I'm trying to find out if anyone makes a 4.27 R/P for the D30 and D44 for the JK. I seen the 4.27 on a gear chart but wasn't sure if anyone made them for JK's. I have 255/75/R17 with 3.73's and going to 33's. I want to be geared a little lower than what I am now with the new 33's. Any thoughts? This is a DD that pulls a small trailer and sees light to med off road.

 

No. 4.10 is as close as you're gonna get. Then comes 4.88.

 

4.10, 4.56, 4.88, 5.13, (5.38 for rubi's)

 

Yeah. I forgot about the 4.56. They're about useless as tits on a boarhog.

 

So are 3.21s.

 

Please explain as this was the direction I was heading....?

 

I don't know what your particulars are, so it's kinda hard to expound. Tire size? Auto or manual?

 

And do you have any intention of going to a 35" ?

My suggestion:
Manual with 33's - 4.10 or 4.56 for towing
Auto with 33's - 4.56 or 4.88 for towing

If you have even considered the possibility of 35's, bump those up a gear size.

 

Errm, 4.56's are in there too Redneck.

 

4.56's are good for a manual with 33's maybe going to 35's. 4.88's are not much different in ratio and 4.56's will not over rev 33's to much.
