"Toyota 8.4" Tacoma ARB Air Locker assembled differential. 100% ready to drop in featuring the world famous and super reliable ARB. The ARB is a selectable locking differential with a "open" and "locked" position. When using the "open" function the differential operates as a normal stock differential, allowing slippage and reducing tire ware. After the ARB is "locked" in the differential now becomes a full locker and both tires on the axle will turn the same speed. This gives you the ability to have a street friendly differential and a full 100% traction off-road locker. "
this 3rd was installed on July 2010 and will be removed shortly from truck. approx mileage is about 8,000-12,000 miles.
i am switching my carrier to another style since my recent accident when i was hit on my passenger side. i will stand by this 3rd 100% and once it is removed from the vehicle i will have it thoroughly inspected upon shipping or selling
