Description
The rocker box serves as a critical seal on your Twin Cam engine—any leakage compromises oil pressure, cooling efficiency, and overall engine reliability. Drag Specialties engineered this unit with precision tolerances and exact dimensions to eliminate guesswork during installation and ensure a true, leakproof seal that holds up to repeated heat cycles and high-RPM operation. Since two are required per motor, investing in quality construction now prevents costly gasket failures and downtime later.
