Locker Recommendations Toyota Tacoma trucks are extremely capable off-road, especially when equipped with front and rear differential lockers. Some models came stock with an OEM rear e-locker but for those that did not, and for the open front IFS differential, ARB offers aftermarket air lockers that will handle all the punishment you can throw at them.
