As someone waiting on their new 37's to come in. I can say I struggle with the known concern that it wont' be as fast as I would have hoped. It won't be as fast as a Raptor with 35s. It won't be as fast as any F-150 Powerboost, and it will be embarrassed by the F-150 Lightning. I keep telling myself.. as an off-road vehicle built for baja running, it's everything anyone would want an OEM car to be (even though I'll never use it for that). Also the higher clearance gives it a better stance IMO and I think the resale for the 37s will be higher too since it supports 37" spares.
If I want to go faster, I'll look at a tune.
Just understand ... larger tires = taller gearing.
Going to 37 inch tires is "nearly" the same as swapping out your 4.1 final drive for a 3.9 final drive R&P.
Going to 37 inch tires is "nearly" the same as reducing ALL 10 of your gear ratios by .025 (or about).
All things make it slower. However if it makes you feel better. The Raptor with 35's has a "theoretical" top speed of 262 MPH. The Raptor with 37's has as theoretical top speed of 277 MPH. So assuming some magical land where the truck doesn't have any drag forces to contend with... you'd win a top speed competition
