Man I am in this inner debate of going 37's or staying 35's

if you go 37s, do it right for the peace of mind and full experience

I'm putting this out there and I hope you other gents chime in (and probably correct me)

Without having to change final gear ratio on Raptor (assuming this is something good to do with the larger tires /added unsprung weight), maybe a lighter flywheel can mitigate the dire need for final gear ratio?

A friend did this with his yamaha yxz 1000r buggy, after adding heavier tires, a lighter fly wheel remedied some drop in power loss

Re gear is one of the reasons I did not go with 37’s I know won’t be facing a problem with losing power because of the 10 speed that being said I am still not connived with running the 37’s without changing gears because I don’t air down and of terrain here is mostly soft sand softer than Glamis and with suck terrain and the added weight of the 37’s I won’t have the same power band through tall the gears the same way I do have it now.

So yes 37’s without gears is no for me unless I run them only in summer only and go back to 35’s in winter. And the only advantage I would get is looks not performance.

I can't imagine a lighter flywheel would help much. I ran 37s on my '14. I loved my 37s at first, but nearly every aspect of the behind-the-wheel feel changed at least slightly. There was noticeably less off-the-line power, but it wasn't as bad as I thought. If it were just this, I could have been okay with it. The worst by far was the body roll and harsher ride. Then there was the significant drop in gas mileage. I went from 13.8-13.9 MPG to barely clinging to 12.1-12.2 (again, this was a '14).

Those things altogether wouldn't have been so bad, except these days I am spending all my time on pavement. It just wasn't worth it IMO.

Circling back to the question of regearing. My bias is toward re-gearing in most cases (I should also point it that I do all my own gear installs myself, so drastically cheaper for me to re-gear). I had a late 80s full-size K5 Blazer with 38.5" Superswamper TSL's and I ran 5.13 gears in that and loved it! When l lifted and installed 35's on my '05 Silverado I re-geared from the factory 3.42s to 4.11s. That was absolutely essential.

Having said all that, I think most will be perfectly fine with 4.11s and 37s.

Dirty truck???.... I’m with you Mudluvin’.... as often as I am off road and dirty, it makes no sense to try to keep up with keeping it clean. I beat on my trucks and make them work. Scratches and crap on it are just par for the course when it comes to my stuff. Love it

Yeah a lighter fly wheel won't remedy body roll, but my thinking is the lighter fly wheel will support acceleration or regaining momentum after reducing speed or slowing down due to terrain - so with a lighter fly wheel it'll pick up a bit faster than with the stock.
Thinking out loud here...
