Yukon Gear Steel Spool For GM 12 Bolt Truck w/ 30 Spline Axles / 3.73+

If you're looking to maximize traction for off-road adventures or heavy-duty work, a spool for your GM 12-bolt truck differential is a serious consideration. This Yukon Gear & Axle steel spool is designed to replace your open differential carrier, forcing 100% of the engine's power to both rear wheels simultaneously. This means you get consistent grip, whether you're navigating tough trails, pulling heavy loads, or tackling challenging terrain. It's built for vehicles with 30-spline axles and requires a gear ratio of 3.73 or numerically lower.

Yukon performance spools are constructed from high-quality steel, ensuring they can handle the demands of performance applications. By installing this spool, you're opting for a full-time locked differential setup. This unit fits a wide range of GM 12-bolt truck applications, including models like the Chevrolet K10 Suburban and GMC C1500 Pickup from various years. It's important to note that this type of full-time locked differential is not recommended for street-driven vehicles due to the way it affects tire wear and handling during turns.

When considering a spool, remember that it's a permanent modification to your differential carrier. This Yukon spool is designed to work with specific axle and gear configurations, so double-check your vehicle's setup to ensure compatibility. For those who need maximum power to the ground in off-road or specialized applications, this spool offers a robust solution.
