The Yukon 8620 steel full spool for Chrysler 8.75in housings with 30-spline axles converts a differential to 100% lockup, delivering continuous traction to both wheels. Heat-treated for strength and installed in place of the carrier assembly, it’s a cost-effective choice for dedicated off-road and drag race vehicles. Not recommended for street-driven use.
