What part number should I have installed on the Dana 44 rear in my X? I just looked through my paperwork from my 4.88 Yukon regear and locker install and it looks like they installed a RD117 for gearing 3.73 and down. I have had a few issues with the regear installation including a seal on my drivers rear wheel and am now looking through everything in detail to see if I have any other issues.

 

I was just looking into this for my TJ's soon to be JK axles. The JK rear axle uses the same locker no matter what RP ratio you use. The gears are different thickness instead of using a different carrier. You can look it up on ARB's website. There is a section on the JK axles specifically

 

RD117 is the correct locker

 

That was what I saw on their website as well, but resellers are listing two part numbers based on the gear ratio. I assume you are right, I am just paranoid after the issues I have encountered with the re-gear.

 

Awesome, thanks.
