• Matched specifically to 22180-16 springs
• Significantly lighter than factory steel retainers
• Reduces valvetrain mass for higher safe RPM

Lighter Retainers, Matched to a Specific Spring

This Manley titanium retainer set is dimensioned at 1.050/.755 specifically to work with Manley's 22180-16 valve springs, ensuring correct installed height and geometry rather than guessing at compatibility between mismatched parts. Titanium construction makes these retainers significantly lighter than the factory steel pieces they replace, and that reduced reciprocating mass directly helps the valve springs control valve movement at higher RPM. Less valvetrain mass means a higher safe RPM ceiling before valve float becomes a real risk. It's a straightforward improvement that's easy to appreciate once it's installed.

A Full Set of 16 for Consistent Valvetrain Behavior

This set includes all 16 retainers needed for a complete EJ20/EJ25-based engine, keeping installed height and spring pressure consistent across every cylinder. That consistency matters for predictable valvetrain behavior rather than one cylinder behaving differently than the rest. It's the correct retainer choice specifically when paired with Manley's matching 22180-16 spring part number. That combination of durability and performance is what makes it worth the upgrade.
