37s v 35s, any hard evidence?

[Honeybadger_Zero]

if this were the case 6100 and TT class trucks wouldn't run 39s/40s. there's no "upgrades" they've simply tuned the same 3.1 Fox to accommodate 37s, this beats having a shock tuner dial it in for you, which is difficult when most are out west.



Yes this is the first OEM truck to receive 37s from the factory. The main reason to run them is ground clearance, you also get the benefit of more sidewall for better control and feel off road. There are more members who can go in depth on why to run 37s for off roading, I just don't want to ramble on about it.

cons to 37s? price to replace, loss of limited headroom when parking in certain areas (I'm on 37s so I use another vehicle) and if you run your truck hard off road you can blow the fender flares clean off lol. I've been on 37s so long I don't even remember the difference, my F350 Temor is on 35s but not even comparable.

There is an upgrade to the suspension with the 37 pkg. the shocks are different from 35” base

Per the Fox video discussing the 3.1s the internals have been tuned for 37s. To say that's an upgrade is misleading.

An upgrade would be running 3.5s or 4.0s with more damping ability, fluid volume, etc vs the 3.1s.

Physical dimensions of shock are different as well as tuning. 37 shock piston rod is 1” over 7/8” as I recall. Either way. Still different and upgraded vs the 35.

Lol the shocks on the 37 truck have a shorter stroke so they need the larger shaft to increase the dampening to give a similar feel to the 35 truck….upgrade!!!!

The seem to be different. Here is engineer discussing. 6 min mark.

I currently have a 37 on order so I'm not trying to downplay. But, I see this as 6 one way, half dozen another... It really should be considered an "upgrade" if you bought a 35 and plan to go to 37's down the road. You basically sacrifice an inch of suspension travel in the 37 package but get thicker pistons.

One of the big things 37s will bring you over 35s is that a "35" normally runs closer to 34.5 or so and a "37" is normally 36.5 or something close and the larger tire rolls over smaller holes and the like easier. One of the main things is that tire size is one of the only ways to get more clearance under the rear diff which you'd be amazed how much 1" makes when on a dirt trail with a high center from tire wear or missing that rock that would have ripped in to the bottom of your center section. Yes rotating mass will hurt acceleration and stopping distance but you should theoretically be able to hold more speed over rougher terrain making up for the loss in agility. If you want to see a real world difference between the two before you can test drive the different gen 3's see if anyone around you can let you ride in any vehicle on 37s and go over some rough stuff and curbs and it's pretty easy to tell why moar bigger is generally moar better when it comes to off-road. I have never once regretted going to 37's but I also re-geared to keep a similar final gear ratio to keep performance up. Just my .02.

Wait a minute! I can take this off-road?

There's a rumor that every gen3 that goes off-road gets recalled so the engineers can look at what the unexpected terrain did to their big ford mustang.

The motivating factor for me is that the truck "looks" like it was built to have the 37's. Since none of us have had the luxury to test them out, I couldn't factor in the more logical data points into my decision making! . Damn you FORD....
