'm trying to figure out if i can buy one of those 4-link kits that the lowered air bagged trucks use and just have longer links made when i order it. still kinda in the dark on this subject all help and info needed.
