Finally pulled the trigger on a regear. (37s / 5.38)

It was time to give the gladiator some help with a regear. After mullining over the old 4.88vs5.13vs5.38 thing I landed on Revolution 5.38s for a few a few reasons....

  1. Im in new england and the trips north from the seacoast are riddled with punchy and sustained climbs.

  2. I run with roughly 500lbs of added weight plus multiple passengers regularly. RTT, Rack misc gear etc....

  3. I dont beat the hell out of the rig on the trail. The minor reduction in pinion resilience due to increased surface load concentration is something im not concerned with.

  4. There's plenty of curiosity around this so ill bite the bullet.

  5. And as far as the mfg goes...Revolution seems to have a good reputation so I went with them.

Also tossed in chromo shafts, revolution rear wheel bearings while we were in there and a bunch of armor.

130k miles and all original bearings and ball joints are still good. Even the rear bearings we pulled. Ive been running 37s for 100k. Not too shabby.

Nearing the end of the 500 mile break in and can say this was worth every g spent.

Ill share more after the post break in inspection....

Additional valuable info:

  • Im running a custom Livernois 93 Tune and canned performance transmission tune. Evidently tall gearing throws the stock zf8 into mass confusion as it wants to race to the highest gear for efficiency. My shop said they've never had a rig perform so smoothly after a regear like this and will be recommending this as part of their procedure..
