Supertech Performance RET-H1003-T1 Titanium Valve Spring Retainer

The Supertech Performance RET-H1003-T1 is a high-performance titanium valve spring retainer designed for demanding motorsport and high-RPM engine builds. Each retainer is precision CNC machined from aerospace-grade 6AL4V titanium alloy — the same military-certified material standard used in aerospace applications — delivering an exceptional strength-to-weight ratio compared to conventional steel retainers.

Titanium retainers play a critical role in valvetrain stability. By significantly reducing reciprocating mass, they help prevent valve float at high RPM and reduce stress on valve springs, contributing to improved engine response and long-term valvetrain durability.

Key Features:

• Manufactured from military-certified 6AL4V titanium alloy
• CNC machined for precise tolerances and consistent fit
• Reduces reciprocating valvetrain mass versus steel retainers
• Helps prevent valve float under high-RPM conditions
• Designed for use with Supertech spring part number SPR-H1003S and compatible applications
• Compatible with 7° valve locks

Sold individually — one (1) retainer per unit. Order the quantity equal to the number of valves in your engine (e.g., order 16 for a 16-valve engine). Refer to your engine's valve count or Supertech spring kit specifications to determine the correct quantity needed.
