Hey guys i got a 99' xj i just did a 6.5 RC long arm lift kit with 35 inch MT baja mtz tires with a sye and i was trying to find out what gear set up should i go with its my daily driver and i do highway driveing with it so need some advice on what gear set up should i go with and if i should change the diff or not and with this set up does anyone know what teeth gear should i need for the spedo gear?? Thanx guys!

 

Good lord, punctuate FFS

This subject has been covered to death. You need to search to find the answers you're looking for. But I know you won't do that. So, get 4.88's if you have an auto transmission. 4.56 for manual transmission. Speedo gear can be found by crossreferencing your tire size and gear ratio with one of the many charts on google.

Not trying to be harsh. But you need to learn how to do some of your own legwork. That aside hope it helped.

 

Thanx bud kinda new to this so next time i'll search a little harder but thanx for the help!!!!

 

He is correct 4.88's for the AW4 and 35" tires 4.56 manual, both of those equal stock gear in the XJ for that tire size. BTW now is the right time to install lockers front and rear same labor to do both at same time.

 

Yeahh thank alot, I was thinking about doing that aswell since im in there, now should i change the whole axle or are the stock once good? Any particular lockers I should use?

 

Your 99 should have the D30 and Chy 8.25 with 29 spline axles which are good. I used Detroit Lockers in mine but an ARB air locker might be a better choice for the D30 on a DD. Mine isn't a DD but drive it a lot on the roads year around and they don't bother me at all.

 

Ok kool ill look into them, now should i go with the air lockers on the front and rear or just the front? Thank alot btw!

 

Detroit out back, E-Locker up front.

4.88's FTW!

 

I agree, selectable up front and a locker in the rear, u could do a selectable in rear if u got the money.

As everyone say, 4.88's for 35's

 

X2, I went Yukon up front & ARB in the rear. I'd reccomend dele tables F/R if your wallet can afford it. My wife drives mine at times & selectable a have perfect road manners. Also check out OX, that was me second option.

Good luck.

 

Yeahh just checked all that out and i dont think ima spend all that money on them i dont do that much off roading to be spending that lol might just go with a simple rear locker! Thank alot guys!
