37's On My Wrangler 392 *No Lift/Stock Wheels

[SSWIM]

I will get mine on our alignment rack later this week and check it out again. All I know is it drives better than my 20 2.0 JL did.

I wonder what a KO3 would look like? Personally I think a KM3 mixed with a KO2 would be a perfect tire. Basically a siped KM3 and I'd be sold.

Longer sway bar links. Longer shocks. Control arms are longer. So basically it is a lift. I don’t know who told him that. We had a 21 2.0 right next to my 392 and did the measurements. Maybe mine is different. Lol

Bump stops too?

Any idea of the shock lengths?

Thanks for the continuation of your videos.

I finally got around to uploading my video showing off how the Nitto Ridge Grappler 37's fit on the Wrangler 392 stock wheels with no lift. They look amazing, ride great and didn't really hurt the acceleration of the 392, but I do have some rubbing on the lower control arms at full turn, and it does rub the rear inner fender liners when I flexed it out. Let me know if you all have any questions.

Beauty rings! I love it! Frickin jeep claiming they real bead locks lol I love when people think the manufacturer puts the finest things on the cars out of factory lol after market is always better when you own a jeep! Lol

Thank you for sharing that tip at tire discount, that would have pissed me off having to take those off at their shop lol

Just in case Jeep does look at this forum, Willys stock 392,(frame upgrade, etc. stock wheels, etc.).
They can call it the WS, or WSS (Willys Sleeper or Willys Super Stock)

Yes, control arms and sway bar end-links are shorter than from the “Mopar lift kit”. Took measurements myself. I do think the 392 wanders a bit on the highway, even before my 1.5” Teraflex spacer lift.

Highway driving did tighten up to better than stock after switching out my sway bar end links for the longer Mopar. I’d definitely change those out even if your running your 392 at stock height. Maybe $120 total in parts? Not a bad install.

Metalcloak 3.5 Dual Rate kit vs 3.5 GC going on as soon as the bugs have been worked out and available. Have already spoken to Scott. Scott said they threw on the diesel kit to test. Turns out the 392 is heavier enough than the diesel that the kits sags to much in the front. Will need a 392 specific kit.

On 37 I’ve noticed acceleration decreased a little but at highway speeds still pics up like a beast. I’m guessing that’s not unexpected from the higher rev range of a naturally aspirated engine with 470hp.

Agree, a siped KM3 would be the bee’s knees.

Can you measure the bump stops?

Did you get to put on Mopar LCA's? Since they are longer they should improve the ride.

I’ve got a set of mopar lift lower control arms with around 1K miles on them. If anyone is interested in them DM me an offer.

I’m running the Terraflex extended bump stops. Not sure how long they are. They still be replaced with the MC lift.

Ordered them and then canceled the order once I decided to go with a full lift kit from MC.

Has anyone run a 37x12.5 on their stock 392 with a +1 offset wheel? Trying to avoid a -12 if possible, but want to make sure everything fits for most conditions (unlikely to max out the suspension rock crawling but will do a lot of dunes).

This should help
