This Yukon adapter sleeve lets GM 10.5" and 11.5" 14-bolt truck yokes accept a triple-lip pinion seal, converting those yokes to use the upgraded seal style. Built by Yukon Gear & Axle, the sleeve is a targeted replacement component for GM 14-bolt differentials where a triple-lip pinion seal is desired, simplifying seal upgrades without replacing the yoke assembly.
