This listing is for a Jeep Wrangler TJ & LJ or Grand Cherokee ZJ  Dana 30 front 3.07 ratio ring and pinion set. These factory original parts have very low mileage and were removed in perfect working condition. They were replaced with a lower gear ratio for larger tires being installed. These parts are in great shape. This ratio is very rare and will offer far more gas mileage savings than what comes with most Dana 30 axles from the factory. These gears can make inexpensive repair parts or a great spare set for the real off roader. These OEM parts are worth over $200 new. They have been carefully removed and they will be properly packaged to ensure safe delivery right to your door! Dont miss out on genuine Dana Spicer quality at this low price. Thanks for looking.
