Hey Guys,
i have a 2009 JK 3.8 manual trans with 35'' tires, it looses power driving up hill. even downshifting fells like it takes a while to catchup.
any advise?
Thanks
How do i find out the axle set up?What is your axle gear setup? Anything below 4.10 for a manual 3.8 on 35's is going to be sluggish.
It already had the tires when i got it. how do i recalibrate the speedo?Did you recalibrate your speedometer when installing the bigger tires?it

Be careful, those are not always accurate. My build sheet said I had 3.73 gears, turned out to be 3.21 gears.
