Yukon Gear Mini Spool For GM 12 Bolt Car & Truck w/ 30 Spline Axles

Yukon Gear & Axle is known for making solid drivetrain components, and this mini spool is a great example for anyone looking to get serious traction out of their GM 12-bolt differential. This part is designed to install into a standard open carrier case, turning it into a full-time locker. What that means for you is 100 percent of the engine's power is always sent to both rear wheels, no matter what. This setup is ideal for off-road use, drag racing, or any situation where maximum grip is the priority.

Built from high-quality materials, Yukon performance spools are made to handle the demands of performance applications. While it offers the full-time lockup of a more expensive full spool, the mini spool is a more economical choice. It's important to note that this type of full-time locker is not recommended for street-driven vehicles due to tire wear and handling characteristics on pavement. For vehicles with large tires or high horsepower, a full spool might be recommended, but for many performance builds, this mini spool provides a strong, cost-effective way to achieve full-time traction.

This mini spool fits a wide range of GM 12-bolt applications, including many Chevrolet Bel Air, Impala, and C10 Pickup models from the 1960s and 70s, as well as various Buick Wildcats and GMC C15 trucks. If you're building a vehicle for serious off-road or track use and need consistent power to both rear wheels, this Yukon mini spool is a well-built option.
