My gut instinct would be to swap out that tailgate reinforcement for an aftermarket one that replaces the hinges, but the rest of the xr upgrades would be nice to have. Wish that option was available for me when I purchased my jeep!
So far so good on factory mopar gate. No shakes or rattles with 37” MT on beadlocks and a tailgate table
Wouldn't call 4.56 and 37s perfect but better than 4.10 and 37s. I ran 5.13 and 37s on my '19 JLUR and that was much closer to perfect. Based on my experience running 37s with 4.10s, 4.56 and 5.13s, the 4.56 is good enough to save money and not do a gear change. If I did though, this time I'd probably go with 4.88.37" BFGs work great on the Extreme Recon package. They sit at 35.5" mounted, the stock 315/70/17s measured just over 34". Had to move the mounts up on the tailgate bracket. The 4.56 gears are perfect for these tires.
I ran a daystar 3/4 spacer in the rear with bfg 37 zero problems at full flex.
I think the issue with going above 4.88 gears is those teeth start getting really weak in the Dana 44 housing for running bigger tires. At least in an automatic vs manual, i would much rather stick with 4.56 or maybe 4.88 and sacrifice a little gusto in return for reliability on the trails with 37s.
Did you use a tazer to recalibrate or?37" BFGs work great on the Extreme Recon package. They sit at 35.5" mounted, the stock 315/70/17s measured just over 34". Had to move the mounts up on the tailgate bracket. The 4.56 gears are perfect for these tires.
Thanks for that feedback! I was planning on 3/4" Daystar front and rear, but you bring up a good point i may want to prepare for that winch and do the 1.5" up front also.
No, I haven’t and probably won’t. It doesn’t feel any different then the 315’s that came on it. The speedo is a little off, but not as bad as when I had 35’s on my old Gladiator sport with 3.73. It has no problem finding 8th gear and holding it.
Really??? I ran 35 inch good year MT/Rs on a Dana 30 and 35 with 4.88s for a decade and broke nothing... if you are scared of 37s on Dana 44s then you must be pretty new to off roading...I have 37's on my JLR with a Mopar lift and the 2.5+ inches is just barely enough and required slight mods to the inner fender liners. As far as axle gearing with an automatic trans. ,street 4.10 is marginal, off-road it works. FYI, IMHO I will not dump money(gears, shafts,whatever) into an axle housing that has been well shown to be problematic in handling 37" and bigger tires. The Recon axles are said to be stronger than the Rubicon 44's. If the front axle still has the FAD housing and plastic in the Ball Joints, it's still not strong enough. Time will tell about the rear axles strength if the tubes are thicker. I concider my stock Rubicon D44's to be ticking time bombs and wheel as gently as possiblewhen a spotter says bump it or send it. I ask for a tug or pull my winch cable. By far better than breaking on the trail.
Then you should know 37s aren't going to break a d44 unless you go full retard. Afterall full retard breaks everything
i think the point is gearing too high on a D44 being a compromise on strength, not the axle shaft or housing.
I wouldn’t be so sure….
I took a 30mph hit to the front wheel of my D30 on my Jk With big 35s that didn’t bend the Diff but it took out my control arm brackets.
