Yukon steel spool for Dana 60 with 40-spline axles converts the axle to full-time lockup, providing 100% traction to both wheels for off-road and drag racing applications. The spool installs in the carrier like a direct replacement and is made from heat-treated 8620 steel for added strength. This solution is intended for dedicated competition use, not regular street driving.
