Yukon Gear Lightweight Steel Spool For Ford 9in w/ 31 Spline Axles

If you're building a dedicated off-road rig or a drag car, a spool is a smart way to get 100% lockup for maximum traction. This Yukon Gear lightweight steel spool is designed to replace your differential carrier assembly in Ford 9-inch rears with 31-spline axles. It ensures both wheels receive power at all times, which is crucial for serious traction in specialized applications.

Yukon makes these spools from strong 8620 steel and then heat-treats them for added durability. The lightweight design helps reduce rotational mass, which can be a benefit in performance builds. While it offers unmatched traction, keep in mind that a spool is not recommended for street-driven vehicles because it can cause tire scrub and make turning difficult in normal driving conditions.

This spool fits a wide range of classic Ford vehicles, including models like the Ford Bronco, F-100, and Mustang from various years. It's a solid option for anyone looking to maximize grip for competition or extreme off-roading.
