Description

Improved Towing. Changing the axle ratio can be done for many reasons. In the case of 2007-2018 Sierras, it is typically to gain better towing or off-road capability. The Yukon Gear 3.90 ratio ring and pinion set is a mid-tier ratio slotted between 3.73 and 4.11. It is a mild upgrade over 3.73s that will return strong grunt down low to help get a heavy load moving with minimal sacrifice to fuel economy or daily driving. 3.90's will also provide a little more bite when off-road and will comfortably handle a tire between 29"-33".

Noise Free Operation. Yukon Gear builds their ring and pinion sets from premium 8620 triple alloy steel, an extremely high strength, durable steel that is significantly more durable than stock. Precision machined and using helical cut teeth provide, Yukon Gears provide smooth enagement and noise free operation.

Professional Installation Recommended. Due to the complexity involved with installing a new pinion and ring gear, it is recommended that the job be done by a drivetrain specialist.

Application. This Yukon Gear 3.90 Ring and Pinion Gear Set is specifically designed for all 2007-2018 GMC Sierras equipped with an 8.5" or 8.6" rear differential.
