Description

The Yukon high-performance ring and pinion gear set offers a 3.90 ratio, designed to enhance the performance of GM C5 and C6 Corvettes. Engineered by Yukon Gear and Axle, these sets utilize advanced design, heat-treating, and quality control processes to meet exacting standards. This specific gear set is compatible with carriers 3.15 and up and fits Getrag C5 and C6 models equipped with a 27 spline pinion and main shaft. However, it is important to note that this set does not fit 2005+ C6 Z06, ZR1, or Grand Sport models that feature a 30 spline pinion and main shaft. Yukon is recognized as a top choice for automotive professionals and enthusiasts, offering a wide selection of gear ratios to suit various needs, whether for increased horsepower, larger tires, or optimized traction performance.
