    Get Up and Go. A Yukon Gear Ring and Pinion set with a 4.11 ratio for 2007-2018 GMC Sierra can be considered the premier ratio for heavy towing or an entry-level ratio for off-road wheeling. This higher ratio gear and pinion will increase engine RPM at any given speed, thereby entering the powerband earlier and making it easier to pull off the line or crawl along a trail. Paired with a tire between 30"-34", Yukon Gear 4.11's are a great choice for trucks that tow heavy and tow often, venture off-road and will still perform admirably putting around town.

    Premium Quality. Yukon Gear manufactures this 4.11 ratio GM 8.5 & GM 8.6 from high strength 8620 heat treated triple alloy steel. Both pieces are precisely machined leaving smooth surfaces without any burrs. Helical cut teeth mesh smoothly and do so without making any noise.

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

    I just bought a 2018 Chevy 1500 5.3L 2wd. i installed a lift kit with 35s. i want to change the ring and pinion gear to a 4.11. The rear end in the truck is a 12 bolt rear end. how can i know that im buying the correct gear? 8.5 - 8.6 or 9.5? 10 bolt vs 12 bolt? pat

    • We recommend consulting with your local Chevy dealer, with the VIN number to determine which rear your truck was equipped with to be completely sure.
