Anybody replace 35” with 37” yet?

And if you off-road your truck with 37s you will find out quickly that you are going to have issues.

Definitely, if you just the tires on I would imagine clearance issues.

Was suprised to see both 35 and 37 Raptor's both have 4.10's at first but then realized its a new 37 that’s 1 lbs heavier.

yes. They both have 4.10. I bet changing the rear end gear for 37s would also require re-programming the 10-speed.

I would order a 37 if they modified the power train to accommodate the larger tires. I get it that there is suspension changes/frame etc but dang. Would have been nice

there are other tweaks the engineering team made for 37 trucks. Breaks , steering etc have been specially tuned for 37’s on a 37 pkg

Too bad these know it all forum engineers didn’t build the truck and Ford screwed the pooch by using 4.10 gears with a 37 inch tire that weighs a whooping 1.17 lbs more per tire totaling 4.68 extra lbs over the 315/70. OMG. 6.00 gears or bust. Ford would have needed to run 4.30s with the 37s to make the effective final drive ratio approx the same as the 315/70s with 4.10s. Hardly something to give a crap about, much less convince yourself you made the right choice by going with 315/70s over 37s. Is it possible to be this dumb and neurotic?

From what I read the brakes are the same through the f150 line. I was specifically referencing the drive train.

Calibration is different in breaking and steering systems

Hardparts are the same though.
