USA Standard Ring & Pinion Gear Set For GM 12 Bolt Truck in a 3.73 Ratio

If you're working on a GM 12-bolt truck and looking to change your gear ratio, this USA Standard Ring & Pinion Gear Set from Yukon Gear & Axle is a solid option. This set features a 3.73 ratio, which is a popular choice for balancing highway cruising with off-the-line acceleration. It's specifically designed as a 'thick' gear set, which is important for applications that originally came with 3.42 or numerically lower ratios, ensuring proper gear mesh and strength.

Yukon Gear & Axle puts these sets through rigorous in-house quality checks, covering dimensions, materials, and fitment to make sure they meet or exceed original equipment specifications. This attention to detail means you're getting a well-built component that's ready to handle the demands of your drivetrain. This set is compatible with a wide range of GM 12-bolt truck applications, including models like the Chevrolet C10 Pickup and GMC K15 Suburban, spanning many years from the mid-60s through the mid-80s.

When installing a new ring and pinion, it's crucial to follow the manufacturer's break-in procedure to ensure the gears seat properly and achieve their maximum lifespan. This set is a direct replacement for many GM 12-bolt rear ends, making it a straightforward upgrade for your truck.
