Yes.. where's JGW.
For the sake of answering the question since it'll be in right section..soon.
For pocket flares, any oversized ones that sit higher than stock either won't work at all or might work with trimming/mods. ie: bushwacker pocket style.
So if you want clearance + snorkel, you'll be better off with flat fender, if you want something to cover up wider tires, use either flat fender or fender spacer/extender.
