Do you need a locker for a Jeep JK?
Unless you have a Rubicon, or you ordered your Wrangler with a LSD or a locker, your JK came standard with open differentials in both the front and back axles. Open differentials transfer torque to the wheel with the least amount of resistance.
Can a locking differential be installed in a JK?
Installing a locking differential in your JK will augment the off-road capabilities of your rig. Combined with other drive line components , a locker can bring you and your JK across more challenging obstacles.
Which is better a locker or a LSD in a Jeep Wrangler?
Lockers are more popular for off-road focused Jeep Wranglers because they’re not as road friendly as a LSD. A LSD is an excellent balance for road faring and trail tackling Wranglers. A LSD prevents too much torque from spinning a tire without traction, but not as aggressively as a locker would.

Why do you need to regear your Jeep Wrangler?
This means that with a 30 inch tire you need to apply 30 times more force to the axle in order to turn the wheel. By regearing to a shorter gear, you will increase the amount of force that is being sent to the axle, this allows your Jeep to move the tires with less of a strain on the engine.
What kind of gear set does a Wrangler have?
Wranglers that are equipped with the Rubicon package typically come with the 4.10 gear set in their Dana 44 axles. The chart below shows the relationship between gear ratios and tire size. The numbers across the top are gear ratios, the numbers down the left side are tire sizes in inches, and the 4 digit numbers in the white boxes show RPM.
