Anyone regeared yet? Have 37’s on mine and would like to regear but local experienced shop was unsure of parts needed. Had 4.56 on my previous JL and thinking of 4.88’s on 392

Check your tranny ratios. 4.56 should be perfect with 37's... just one humble opinion...Anyone regeared yet? Have 37’s on mine and would like to regear but local experienced shop was unsure of parts needed. Had 4.56 on my previous JL and thinking of 4.88’s on 392
Been driving with the 37’s for a few weeks and just on initial impressions I would be happier with a regear. I regeared my 6 cylinder 2015 JK (35’s) and 6 cylinder 2019 JL (37’s and 4.56) (both auto) and was happier after regearing. Just waiting on the upgrade shop (Brandons auto and truck in Pompano, Florida - they merged with Florida Fortec) They did a fantastic job on the 392 wheels, tires, bumpers, winch etcThey claim with the engine no need to regear, but I had an 03 wrangler I regeared to 4.56 with 33s on it and could go up to a 35 maybe a 37 inch tire with a 4.56...idk I definitely want to regear at some point as they most likely went with smaller gears for speed and on road performance
Yeah I think I wanna do a metal cloak 3.5 inch lift kit, 37" tires, and 4.88 regear at some point then!Been driving with the 37’s for a few weeks and just on initial impressions I would be happier with a regear.

Look at the similar post “Gearing”, there is a reply in that thread that is very helpful and informing me to avoid regearing on the 392.Yeah I think I wanna do a metal cloak 3.5 inch lift kit, 37" tires, and 4.88 regear at some point then!
Yeah, sometimes people forget (or don't realize) that lowering the gearing within the same axle housing comes at the cost of ring and pinion strength.My $0.02 ... personally, I’m leery of regearing too low in this thing without going to a Dana 60 or even 70. The amount of torque generated off idle is huge. Multiple that out thru 1st gear low, even with the 2.72 t-case and 3.73s and you’ve got serious axle breaking potential if you’re wheeling it, particularly in high traction situations where tires may get bound up.
I probably will regear with 37s, but with so much torque, I’m contemplating no more than 4.10s since I have no plans for a 60/70, though I do plan on RCVs.
looking forward to seeing the direction people go, though -
Your point is exactly what I’ve been saying off this forum. The whole reason mopar went 3.73 gears instead of the standard rubicon 4.10 is so the axles don’t implode under the torque generated by the 6.4, same with the diesel. I won’t regear until I upgrade axle assemblies.My $0.02 ... personally, I’m leery of regearing too low in this thing without going to a Dana 60 or even 70.

Do you happen to have the part number(s) you used for the re-gear??I regeared to Spicer 4:56 a few weeks ago. I put 37x13.5x20NittoMT the day I bought it so I haven’t really known what it’s like to drive it stock. I ordered these before the Recon was even announced. Over 500 miles the gas mileage is about the same. It never down shifts to 7th out of 8th for overpasses and head winds like it did before. Definitely feels quicker especially in the midrange gears. I’ve done several Brake Tourque Launches before the regear and one today after the regear…..I chirped those big ass 37s today, that never happened before the regear. I feel the my Jeep universe is right now. I used the Tazer to recal, speedO is dead on at all speeds.
They are the Dana44 advantek by Spicer:Do you happen to have the part number(s) you used for the re-gear??
Just the gears. Same axlesThe Recon version has 4.56 gears and 35" tires... did they change anything else (axles, etc) or just the gears??
