Description

The Zumbrota Drivetrain YG GM8.25-411R is a high-performance Yukon Ring & Pinion set designed for GM 8.25" IFS reverse rotation differentials. This set provides a 4.11 gear ratio, crucial for optimizing performance and drivability. Key specifications include an 8.25" ring gear diameter, a 30-spline pinion, and 10 ring gear bolts. It is designed to fit GM 8.25" IFS vehicles up to the 2013 model year. Important technical notes indicate that 2010 GM 8.25IFS Front ends originally equipped with a factory 3.08 gear will require a new carrier when changing to this ratio. If purchasing gears of 3.42 and up for a factory 3.08 application, you must also purchase a YC G26018131 case. The deck height varies based on the original ratio, with 1.780” for 3.08 ratio and 1.920” for 3.42 and up ratios.
