If you haven't ordered the fender flares then you may be ok. What you could do is ask RTR if the safari snorkel will fit. They might give you a better answer. Also if it isnt too late to cancel the order for the snorkel i would cancel it. Mishimoto is working on one that would fit. It removes the passenger fender vent and uses that hole for the snorkel. Just some ideas.
The RTR fender flares are on the truck. I sent a message to RTR and haven't head back. I was hoping maybe someone in the community might know if it was a Go or No Go
Looking at that and looking at ARB's website you may have to trim the fender flare or get a different snorkel. I think that fender flare is sticking up a bit too much. Now to have someone who has just the snorkel to do a measurement.
My side rails get in the way. That’s the best I can add to the conversation. There's about an inch between the top of the stock flare and the snorkel.
