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. 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. This means you can end up stuck with one wheel spinning in the air even with 4WD and two tires on the ground. A locker keeps both axles spinning at the same speed no matter the resistance against tire rotation. Lockers are more popular for off-road focused Jeeps 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.
