4.11 Ratio Ring and Pinion Gear Set

The Yukon high-performance ring and pinion gear set, model YG GM12T-411, is specifically designed for GM 12-bolt truck differentials. This set offers a 4.11 gear ratio, which is a popular choice for balancing acceleration and cruising capabilities. The specifications include an 8.875-inch ring gear diameter, a 30-spline pinion, and 12 ring gear bolts, ensuring compatibility with the intended GM 12-bolt axle. Engineered by Yukon Gear and Axle, this set is built for high-performance applications. The precise 4.11 ratio is ideal for vehicles that have been modified with larger tires or for those seeking improved off-the-line acceleration without significantly compromising highway drivability. When installing this ring and pinion gear set, it is crucial to follow manufacturer guidelines for proper setup and break-in procedures to ensure longevity and optimal performance. Professional installation is often recommended for differentials to guarantee correct gear mesh, backlash, and preloads. This ensures the gears operate smoothly and quietly, minimizing wear and preventing premature failure.
