Up for sale is an OEM rear axle differential assembly - no miles on it! 3.36 Ratio - if you are not sure, dealer can tell you by VIN # or we can help you ID No damage to the mounts etc! Fits: 2007-2015 Armada (2.94 or 3.36 ratios used so please verify - contact us if not sure first please!); 2007-2010 QX56 (only came 3.36 ratio in QX56) The item is new as shown. From handling, light oil and dirt marks from handling common to guys handling in warehouse but no damage except mentioned. Please contact us with any questions!! Thank you!!! PLEASE NOTE! Due to outrageous shipping costs in today's economy, oversize boxes are nearly double what is used to cost to ship...for that reason, States in the Mountain and Pacific time zones are sadly costing buyers more for shipments. We do apologize for this but the truth is, it costs more just to ship out West...which we can not justify making folks in the rest of the USA pay for with "free shipping" as a part of the total cost just to cover the Western States costs. Thank you for understanding! This is over 120 pounds...you will have to sign for it.
