Manley 26140K Pro Series Valve Spring Titanium Retainer Kit Sport Compact

The Manley 26140K Pro Series Spring and Retainer Kit is a precision-matched valve spring and titanium retainer set engineered specifically for high-revving Sport Compact engine applications. Designed to work seamlessly with today's performance aftermarket camshafts, this kit provides the valve train control needed to extract maximum RPM without sacrificing reliability.

Key Features:

• Chrome Silicon Valve Springs: Manufactured from super-clean, high-tensile-strength chrome silicon steel alloy for exceptional fatigue resistance and long service life
• Classified Heat Treatment: Each spring undergoes precise heat treatment and shot peen processing to maximize load retention and minimize load loss over time
• Aerospace-Grade Titanium Retainers: Machined from certified, heat-treated aerospace-grade titanium bar stock for an optimal strength-to-weight ratio
• Dual-Spindle CNC Machined: Retainers are produced on dual-spindle CNC equipment to exacting tolerances, delivering a superior jewel-like finish
• Precision Tolerances: Retainer lock angles held within 6 minutes (one-tenth of a degree); installed heights held to within .005"
• Reduced Valvetrain Mass: Lightweight titanium retainers allow higher engine speeds while preventing dangerous valve float
• Matched Kit: Springs and retainers are sold as a matched set for hassle-free upgrades

Manley's titanium retainers are an essential upgrade for any high-RPM Sport Compact build. By reducing reciprocating valvetrain mass, they enable the engine to safely reach higher RPM thresholds while maintaining consistent valve control. Combined with Manley's precision-wound chrome silicon valve springs, the 26140K kit delivers a complete, performance-validated solution trusted by engine builders and tuners worldwide.
