The front Dana 44 axle receives strengthened axle tubes with heavy-duty end forgings and heavy-duty cast front and rear differential covers. The unique rock rails are specially designed to accommodate 35-inch tires, a popular upgrade among JK enthusiasts. As with other Rubicons, the Recon features Jeep’s Rock-Trac transfer case with a 4:1 low-range. In addition to the axle and drivetrain upgrades, the Recon has a 1/2-inch lift, and 32-inch BFGoodrich KM tires, available body-color fender flares, a dual-vent Power Dome hood, and 17-inch low-gloss Granite Crystal painted alloy wheels.

35s ok now? 4.10 gears? Really? I'm confused..

Are you suggesting that 35" inch tires combined with 4.10 gears and a 4:1 low range ratio is not sufficient? I would think that the combined 4.1 gears and 4:1 low range is a very potent combination for 35" tires and would even allow 37" tires to be passable for many who live in the flat lands.

I run 37's on my 4.10's with manual and it's just fine. Before that I ran 35's for 4 years. what are you getting at?

Its saying the rock rails are cut to fit a 35" tire.

I also run 37's and 4.10's, on road its fine.

No guys I'm not making any suggestions, I've just been preached to for so long about the Bruhahaha 35s and how jeep will abandon you. Equally, If some guy buys a 50k dollar JKURec and slaps on 35s and struggles up the Grapevine in SoCal or Donner, and suddenly feels a huge loss of performance, would the advertising start to feel a tad misleading?

I just slapped 35 (315/75r16) MTRs on my JKUR (2015& 4.10) and it drove fine, but I haven't recal the trans yet with superchip and have concerns (not regret, just concerns) about family trips and steep grades/trans temps/motor temps, etc

Sorry not in a club or anything and nobody locally has a lot of input. Just confused about the whole thing.. >:)

how tall is your lift? when you hit around 3" and above your driveshaft angles are something to worry about. also know that at some point in the future you may have premature wear of other things like ball joints, steering components, etc. I take it you have an auto?

with the whole recon thing, it's just Jeep trying to squeeze every bit out of the JK before production ends. I see what you're saying though, it gives off the impression that you can throw on 35's and be done with it. and a lot of people probably will.

I did the teraflex leveling kit (2 front, 1 rear)+
Flatties. So thankfully I didn't throw too much out of whack. Yeah I'm an auto. 4.10
We will see what this super chip f5 trans calibration thing does..

That article was written in 2011, which means that in terms of engine power it's no longer valid.

With the 3.6 (2012 and newer), 37s with 4.10s and an auto trans is very doable. I ran that way for a few months before upgrading to 5.13's, which was always the ultimate plan. If you're not going to load up heavily, or tow a lot, you might run that way for a long time, and it couldn't help but be better with 35's.

The rest of what the article said borders on hysteria. They are right about the increased wear, of course, but you're also going to increase wear just by taking it off road. I've run 37's on unmodified Dana 44's for 45,000 miles and the only damage I've done was a bent rear flange from Fordyce Creek. No gussets, no truss, no damage. In spite of all the doom and gloom in that article.

I did have to go through the front end at about 35,000 miles because virtually every moving component was worn out. I replaced the ball joints, tie rod, drag link, and track bar, as well as adding the synergy track bar and steering sector shaft brace. I have a 4.5" AEV left, so all of those components were stock until I replaced them. I replaced the Bilstein shocks less than 5000 miles ago, so they had about 40,000 on them, but I don't consider that to be excessive. And again, that's with 37's, so with 35's you shouldn't have as much problem but you'll have to do it eventually.

You'll probably have some decreased performance on steep grades like Donner, Tehachapi, or the grapevine. But really, how often do you drive those grades? My point is that it's really probably not a major consideration in your overall plan. If you go up to Shaver, I would want a trans temp gauge because that grade is brutal even on a stock rig.

reminded my four door '11s first set of tires and wheels were 325/75r16s and man I loved those. Aired down , that little extra bit of tire between wheel and earth afforded by the 16s made great traction.
Just not enough tire selection over 34-35"available for 16" wheels!
yeah, FCA is just milking the test for the last JK/JKU configs they can before the upcoming new model release, as @lost_jeep stated.

I get it, and that was my take. Ok, is Jeep accepting that a good amount of Jeep owners want leveling kits and up to 4" lifts, with 32s and up to 35" tires as soon as they can muster the funds?

I've seen hit and miss with dealerships accepting or rejecting off-road mods.

Kinda what I mean..
