Guys what would it cost to install gears on my 12JKU...I was told to
go to 4.10 gears...I am running 35" tires summer - 32" tires winter...
Any input would be great...Got a price from a retailer here want to see
if they are good or not...

 

I paid 700.00 for labor

 

$1500 parts & labor from a local Drivetrain shop with 30+ years experience. Don't skimp here and do your homework on the shop. This is one of those areas where a little mistake can cost big. Just a thought.....

 

Does 4 hours per axle for install sound right...

 

Good to know...this is a reputable 4 x 4 shop...That's pretty much all they do...
Cool thanks for info here...

 

So basically what i got was...$2000.00 all installed out the door...Need to change gear oil
after 400 - 500 miles also...Sounds about right then...
Thanks for information here guys...
Knowlegde on this is not great...Does 4.10 gears sound about what i need here...

 

What ratio do you currently have? If its 3.21s you might be satisfied with the 4.10s if you only plan on running 35s. If you ever want to go bigger I would think about 4.56 or 4.88s.

 

i have 4.88's with my 37" KM2's and i love it with my 3.6 Pentastar

 

3.21 gears it is...not much trail riding if any...By riding with 3.21 gears will this
screw up anything...Used the Procal not sure if it's accurate...I'm highway driving
at 110 KM - 2000 RPM...Is this about right...Thanks for your help...

 

Pentastar has enough power for sure...S/C is down the line possibly...
