Supertech Performance RET-AU5VE-ST3 Titanium Valve Spring Retainer

The Supertech Performance RET-AU5VE-ST3 is a precision-engineered titanium valve spring retainer designed for high-performance engine builds. This retainer is specifically designed for Audi and Volkswagen 5-valve exhaust applications, delivering the weight reduction and durability needed for aggressive camshaft profiles and high-RPM operation.

Key Features:

• Manufactured from high-quality, military-certified titanium alloy for exceptional strength-to-weight ratio
• CNC machined for precise fitment and tight tolerances
• Significantly reduces valvetrain mass compared to steel retainers, allowing for higher RPM capability
• Compatible with Supertech SPR-H1000 series dual valve springs
• Designed to work with upgraded camshafts and higher lift profiles
• Ensures long-term durability even under extreme racing conditions

Supertech titanium retainers are ideal for track, race, and high-performance street applications where valvetrain stability at elevated engine speeds is critical. The reduced reciprocating mass helps prevent valve float and allows the use of more aggressive valve spring rates. Each retainer is sold individually, so be sure to order the quantity needed for your specific engine configuration.
