Supertech Performance RET-TS5.5-T1EX Titanium Valve Spring Retainers

The Supertech Performance RET-TS5.5-T1EX Titanium Valve Spring Retainers are precision-engineered components designed for high-performance and racing engine applications. Machined from military-grade titanium alloy, these retainers deliver exceptional strength-to-weight ratio compared to traditional steel retainers, reducing valvetrain reciprocating mass for improved engine response and higher RPM capability.

Key Features:

• Manufactured from military-certified Grade 5 titanium alloy (Ti-6Al-4V) for superior strength and durability
• CNC machined to tight tolerances for precise, consistent fit with compatible valve springs and valve stems
• Significantly lighter than OEM steel retainers, reducing valvetrain mass and allowing higher engine speeds
• Excellent resistance to heat, corrosion, and fatigue under sustained high-RPM conditions
• Designed for use with Supertech Performance valve springs and compatible 5.5mm stem diameter valves
• Sold individually (per retainer) — order the exact quantity required for your application

Supertech Performance RET-TS5.5-T1EX retainers are an ideal upgrade for naturally aspirated, turbocharged, and forced-induction builds where valvetrain reliability and reduced rotating mass are critical. Always confirm your engine's valve stem diameter, lock groove style, and spring seat dimensions before ordering.
