The Yukon Gear & Axle YG GMVET-308 is a high-performance ring and pinion gear set engineered specifically for the GM Cast Iron (CI) Corvette dropout differential in a 3.08 ratio. Whether you're building a street cruiser, a track car, or a weekend warrior, this gear set delivers the durability and precision needed to handle demanding performance applications.

Key Features:

• 3.08 gear ratio optimized for the GM Cast Iron Corvette dropout differential
• 8.20" ring gear diameter for a precise, OEM-spec fit
• 30-spline pinion shaft for maximum torque transfer and strength
• Advanced gear tooth surface finish engineered to reduce friction and heat under high-torque and extended-use conditions
• Manufactured from high-grade steel for both the ring and pinion gears
• Designed using state-of-the-art engineering and advanced heat-treating techniques to meet exacting specifications
• Quiet-running design that is strong and straightforward to set up
• Backed by Yukon's Y.E.S. (Yukon Extended Service) Plan — a lifetime, comprehensive, no-questions-asked protection plan valid for as long as you own the vehicle
