Manley 26190 Pro Series Valve Spring Titanium Retainer Kit

The Manley 26190 Pro Series Spring and Retainer Kit is a precision-matched valve train component set engineered for high-revving sport compact engines. This kit includes Manley spring #22190-16 and titanium retainer #23190-16, providing a complete solution for performance engine builds.

Premium Valve Spring Design:

Manley Performance valve springs are manufactured from super-clean chrome silicon high tensile strength steel alloy, specifically formulated to withstand the demanding requirements of aftermarket performance camshafts. Each spring undergoes classified heat treatment and shot peening processes to maximize fatigue life and minimize load loss over time, ensuring reliable valve train control at elevated RPM ranges.

Aerospace-Grade Titanium Retainers:

The included titanium retainers are CNC-machined from certified, heat-treated aerospace-grade titanium bar stock using advanced dual-spindle equipment. This precision manufacturing process maintains retainer angles within 6 arc minutes (one-tenth of a degree) and holds installed heights to within 0.005 inches, delivering a jewel-like finish and exceptional accuracy.

Performance Benefits:

• Reduced reciprocating mass enables higher safe engine speeds
• Prevents valve float in high-RPM applications
• Superior fatigue resistance for long-term reliability
• Precision tolerances ensure optimal valve train geometry
• Matched spring and retainer pairing for consistent performance

This kit is an essential upgrade for sport compact engines operating at elevated RPM levels, where valve train control and reduced mass are critical to both performance and reliability.
