Default Gear ratio for 2010 Jeep Wrangler Sport Jk?
Could someone please tell me what gears a 2010 Jeep Wrangler Sport JK has? I also have a 4" lift with 35 " tires and need to know what, if any, gears do I need?

It left the factory with either standard 3.21 or optional 3.73.

The easiest way is to register at the jeep website and enter your vin. It will tell you what your jeep left the factory with. Then again if you bought the jeep used they could have been swapped by the previous owner.

3.73 or 3.21, doesn't matter much. With 35s + 3.8 powa + automatic; you are likely getting passed by every car on the road.

If you have a tow package from the factory that can also mean you prob have 3.73's.

Manual or auto ? If auto, it left the factory with 3:73s as there were no other options.
