Promaxx Tool is still the industry leader in automotive applications and accessories, aiming to perform the most efficient repairs with the highest accuracy. For exhaust manifold repairs, ProMAXX® tools use precision threaded bushings while competitors use inferior and cheaper plates, clamps, or slip-fit configurations. ProMAXX® tools are designed to provide a quick return on investment the first or second use. Promaxx Tool believes that the small amount of additional money spent on the highest quality and most accurate repairs far exceeds the time and cost required for technicians to replace cylinder heads. For the most accurate results, ProMAXX®EMR tools are bolted to the top or bottom of the head instead of both. This design provides excellent accuracy and alignment to achieve perfect verticality and center point machining.
