Rocker Arm Shaft

DNJ Rocker Arm Shaft

DNJ® Engine Rocker Arm Shafts are vital components in overhead valve (OHV) engines, serving as the mounting base and pivot axis for the rocker arms. These shafts are responsible for maintaining the proper alignment and function of the rocker arms, enabling consistent actuation of the engine’s valves.

Each DNJ® Rocker Arm Shaft is engineered for precise fitment and compatibility with specific engine applications. Depending on the engine design, these shafts may be offered individually or as part of a rocker arm assembly kit.

DNJ® Engine Rocker Arm Shafts are manufactured to meet or exceed OEM quality standards.

DNJ® Engine Rocker Arm Shafts are manufactured from hardened alloy steel to withstand the constant rotational and impact forces exerted by the valvetrain. This material is selected for its superior tensile strength, wear resistance, and ability to maintain structural integrity under high temperatures and frictional loads. Precision machining and heat-treatment processes are applied to ensure proper oil flow, minimal deflection, and extended service life.

DNJ® also offers related components including rocker arms, exhaust and intake valves, lifters, and complete gasket sets, and more. With precision engineering and top-tier materials, DNJ® Engine Rocker Arm Shafts deliver exceptional performance and long-lasting durability.
