Yukon Full Spools are a cost-effective way to convert a diff to 100% lockup. Installation is easy as they install in place of your differential carrier assembly. Each Yukon spool is made from high-quality 8620 steel and heat treated for additional strength. A spool is an outstanding choice for dedicated off-road and drag racing vehicles only.
Fits Dana 44, 3.92 and up, 30 spline. Yukon spools provide 100% traction to both wheels for off road, racing and performance applications.
