Yukon 67-72 Chevrolet Camaro Re-Gear Kit - 30 Thin Spline 3.73 Ratio

If you're looking to get more out of your classic muscle car's acceleration, this re-gear kit from Yukon Gear & Axle is designed for GM's robust 8.875-inch 12-bolt rear axle. This kit allows you to change your vehicle's gear ratio to a more aggressive 3.73, which can significantly improve your car's launching ability and deliver that "shot out of a cannon" acceleration you're after. It's a popular choice for hot-rodded vehicles and fits a wide range of classic GM applications, including models like the 1967-1972 Chevrolet Camaro, 1964-1973 Chevrolet Chevelle, and 1969-1972 Pontiac Firebird.

This kit includes a well-built ring and pinion gear set with a 3.73 ratio and a 30-spline pinion gear, specifically designed for thin gear applications. Beyond the gears themselves, Yukon includes all the necessary bearings and installation hardware to complete the job. This means you get the 2.25-inch axle bearings (AK 1563) and all the small parts needed to properly set up your differential, ensuring a solid installation. The 8.875-inch ring gear diameter is a hallmark of the GM 12-bolt, known for its strength in performance applications.

Upgrading your gear ratio is a fundamental way to change how your vehicle performs. A lower numerical ratio like 3.73 generally means better acceleration from a stop, while a higher numerical ratio is better for highway cruising. This kit is a comprehensive solution for those looking to optimize their classic vehicle's performance for spirited driving and improved launch characteristics.
