EDEN PRAIRIE, Minn. (Mar. 13, 2026) — Justice Brothers continues its long-standing commitment to grassroots motorsports in 2026, celebrating three decades as a proud sponsor of Speedway Motors IMCA Weekly Racing.
The company, known for its extensive line of automotive performance and maintenance products, traces its roots directly to the racing world. Founded by the Justice Brothers, who began building race cars as teenagers in Paola, Kansas, the company’s history has always been closely tied to the automotive and racing industries.
From those early days in the Midwest, the Justice family eventually moved to Southern California, where they became involved in constructing some of the most legendary vehicles and race cars of the era. Many of those machines are now prized collector pieces worth millions of dollars.
Today, Justice Brothers remains a family-owned and operated company, continuing to manufacture its products in the United States while maintaining its deep connection to racing.
Over the decades, the company has developed an extensive catalog of automotive products, offering hundreds of solutions designed for passenger vehicles, heavy equipment, agricultural applications and commercial trucking. Justice Brothers has also been responsible for several industry innovations, including the world’s first transmission stop-leak in the 1950s, the first non-acid, non-alkaline radiator cleaner in the 1960s and early emission system cleaning technologies introduced in the 1970s.
Justice Brothers products continue to support racers and race teams across the country, and that commitment extends to IMCA’s biggest stage.
During the 2026 Speedway Motors IMCA Super Nationals fueled by Casey’s, Justice Brothers will award a deluxe package of JB car care products to the champion of each Saturday “Big Dance” feature.
The contingency program highlights the company’s continued dedication to grassroots racing and its belief that motorsports remains an important proving ground for automotive technology.
Justice Brothers has supported racing for more than 75 continuous years, a tradition rooted in the company’s origins. In fact, the company itself was founded from the proceeds of the sale of a race car built by the Justice Brothers. That deep connection to motorsports continues today, as the company views racing as both a proving ground for its products and an essential part of its heritage.
