Manley 26110K Pro Series Valve Spring Titanium Retainer Kit Sport Compact

The Manley 26110K Pro Series Spring and Retainer Kit is a precision-matched set engineered specifically for high-revving Sport Compact engine applications. Combining performance valve springs with aerospace-grade titanium retainers, this kit delivers the valve train control needed to support aggressive aftermarket camshafts and elevated engine speeds.

Key Features:

• Chrome Silicon Valve Springs — Manufactured from super-clean, high-tensile-strength chrome silicon steel alloy for maximum fatigue resistance and long service life
• Classified Heat Treatment & Shot Peen Processing — Each spring undergoes controlled heat treatment and shot peen finishing to ensure ultimate fatigue life and minimize load loss over time
• Aerospace-Grade Titanium Retainers — Machined from certified, heat-treated aerospace titanium bar stock for exceptional strength-to-weight ratio
• Dual-Spindle CNC Machined — Retainers are produced to exacting tolerances on dual-spindle CNC equipment, delivering a superior jewel-like surface finish
• Precision Tolerances — Retainer angles held to within 6 minutes (1/10th of a degree); installed heights held to within .005"
• Reduced Valvetrain Mass — Lightweight titanium retainers allow higher engine speeds while preventing dangerous valve float, without compromising durability
• Matched Kit — Springs and retainers are paired and validated together for consistent, reliable performance

Designed for the demands of today's Sport Compact performance builds, the Manley 26110K Pro Series kit provides the high-RPM valve control required when running aggressive camshaft profiles. The reduced reciprocating mass of the titanium retainers is especially critical in applications pushing the upper limits of engine speed, making this kit a go-to choice for serious Sport Compact engine builders.
