Justice Brothers

Justice Brothers traces its roots to a racecar repair and fabrication shop the Justice brothers ran alongside legendary builder Kurtis-Kraft after World War II, later reinvesting racing profits into a lubricants and additives business headquartered in Duarte, California. The company built an early reputation through motorsport ties, including sponsorship connected to a 1950s Indianapolis 500 winning effort and early multi-car NASCAR sponsorship, and now manufactures a line of over 100 lubricants, conditioners, and cleaners sold to automotive, heavy-equipment, agricultural, and industrial markets. JB-80 is the brand's flagship consumer product, an aerosol penetrating lubricant sold in hardware and auto-parts stores nationwide.
