Tech Insight

The factory Dana 44 hub gear is a known weak point when subjected to modern off-road power levels, oversized tires, and aggressive terrain. By swapping to a 300M hub gear, torsional capacity increases dramaticallybringing your locking hub strength closer to that of a full-time slug while keeping the drivability and flexibility of a lockout. This is a highly recommended upgrade when running RCV Dana 44 outers to prevent hub-related failures on the trail.
