Well i jus bought an 08' jeep rubicon jk and i am gettin a 4" superlift with the 37" Toyo open countrys. I was wonderin if i should i get a bigger ration of gears. or what please help thanx

Im new here lol !!! thank yall

 

highly recommend getting new gears for the larger tires. i am not exactly sure what size you will need, my guess would be somewere over the 5.o mark. you may also want to look into getting new driveshafts as well.

 

No less than 5.13's. If you have an automatic you might want to go with the 5.38's that are just now becoming available. 4.88's are not enough except for a 6 speed and 35's.

 

Use the search button.
5.13s will be a must IMO

 

Your definitely gonna need bigger gears, and new drive shafts. I'm guessing you're going long arm. Don't forget the track bar and relocation bracket, and all the control arms. Not trying to be all know it all, I just hate it when I get stuff and then I'm all, "fuck, now I need that too."
