Rocker Cover

Rocker Covers, found within the Engine Parts > Heads & Valve Train section, seal the valve train components of internal combustion engines in passenger cars and commercial vehicles. These covers prevent oil leakage from the cylinder head while protecting the valve train from debris and contaminants. Typically constructed from materials like aluminum or plastic, rocker covers contribute to engine cleanliness and longevity. Examples in our catalog include covers for MAN trucks (MPN 51.03400-6007, 51.03401-6039), as well as parts for Mercedes-Benz Trucks, Renault, and Volvo Trucks applications. Ensuring a proper seal is critical for maintaining optimal engine performance and preventing oil-related issues. Replacing a damaged or worn rocker cover restores this protection and contributes to overall engine health.
