The Yukon mini spool for Suzuki Samurai installs into a standard open carrier in place of spider gears to provide 100% torque to both wheels, delivering full-time lockup. Marketed as a low-cost traction option, it’s intended for off-road or competition applications; Yukon advises against street use where continuous locking can affect drivability.
