Description

Manley Performance Valve Spring and Retainer Kit 26180 takes the guesswork out of making your valvetrain race-ready. Engineered for maximum durability, stability, and precision in high-performance and racing applications, these chrome-silicon alloy springs provide exceptional fatigue resistance and high-tensile strength, ensuring consistent valve control at extreme RPMs. This kit combines Manley's upgraded 245 lbs./in valve spring set (part 22180-16) with matching heat-treated aerospace-grade titanium retainers (part 23180-16), CNC machined to exacting tolerances.

Designed for Subaru EJ20/EJ25 engines with upgraded camshafts that require valve springs for increased lift and higher RPM use. Maximum net lift 0.525" (stock 0.370"); coil bind 0.845"; rate 245 lbs./in. Kit includes 16 valve springs and 16 titanium retainers; valve locks are NOT included.
