Lockers & Limited Slips

Traction is vital on and off-road. Limited slips will add more "transparent" traction, whereas lockers will provide more "positive" traction. Most limited slips will engage and disengage without you even noticing. Lockers will tend to make more noise, but provide the most traction and strength. If you want the best of both worlds, try a selectable locker like the Yukon Zip Locker, Auburn ECTED or ARB Air Locker. Selectable lockers will allow you to disengage the locker for casual street driving, then flip a switch to engage the locker when you really need traction the most.
