Product Details

COMP Cams 10 Degree Superlock Steel Retainers are performance valve spring retainers, also called steel spring retainers or Super Lock retainers. They are built to hold up under the higher pressures that large-diameter performance valve springs produce. Each retainer is designed to locate the spring positively when you pair it with COMP Cams valve springs.

Key Features:

  • 4140 chromemoly steel construction: Precision machined from high-grade SAE 4140 chromemoly steel with no lead.
  • Black oxide finish: Helps prevent corrosion and gives the retainers a clean, finished look.
  • Heat-treated for strength: Helps keep warpage low and resists deformation over long service.
  • 10 degree lock angle: Superlock design for use with matching 10 degree valve locks.
  • Modern top profile: COMP Cams used 3D CAD with FEA to develop a contoured top profile. The design aims for lower stress, increased lift capability and reduced mass.
  • CNC machined: Machined to exact tolerances with CAD/CAM software for consistent fit and quality.
  • Fits all valve stem sizes: Use the retainer size that matches your valve spring outside diameter.

These steel retainers give high-pressure valve springs strength and stability in street performance, racing and engine-build applications. Choose the variant that matches your valve spring outside diameter.
