Product Details

The COMP Cams 4601-1 Hi-Tech Polylock is a precision rocker arm adjuster designed specifically for use with 3/8" stud Ultra Pro Magnum rocker arm systems. This advanced adjustment mechanism provides secure valve lash settings while preventing unwanted movement during high-performance engine operation.

Key Features:

  • Engineered for 3/8" rocker arm studs on Ultra Pro Magnum rocker systems
  • Hi-Tech Polylock design ensures positive locking without backing off
  • Precision-machined threads for accurate valve lash adjustment
  • Durable construction withstands high-RPM valve train loads
  • Maintains consistent valve adjustment under extreme conditions
  • Direct replacement for stock adjustment nuts

The Polylock design combines a lock nut with an internal polymer locking element that grips the stud threads, providing superior holding power compared to traditional jam nut designs. This is essential for maintaining proper valve train geometry and preventing valvetrain damage in performance applications where valve spring pressures and RPM levels exceed factory specifications.
