Gearing question?
 

Hi, I have 99 xj with a 5.5 IRO lift and I plan on running 33's. This is my DD and I know I should regear. I have a d30 and c8.25. I heard 4.56 but I'm not sure.

Ps I drive alot!!

I would think that for a DD 4:10 would be enough. is it an auto or stick? 4.0 or 2.5?

And where could I find cheap gears?

4.0 auto

Do you plan on going bigger tires in the future? If so your only gonna want to regard once, so go with 4.56. Otherwise 4.10s are perfect for 33"s!

Dont cheep out on gears man. And yeah if your sticking with 33"s it "should" be fine. unless you wana spin them on pavement...then go with 4:56 :p

I'm running 33's with 4:56's and it feels perfect.

I went with USA standards & people say they are made by Yukon just not bench spun of xxx amount of miles... that's what makes them "loud", but I can't here them over the tires! Lol no complaints, just remember the d30 will need the 3.73 carrier to install 4.10-4.56 gears

I also have the US standard gear set in my rear axle... no problems from mine. but I have a poly trans mount for compete for noises with.

In my opinion and others will disagree... But if you are going to spend the money to re-gear why make as little of a change as you can to get buy, its not cheaper, or less work... just less gearing lol. I would go 4.56's. I have 4.56's and 33's. feels great. 4.10's just don't seam worth all the work to me...

sounds like ill be going with 4.56s then. What else will I need? The 4.56 for the d30 and c8.25, also the 3.73 carrier in the d30. anything else?

also what companies?

Randys ring & pinion. Your gonna need the master rebuild kits for both axles, but if you've never installed gears before your gonna want to have a shop install them!
