I have a 2012 jku with 35's and 3.73's and an auto. i wanted to go to with 4.56's but a sales guy at northridge4x4 said that yukon doesn't make 4.56's and that I woild have to use nitro gears or go 4.88's for yukons. i've never herd of nitro gears. does anyone on here have any experience with these gears,and have any comments? good or bad

 

Was told the same about Yukon, I went with G2's in 4.56's.

 

Personal opinion, haven't driven one regeared. But from what I've heard, I def wouldn't go 4.88 with 35's and 3.6l if you do much highway. 4.10, auto and 35's will give you exactly 2500 rpms at 70

 

1) I don't know if I'd actually call anyone at NR a "salesman". I've spent 11hr days at the shop, wheeled with them in Moab, and harangued them on the phone at great length. Just a bunch of jeep dudes.
2) I've run my '12 auto rubi on stock 4:10 gears at 32",35", and now 37" , and it feels like 4:88 would be pretty low. I'd maybe consider them with my 37's, but def not on 35's.
3) bottom line, I'd trust whatever recommendation NR gives you and roll with it.

 

sooooo, does anyone have any experience with nitro gears? how do they stack up against the yukon gears as for as quality, strength & durability?. i dont want to use an inferior gear just to save some coin. thanks for the reply's so far.

 

i'm guessing by the lack of responses, that nitro gears are not very popular on here!

 

Hey brother, I have 35's and 4.56s in a 2012 auto. I plan on going to 37's and 4.56s keep you in the green on the gear chart with both sizes. I just bought a PR44 from the guys at NR4x4 with the Nitro gears. I agree 100% with NW Apache's recommendation of them, they know their stuff.

I run Nitro Gears and haven't had any problems.

At 75 in a 4.56 I am at 2850 rpm or 2900 hard to see.

I hardly ever run the interstate and us back roads everywhere I go. I like to see the country not the car in front of me.

She purrs right along and the gears are very quite.

Hope this helps.

Got all of it from NorthRidge.
