The Pro Krawler Joint is a revolutionary joint manufactured with the tightest tolerances for ultimate consistency. The Chromoly joint housings are heat treated for increased strength and then zinc plated for corrosion resistance. The hard chrome plated inner ball is machined from billet 52100 steel for strength and durability. The inner raceway provides wear resistance, high frequency vibration isolation and durability. The body and clevis mounting width ratio of the Pro Krawler Joint is a key design feature which provides up to +/-30 degrees of misalignment. that is a total of 60 degrees of misalignment per side.
