Product Details
This Yukon Gear & Axle spool is a direct replacement for your Ford 9-inch differential carrier assembly, giving you 100% lockup. It's built from 8620 steel and heat-treated for added strength, making it a solid choice for vehicles focused on off-road performance or drag racing. Because it locks both rear wheels together, it's not recommended for street-driven vehicles where it can cause tire scrub and increased wear.
This spool fits a wide range of classic Ford vehicles, including models like the Ford Bronco (1966-1986), Ford F-150 (1975-1987), and Ford Mustang (1965-1973). Installation is straightforward as it bolts in place of your existing differential carrier. If you're building a dedicated performance rig, this spool offers a cost-effective way to achieve full traction.
