The RCV 30 Spline Dana 44 300M Locking Hub Gear Upgrade delivers the best of both worlds—the convenience of lockouts with the strength of a slug. Designed as the premium upgrade for Warn Premium Locking Hub Kits, this gear replaces the OEM Dana 44 hub gear with a fully machined 300M alloy steel unit for unmatched torsional strength and durability.

Perfect for high-horsepower setups, large tires, and aggressive trail or competition use. Installation is simple and the upgrade is fully compatible with RCV outer axles.

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 dramatically—bringing 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.
