Product Details

The COMP Cams 10 Degree Superlock Steel Valve Spring Retainer line gives your valvetrain a strong, precisely made steel valve spring retainer for use with larger-diameter, higher-pressure valve springs. Springs with higher pressures need retainers built to handle the load. These retainers are made for that job in performance street, street/strip and racing engines.

Key Features:

  • Chromoly steel construction: Machined from 4140 chromoly steel for strength and stability under high spring pressure.
  • Black oxide finish: Adds a durable, corrosion-resistant coating.
  • 10 degree lock angle: The Superlock design works with 10 degree valve locks and gives positive retention and location.
  • Modern design: COMP Cams used 3D CAD and FEA to develop a contoured top profile. The goal is lower stress, more lift capability and less mass.
  • CNC machined: Machined to tight tolerances using CAD/CAM software for consistent quality.

These retainers suit anyone upgrading valve springs or building a performance engine. COMP Cams offers the line in several spring diameter ranges, so you can match the retainer to your valve spring setup.
