High links are a great upgrade and recommended for the recreational trail rider or Rock crawler. These proprietary boxed high links are built out of the same Custom Alloy as all HCR kits which is 30% stronger in tensile and yield strength than 4130 series Chromoly. Internal structuring is added for increased strength and fully hand-TIG welded for aesthetics. All needed hardware is included using delrin bushings and crush sleeves. For aggressive desert terrain, duneing, jumping and racing, straight links are recommended for bottoming and side load impact.
