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.


Toyota Tacoma Gen. 1 (1995 - 2004)

The following gears, lockers and install kits are available for 1995 to 2004 Toyota Tacoma 2wd and 4x4 trucks. All Gen. 1 Tacoma 4x4 models came with the reverse rotation Toyota 7.5" IFS front differential. All Tacomas with a factory rear electric locker came with the Toyota 8" TV6 rear axle and all 4x4 Tacoma trucks without the electric locker were built with the Toyota 8.4" rear axle. 2wd Tacoma trucks came with either the standard Toyota 7.5" rear axle or the larger Toyota 8.4" axle.
