After completing Elephant Hills in Canyonlands, my husband and I are thinking of upgrading our 2019 JLU Sport for more challenging trails. We plan to upgrade the axles in preparation for 37s in the near future.
Current state: It seems my JLU Sport has Dana M186 (D30) front and Dana M200 (D35) rear. It's a JLU Sport, no lockers, with 3.45 stock gear ratio.
Option 1: Replace the front axle with Dynatrac PR44 with an e-locker. Only regear the rear axle to match the front.
Option 2: Replace the front axle with Dynatrac PR44 with an air locker. Install an air locker in the rear axle. Although our preference is e-locker, it seems there is no e-locker for M200 (D35) rear axle.
Option 3: Replace front and rear axles with JLU Rubicon takeouts.
Let me know you guys opinions on above options.
On gear ratio, considering we are going to run 37s in the near future, it seems 4.10 would be sufficient (37 inches/31.5 inches * 3.45 = 4.05). However the re-gear ratio offered by Rebel Off-road is 4.88 and above. My question is if 4.88 is really necessary. What are the major cons, given we are running on 34 inch tires right now?
Last but not least, I'd like to hear your suggestions on what else to change when upgrading the axle(s)?
Thanks a lot!
