Gearing dilemma

4.88s are great if you have a stick, with the auto you need all the gear you can get. My axles came 5.13 and with 35s they were great. With 37s I'm in 3rd gear all the time on the highway. This would be a similar situation for you with 35s and 4.88s, don't settle till you find a shop that will install the gears with a warranty.

By the way its been my experience that most gear manufacturers don't honor warranties
, they just blame any failure on setup regardless of the facts. So if you get a parts and labour warranty chances are the shop is eating the cost of the second set of gears.


There must have been a time
when we could have said no.

Regardless, they still offer a 2 year warranty on the 5.13. I can't recall a gear set that went broke due to improper manufacture. We had some that were noisy no matter of set up, most likely due to improper lapping from the factory.
 
That’s a good thought. And it hadn’t occurred to me even though I’ve chatted with them a couple of times! I’ll call them again :-).

I don’t know how widely prevalent they are on the east coast. No one I’ve spoken to at a shop had heard of them. Yet...

I know personally that Revolution Gear honors their gear warranties.
I'll drop the name at a couple of shops around here that I know have had issues with that by both g2 and Yukon. May help them out.

Keep in mind what was said earlier... it's rare when the gears themselves are the cause of problems. Installing gears is an art that even experienced installers occasionally get wrong, manufacturing gears is a precise and very (!) repeatable process.
 
I believe there are several sources in addition to Revolution for quality 5.13 gear sets for the non-Rubicon Dana 44. Is that incorrect?

My recollection is that one of the gear installers I spoke with had no issue installing 5.13 gears from one of his regular suppliers, but would not install gears from Revolution because he had no personal experience with their products, already had several well-known product lines that he knew and trusted, and was uncomfortable extending his shop warranty to unknown products. It was simply a business decision on his part to limit his shop warranty to familiar products, not experiment with customer vehicles, and never install customer supplied parts. No hard feelings. Had I not wanted 5.38 gears for my Rubicon Dana 44 axles, which are only available from Revolution, I probably would have purchased another brand from him and had him do my re-gear.

I think OP's goal is to find: (1) a respected gear shop that is familiar with and frequently does re-gears for TJ's; (2) which will provide a warranty for parts and labor and stand behind the brands it carries; and (3) who understands that there is sound reasoning for using 5.13 gears in OP's particular application and won't try to talk him out of it. The brand of the gear set secondary as long as it is one of the major players.

I don't think that is too much for him to ask and he shouldn't settle for less.

Yukon now also imports 5.13 gears for our TJs, they come from Circle K who also makes RGA's gears.

I think Yukon is who my shop typically uses. I’ll make sure I let them know.

Are they identical to RGA’s version?

Thoughts why Yukon would only offer 1yr warranty vs RGA’s 2yr, if they are identical?

Perhaps a brand that they typically use can get them more comfortable. Thanks!

I do not have personal knowledge of this, but there is a very well respected TJ/LJ builder/designer/supplier who maintains that several well known "high end" gear and axle companies obtain their gear sets from multiple sources so one never really knows what will be in the box when it arrives. It might be Circle K one week and someone else's gears the next.

However, it really doesn't matter in your case. You need to find a gear shop who uses brand name gears, who will install 5.13 gears without giving you a hard time, and who will stand behind the products they sell and the labor they perform. As long as it is a recognized brand the particular brand or the actual source of the gears is secondary.[/QUOTE]

Honestly, I know this probably isn’t what you want to hear, but I would take it to another shop even if it meant driving a ways. 5.13 is the way to go, no question about it. You won’t be happy with 4.88 gears on 35” tires.

Absolutely this ^^^. I made the mistake of doing 4.88s in my '06 LJR and on 37s with the Auto. I alos live in the foothills at 2000' Elevation. Not good. Go with the 5.13s. With that OD ratio you will be glad you did.

All the gears from Revolution Gear always come from Circle K. It's other brands like Yukon where it may be Circle K or it may not be depending on the luck of the draw.
