• Titanium valve spring retainer set, 1.80/.870 dimensions, 16 pieces
• Matched specifically to 22185-16 springs
• Significantly lighter than factory steel retainers
• Reduces valvetrain mass for higher safe RPM

A Larger Retainer for a Larger Spring

This Manley titanium retainer set is dimensioned at 1.80/.870 specifically to work with Manley's larger 22185-16 valve springs, a different pairing than the smaller 1.050/.755 retainer and its 22180-16 spring. Titanium construction makes these retainers significantly lighter than the factory steel pieces they replace, and that reduced reciprocating mass directly helps the larger spring control valve movement at higher RPM. Less valvetrain mass means a higher safe RPM ceiling before valve float becomes a real risk. It's the kind of upgrade that quietly does its job without ever needing a second thought.

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 22185-16 spring part number. That's real, functional engineering, not just a marketing claim.
