WHY UPGRADE?
Upgrading to titanium retainers offers significant performance advantages over steel options. Titanium retainers are much lighter, which increases efficiency and allows the engine to rev higher without losing control of the valvetrain. Our precision-machined titanium retainers are designed to evenly distribute the spring load across their entire surface, reducing the risk of failure at higher RPMs. Additionally, less weight on top of the valves contributes to more precise and stable valvetrain movement, ensuring optimal engine performance.
PRECISELY ENGINEERED WITH PREMIUM MATERIALS
Each IAG Single Valve Spring and Titanium Retainer Set includes 16 valve springs made from high-quality chrome silicone alloy steel. Designed to withstand extreme shock loads and stress, our springs excel in high-RPM applications. Also included are 16 strong and lightweight titanium retainers that are precision-machined for optimal performance. Their reduced weight enhances efficiency and enables the engine to achieve higher RPMs. Best of all, our titanium retainers are machined and manufactured right here in our facility in the USA.
FITMENT AND OPERATION GUIDELINES
The IAG Single Valve Spring and Titanium Retainer Set is used on the IAG 550 and 750 Cylinder Head packages found in our 550 and 750 EJ25 longs blocks which are rated up to 750BHP. The spring set may be used for stock replacement or with Stage 1 and Stage 2 camshafts utilized in mild street and road race applications. Please note that for safe operation, this spring set should not exceed 8000RPM.
