Supertech Performance RET-K24Z7-T1 Titanium Valve Spring Retainer for K24Z7 Engines

The Supertech Performance RET-K24Z7-T1 is a precision-engineered titanium valve spring retainer designed for K24Z7 engines. Manufactured from military-certified 6AL4V titanium alloy and CNC machined to exacting tolerances, this retainer delivers a significant weight reduction over steel retainers — helping to prevent valve float and strengthening valvetrain stability at high RPM.

Titanium retainers are a critical upgrade for performance-built engines, as reduced reciprocating mass allows valvetrain components to respond more quickly and reliably under aggressive cam profiles and elevated engine speeds. The RET-K24Z7-T1 is a direct-fit replacement compatible with Supertech K24Z7 valve spring kits, including the SPR-H1000D-Z7, SPR-H1005D-Z7, and SPR-H100DR-Z7 spring series, and is used in conjunction with KPR-5.5/7A-ST keepers and SEAT-H1020DS spring seats.

Key Features:

• Manufactured from military-certified 6AL4V grade titanium alloy for superior strength-to-weight ratio
• CNC machined for precise dimensional accuracy and long-term durability
• Significantly lighter than steel retainers — reduces valvetrain mass to help prevent valve float
• Compatible with Supertech K24Z7 dual valve spring kits (SPR-H1000D-Z7, SPR-H1005D-Z7, SPR-H100DR-Z7)
• Used with KPR-5.5/7A-ST keepers (7-degree taper) and SEAT-H1020DS spring seats
• Sold individually — order the quantity equal to the number of valves in your engine (typically 16 for a 4-cylinder K24Z7)

Compatibility Note: Verify fitment before ordering if using valve springs other than Supertech-branded units, as retainer geometry is optimized for Supertech spring specifications.
