Manley 26130 Pro Series Valve Spring and Titanium Retainer Kit

The Manley 26130 Pro Series Spring and Retainer Kit is a matched valve train component set designed for high-revving sport compact engines. This kit includes Manley spring #22130 and titanium retainer #23130, providing a complete solution for upgrading your valve train system.

Performance Valve Springs:

Manley Performance valve springs are engineered to withstand the demands of aggressive aftermarket camshafts and high-RPM operation. Manufactured from super clean chrome silicon high tensile strength steel alloy, these springs undergo classified heat treatment and shot peen processing to maximize fatigue life and minimize load loss over time. The precision design ensures proper valve train control even under extreme conditions.

Aerospace-Grade Titanium Retainers:

The included titanium retainers are CNC-machined from certified, heat-treated aerospace-grade titanium bar stock using dual spindle machines for exceptional precision. Retainer angles are held to within 6 arc minutes (one-tenth of a degree), and installed heights are maintained to within 0.005 inches. The result is a jewel-like finish with exacting tolerances that ensure consistent performance.

Key Benefits:

• Reduced reciprocating mass allows higher engine speeds without valve float
• Chrome silicon steel construction for superior strength and durability
• Precision-matched spring and retainer combination
• Heat-treated and shot-peened for extended service life
• Ideal for sport compact engines with performance camshafts

Titanium retainers are essential for high-RPM applications where lighter valve train mass translates directly to increased rev capability and improved reliability at sustained high engine speeds.
