In the world of pins, bushings, and fifth wheels, impact is the enemy. Mammoth trusts the XD5 because that 5% Moly content acts like a physical "plating" on the metal. Even if the grease is hammered out, the Moly stays behind to prevent metal-on-metal destruction.

Phillips 66® Megaplex XD5 is a high-performance, heavy-duty, lithium complex, extreme-pressure grease containing 5% Molybdenum Disulfide (Moly). It is specifically designed for use in construction and mining equipment operating under severe conditions. The 5% Moly content provides an extra margin of protection against galling and wear under heavy or shock loading. It features excellent water resistance, high dropping point, and superior protection against rust and corrosion.
