The Tomei TA304A-NS01A valve springs are engineered for high-performance applications, specifically designed for the Nissan VR38DETT engine found in the Nissan GT-R models from 2007 to 2025. These springs are crucial for maintaining precise valve operation at elevated RPMs, making them an essential upgrade for any serious performance build.
Crafted from oil-tempered chromium-silicone alloy steel wire, these valve springs are built to withstand the demands of high-performance engines. This material is recognized in the industry for its superior performance characteristics, offering enhanced durability and resistance to fatigue. The innovative design optimizes spring performance, effectively minimizing valve bounce and ensuring stability even under extreme conditions.
The TA304A-NS01A features a nitrogen surface treatment that enhances the spring's compression repulsion capabilities. This treatment increases the fatigue limit by 1.5 times compared to standard materials, allowing the springs to perform reliably at engine speeds reaching up to 10,000 RPM. This makes them suitable for applications involving high-lift camshafts, where traditional springs may fail.
