Description

The Yukon YG GMVET-336 is a high-performance ring and pinion gear set engineered for GM cast iron Corvette differentials. It offers a 3.36 gear ratio, an 8.20" ring gear diameter, and a 30-spline pinion, making it suitable for optimizing traction performance or accommodating upgrades like increased horsepower or larger tires. This gear set is compatible with 1963-1979 Corvette models. However, a critical technical note specifies that while this set has a 30 spline pinion, the 1963 and 1964 Corvettes originally came with a 17-spine pinion. Therefore, it is essential for owners of 1963-1964 models to verify their specific pinion spline count prior to ordering to ensure compatibility. Yukon Gear and Axle, the manufacturer, is known for setting the benchmark in quality within the automotive gear industry. They offer the Y.E.S. Plan, a comprehensive, lifetime warranty that covers the gear set for any failure, for any reason, as long as you own the vehicle, though certain restrictions apply.
