Not wanting 37 for looks, but for clearance, no way can I or will I re gear I am ordering the procal next week, just worried about making the truck a slow turd. I am also a little worried about them balancing, in my small town not many options. Keeping stock rims and most likely will stick with nitto ridge grapplers thats what I have in 35 now. Thanks for all the info.

I would love to regear. Whats holding me back, even more than the cost, is the issues with the factory warranty. That and the fact that it seems dang near impossible to find the right guy/parts for the job.

The OEM power wagon is a slow turd from the factory just like any gas motor 3/4 Ton is. Don’t let that effect your decision. Not only ground clearance but the ride off-road improves substantially on 37s and the distribution of 7400lbs of truck across the larger area is worth its weight in gold. DO IT

THIS, I have heard so many stories of people getting a re-gear and having a shop screw it up, even when it was supposed to be a reputable shop. This is one of those things that has to be done with precision. Makes me nervous too.

Im fairly confident I have a capable shop... but still a bit skeptical because of the stories I have read about. At this point Im most concerned about the warranty. Im thinking I should just cancel the dang lifetime warranty deal.

When Thuren regeared his truck for the 38’s he had a dealership do it and used oem AAM parts. Preserved the warranty that route apparently

Yeah, well it's an investment in not just money, but trust. No one wants to have their trust broken and have spent like 4k :shock: :shock: :shock:

If I can convince Chris to show me how, I might do mine myself. At some point I'm moving to 4.88's here with Dynatrac hubs.

That newer white PW for sale that I trolled your build thread with a while back had that exact setup (hubs, gears and 37s) and the guy claimed his mileage was just as good or better than with the truck in stock configuration. He said he did the gears himself too. I guess if you have the right tools and knowledge than all should be good. But, for whatever reason it sounds like it is a bit more difficult than a “typical” gear swap.

If you have the correct tools and do it by the book, you should be 100% fine. Just like any precision assembly. I think the difference between having a dude that’s been a machinist and knows to be patient and take his time and constantly remeasure and knows that specs are requirements that you need to achieve, versus someone whose worked in a garage and has occasionally used a dial indicator and plays wild on tolerances all the time, is going to be a big difference. There are also preferences and little tricks that come into play.

A common dude with good sense can rebuild an engine perfectly if he follows the instructions and has the parts and tools. It’s the lack of patience or time, going cheap on buying new and correct parts, and not getting the tools you need that I would assume cause issues with gear install and many other things.

He used the gears out of a PW. I would not let the shop he used touch my truck; Don had a good experience with them but I know several people that have not.

I had a major axle shop in SLC do a set of gears for me. The axles seals were leaking within 20 miles and the gears whined. The shop charged me to replace the seals and clean the brakes. Their excuse for charging me is I brought them parts and they were unknown quality (I brought them spicer and dana parts). The gears blew up a few thousand miles later. An aircraft mechanic friend of mine and I redid the gears in his garage and they turned out perfect.

A related question, the ProCal says it does not work with 2018 models. I just ordered my 2018 and 37s will be here before the truck will. Anyone know why it doesn't work? Its the same as a 17 from everything I can tell.

To be clear, I wasn’t suggesting people use the same shop, just exploring an avenue for people to regear and maintain their warranty.

Perhaps you know, does AAM already have deeper gearsets available for the newer trucks or is it only for the older ones?

4.88’s are as low as you can go with AAM gearsets for the new power wagons.

Older, not for the newer. Their website states they had 4.88's but that seems to have disappeared. Not sure what's up with that.

This, I've rebuilt a few engines, put heads back together. There are some things you have to do right and not fudge. Fuck up, and you end up with valves hitting your cylinder heads. Ask me how I know about not using the proper torque spec on the rocker arms on an LT1.

That's the thing that makes me most nervous. I'd love to do gears, but I need someone like Marcus or something with a bit more attention to detail than my ADD to show me.

Luckily I eventually figured out how to put a motor back together properly.

I don't think the manufacturer's warranty would have covered any part of the gear change.

Minor thread hijack. Are you guys just using the Procal to adjust tire sizes? I have the rental devices coming to fix tire size, add fog lights to high beams, and adjust tpms without dealer intervention. I'm just wondering if I'm missing the boat on something with the Procal?

The Procal is worth owning if you plan on changing tires more than one time. Otherwise, The Autel and AE are more than sufficient. I'm about to reset my fog lights to turn off with high beams. The fogs reduce long distance vision at night and it is just one more button to push when I have to dim the highs for oncoming traffic. Also, I would set my TPMS to 20 PSI if I had to do it over again.

Read the detailed thread, because I asked about that and clarification. He has Yukons.

Interesting... i was leaning towards 35 PSI which i consider highway safe and turning on the fog lights with high beams...

I thought he started out with yukons and traded up for AAM’s after.... I do have a shitty memory, though.

Mine are set to 30 PSI. I run 35 front and 30 rear. On really cold mornings before the tires have warmed up I get TPMS warnings because the tire pressure hit 24 PSI in the rear. It doesn't matter how low you set the TPMS, they will pick up pressure drops while your driving. If you have 35 PSI in the tires and the air starts leaking out of a nail hole you will get a warning. If you air down and don't want the warning, set them lower to begin with.

The fog cubes I have are really only good for fog. They do not improve vision when the high beams are on. I have HID's high and low so there is plenty of light.

ProCal is a must. The truck improved a lot with the procal and the shift hunting. But it still feels like I'm towing when I'm not when I go up anything over 2000ft in elevation. We have one pass near us that is only from 3200ft to 7200ft and you feel it.
Since ABQ is at 5000 feet and I live at 6000 maybe not a good idea for me.
