First Look at the NEW JL D44 Ring and Pinions!

[Tech Tim]

Thanks Tim,
I have the Manual JLUS w/220mm in the Rear so my reasoning for the 4.10 was trying to keep it towards "Stock" numbers when I went to a 35, but I am surprised to see the difference is only 179 RPM (knowing that it will be different than 179 because of the .72 vs .67) at the end gears.

With the 0.72 6th gear, you'll see a change of about 100 rpms higher over those numbers I posted.

Maybe going with a 4.56 combo and having the extra "umph" would be a better option...

Take that list of RPMs out on your next drive and cruise at those different RPMs. It'll give you a close enough feel what it would feel like with the different RPMs.

Does @Northridge4x4 do installs? It would be a great excuse for a Colorado trip

Yes we do! Give the Denver store a ring (720-213-0114) and ask for Chris, tell him I sent you over from the JL Wrangler Forums.

I’m going 4.88 with my manual JL! Only thing I can do to help that crawl ratio until a rubi case or an atlas.

Plus I frequently go over 6k feet so it helps a lot

Jury still out on 35 or 37 for me. This time around though, if I go 35 i’ll Just stick with Rubi 4.10s. If I do 37s I’ll be going 4.88s. I’ll have the auto in my 19.

Are Dana gears the only ones available? Any word on aftermarket gear availability?
