Protect Your Cylinder Head with PAC Racing Spring Seats

The PAC Racing Springs S133 Chromoly Spring Seat is a vital component for any high-performance engine build. Designed to act as a locator and a protective barrier between the valve spring and the cylinder head, this seat prevents the spring from digging into the aluminum or cast iron surface, ensuring the longevity of your investment.

Technical Specifications and Benefits

  • Chromoly Construction: Made from high-strength chromoly steel for maximum durability and resistance to deformation under high spring pressures.
  • Precise Dimensions: Features a 1.650" OD, 0.570" ID, and a 0.630" spring ID to ensure a perfect, snug fit.
  • Low Profile: At only 0.030" thick, this locator provides essential protection without significantly altering your installed height.
  • Improved Stability: Keeps the valve spring perfectly centered, reducing the risk of spring walk and potential valvetrain failure.

Properly locating your valve springs is a fundamental step in building a reliable engine. The S133 locator ensures that your springs remain centered and stable throughout the entire lift cycle, which is crucial for preventing valvetrain harmonics and premature wear. Whether you are building a street-strip engine or a dedicated race car, these chromoly seats offer the peace of mind that comes with using top-tier components.
