Manley 23205-32 Titanium Valve Spring Retainer Set — 32-Piece for 22205 Springs

Machined from aerospace-grade, heat-treated 6AL-4V titanium to exacting CNC tolerances, these retainers deliver a dramatic reduction in valvetrain mass compared to steel alternatives — translating to quicker rev response, tighter valve control, and more stable valvetrain behavior at elevated RPM. Designed specifically to pair with the Manley 22205 valve spring, each retainer features a 5.50 mm stem diameter, a 6-degree valve lock angle, a first step diameter of 0.920 in, and a second step diameter of 0.690 in, with a step height of 0.080 in.

Key Features:

• Heat-treated aerospace-grade 6AL-4V titanium construction
• CNC machined to exacting tolerances for consistent, precise fitment
• Significantly lighter than steel retainers — reduces valvetrain mass for faster rev-up
• Helps maintain spring pressure at high RPM, minimizing valve float
• 6-degree valve lock angle; 5.50 mm valve stem diameter
• First step diameter: 0.920 in | Second step diameter: 0.690 in | Step height: 0.080 in
• Designed to pair with Manley 22205 valve springs
• Quantity: 32 retainers per set
• Sport Compact series — purpose-built for race and aggressive street applications

Whether you're building a dedicated race engine or pushing the limits of an aggressive street build, these Manley titanium retainers provide the lightweight durability needed to unlock your engine's full performance potential. Suited for the Toyota 5.7L 3UR-FE engine. Installation should be performed by a qualified engine builder familiar with valvetrain assembly procedures.
