    Excellent Rock Crawling Performance. From the factory, Sierra pickup trucks and come equipped with a gear ranging from 3.08 to 4.11 depending on the transmission and trim package. When towing heavy, running large tires or engaged in hardcore crawling, where lot's of low end torque is needed, the factory gearing options are too high to provide the necessary power and throttle control. A 5.13:1 rear ring and pinion from Yukon Gear is optimal for 2007-2018 GMC Sierra owners with a 35"-40" tire intending to participate in serious wheeling and rock crawling. Daily driving is somewhat affected with such a low gear and can result in a marginal increase in fuel consumption and engine noise. 

    Forged in the Fires of Mordor. There can only be ONE Ring… and pinion to rule them all. And Yukon Gear makes it. Blended from chromium, molbydenum and nickel to form a triple steel alloy, 8620 steel is extremely strong and perfectly suited for the harsh conditions that a driveline component has to endure. The 30-spline pinion and 8.5" ring gear are direct replacements for the factory pieces.

    Professional Installation Required. Properly seating and aligning a rear ring and pinion requires very precise measurements with no room for error. For this reason, it is recommended to have a drivetrain specialist complete the job.

    Application. This Yukon Gear 5.13 Ring and Pinion Gear Set is specifically designed for all 2007-2018 GMC Sierras equipped with an 8.5" or 8.6" rear differential.
