Key Features:

These titanium retainers incorporate advanced materials and design to deliver superior performance and durability:

• Manufactured from high-grade titanium for exceptional strength-to-weight ratio
• 7-degree Pro CNC machining ensures precise fitment and consistent quality
• Single spring configuration optimized for the 2AZ-FE engine valve springs
• Lightweight design reduces valvetrain mass, promoting quicker valve response
• Improves valve spring control at higher RPMs, supporting engine reliability
• Corrosion-resistant finish for long-lasting durability under demanding conditions
• Set of 16 retainers included to cover all valves in the engine

Construction & Design:

The retainers are CNC machined from premium titanium, a material known for its excellent strength and light weight compared to traditional steel retainers. This construction reduces the reciprocating mass in the valvetrain, which can help minimize valve float and improve engine efficiency at elevated RPMs. The 7-degree angle design is tailored to fit the specific spring geometry of the 2AZ-FE engine, ensuring optimal spring seating and consistent valve operation.

Ferrea’s precision CNC process guarantees tight tolerances and a perfect fit, which is critical for maintaining valve train stability and preventing premature wear. The titanium material also offers superior resistance to heat and corrosion, making these retainers suitable for both street and performance applications.

Installation & Fitment:

This set of titanium retainers is designed as a direct fit replacement for the factory valve spring retainers on the 2005–2010 Scion tC with the 2AZ-FE engine. Installation requires standard valvetrain disassembly and reassembly procedures. No modifications, cutting, or special tuning are necessary to install these retainers.

• Direct bolt-on replacement for OEM valve spring retainers
• Compatible with single valve spring setups on the 2AZ-FE engine
• No cutting, drilling, or special tuning required
