Manton can create and produce a pushrod or rockerarm adjusting screw stronger, more durable and suitable for your engine needs. All products are made from the best quality materials available. Tubes are made of 4130/4135 seamless chromoly or cold working tool steel and are available in a variety of heat treated conditions. This allows us to manufacture a pushrod to enhance your specific application. Because every engine is different, we do not mass produce. All pushrods are custom made “In House” per order, with an average turnaround of 24-48 hours. We take pride in knowing that we produce the highest quality parts available anywhere in the world.
