High-Strength Titanium Dual Spring Retainers

When every fraction of a second counts, the weight of your valvetrain matters. The PAC Racing 500 Series 1.475-inch Titanium Retainers are engineered to provide maximum strength while significantly reducing reciprocating mass. Designed for dual valve spring setups, these 10-degree retainers ensure superior valve control, preventing float and maintaining consistent spring pressure even under extreme racing conditions.

Technical Specifications

  • Material: High-Strength Titanium
  • Style: 10-Degree Lock Angle
  • Application: 1.475 in Dual Valve Springs
  • OD Steps: 1.140 in / 0.815 in
  • Quantity: Set of 16

These retainers are essential for high-lift, high-RPM engine builds where standard steel retainers would fail or cause valve train instability. The 10-degree angle provides a secure lock, ensuring that your valves stay in place during the most aggressive engine operation. By upgrading to titanium, you reduce the load on your valve springs, which can extend the life of your entire valvetrain assembly. PAC Racing is synonymous with quality in the racing world, and these retainers are a testament to their commitment to performance engineering. Each set is manufactured to precise tolerances to ensure a perfect fit for your specific cylinder head setup. Don't let heavy valvetrain components hold your engine back from its true potential.
