Chevrolet Corvette C5 Differential Ring and Pinion - Yukon Gear & Axle - 4.11 Ratio - 97-04. This Yukon high-performance ring and pinion set is made for C5 Corvettes (and compatible C6 applications) where a 4.11 final drive is desired for stronger acceleration and better launch behavior under increased power or larger tires.

Built using Yukon’s advanced design, heat treatment and verification processes, this ring and pinion pair uses high grade steel and a precision gear tooth surface finish to reduce friction and heat under load. Designed to OEM fitment for Getrag transaxles with a 27-spline pinion and main shaft, the set is intended for carriers 3.15 and up. Yukon gear sets are made to handle high torque, offer predictable engagement, and are engineered for quieter operation and easier setup compared with many aftermarket choices. A one-year manufacturer warranty is included and Yukon offers the optional Y.E.S. Plan for extended, lifetime coverage.
