Product Description
The Yukon YG GM12T-411 ring and pinion set delivers a 4.11 gear ratio for GM 12-bolt truck differentials, built to Yukon\'s high-performance standard with an optimized tooth surface finish that reduces friction and heat under sustained load. Manufactured from high-grade steel and quality-tested in Yukon\'s in-house labs, it\'s designed to run quiet and hold up under towing, larger tires, or added horsepower.
Since this is a gear set only, it\'s best paired with a matching Yukon installation kit and small parts for a complete rebuild. Fitment is designed to OEM spec, so it drops into the GM 8.875\" 12-bolt case as a direct performance upgrade over factory gearing.
