Tomei Racing Valve Springs, Type-B RB25DET R33 GTS25T TA304A-NS06B

Tomei Racing Valve Springs, B Type With Retainers for the RB25DET R33 GTS25T, offer a high-quality solution for transferring the precise movement of the camshaft to the valves, even at high engine speeds. These springs are designed for high-performance engines where reliability and durability are crucial. Tomei's engineering precision ensures that the materials chosen are of the highest quality, with surface coatings and technologies that maximize performance and lifespan. Every product goes through extensive testing to ensure it meets Tomei’s rigorous standards for durability, quality, and performance.

The springs are made from oil-tempered chromium-silicone alloy steel wire, widely considered the best material for high-performance springs. This material is enhanced through a surface treatment process that permeates nitrogen into the spring, significantly increasing its fatigue limit and ensuring high durability for use with high-lift camshafts. Tomei’s innovative design suppresses valve jump and bounce, even when the engine's RPM limit is pushed higher. This allows for greater performance at extreme engine speeds, exceeding 10,000 RPM, something previously unattainable with other springs.

Tomei also implements a specialized process where small steel balls are shot onto the spring’s surface at high speeds to further increase its fatigue resistance. This method prevents sagging and maintains the spring’s shape over time, even under high stress. The combination of durable materials, advanced design, and rigorous testing ensures that Tomei Racing Valve Springs deliver reliable, long-lasting performance, making them a top choice for those pushing their RB25DET engines to the limit.
