The Pro Krawler Joint is an exceptional tool manufactured with great tolerances for ultimate consistency. The chromoly joint housings are heat treated for enhanced strength and then zinc plated to make them resistant to corrosion. The hard chrome-plated inner ball is constructed from billet 52100 steel for assured strength and durability. The inner raceway offers wear and tear resistance, high frequency vibration isolation, and durability. The joint's body and clevis mounting design feature, which offers +/-20 degree of misalignment is vital as it allows a total of 40 degrees misalignment per side.
