The Yukon Gear Steel Spool for GM 12 Bolt trucks with 30 spline axles is a high-performance locking device designed to enhance traction and power transfer. Constructed as a mini spool, it installs into a standard open carrier and provides full-time lockup, ensuring both tires receive 100% of the engine's torque at all times. This product offers a cost-effective solution for enthusiasts seeking improved traction, especially in high-horsepower applications or vehicles with large tires. Its durable steel construction ensures long-lasting performance and reliable operation under demanding conditions, making it an ideal upgrade for serious off-road or racing setups.
This spool is specifically designed for GM 12 Bolt trucks with 30 spline axles and is suitable for vehicles with gear ratios of 3.73 or higher. It is intended for use in vehicles that require full-time lockup, such as off-road trucks or drag racing vehicles, and is not recommended for street-driven applications due to its locking nature. Installation involves replacing the standard open carrier with this spool, providing a straightforward upgrade for compatible vehicles. The product is ideal for use in off-road, racing, or high-performance scenarios where maximum traction and power delivery are essential.
