This listing is for a brand new Tundra front IFS open differential with a 4.30 ratio ring and pinion. This factory original diff has less than 100 miles of use and was replaced with a locker for improved off highway traction. The 4.30 ratio will also offer more horsepower and torque than most ratios included from the factory. This differential will fit the front of all Tundra's 2007-2016. It makes a great inexpensive repair part or a reliable spare for the serious off roader. Its worth over $1000 new and is very hard to find in this condition. It was carefully removed and is always properly packaged to ensure safe delivery right to your door! Dont miss out on genuine OEM Toyota quality at this low price. Thanks for looking.
