ProMaxx is a family owned business that began in 2012 by purchasing, and expanding on, the remnants of Patriot Performance and Alabama Cylinder Head Exchange. Specializing in all types of cylinder heads, from diesel to performance, the ProMAXX performance line has become a passion....with the mission of providing the best performing cylinder heads on the market at a price that cannot be beat. With over 30 years of racing experience at nearly every level from Brackets to Pro Mod and Pro Stock we have learned what works and what does not on the street, as well as the strip. ProMaxx has designed a completely new line of performance heads that meet or exceed established performance levels.
