Introducing our high-performance race valves, meticulously engineered for the discerning automotive enthusiast.

The journey of our race valves begins with a premium one-piece forging process. The valve head undergoes a slow, two-step forging technique that optimizes material flow, ensuring superior strength and durability.

Precision is paramount; hence, each valve is machined using advanced CNC technology through multiple stages. This meticulous approach guarantees that the final dimensions meet the highest standards of accuracy.

To enhance performance, we implement a specialized thermal treatment for relaxation, followed by a nitride curing or coating process tailored to specific applications. This step is crucial for improving wear resistance and overall longevity.

Our commitment to excellence continues with an additional grinding phase, culminating in a patented surface finish. This ensures that every valve is devoid of imperfections, providing precise dimensions that enhance performance.

We prioritize durability in every valve design, focusing on increased resistance to fatigue and superior tensile strength. Each valve tip is hardened to exceed 52 HRc, setting a benchmark for performance in the industry.

When comparing our Supertech valves to competitors, you will find it challenging to discover valves with stricter dimensional tolerances. This precision, combined with our ready valve seats that adhere to equally stringent standards, results in unparalleled sealing capabilities, enhanced performance, and effortless installation.

Our innovative Superfinish coating, when paired with black nitrogen treatment, significantly reduces surface roughness to one-third of that found on traditional chromed valves. This advancement translates to smoother operation and improved efficiency.

The end result is a product that delivers unmatched performance and durability, making it the ideal choice for serious tuners and racers.

At RaceStage.eu, we are dedicated to providing high-quality performance auto parts that elevate your driving experience. Upgrade your Subaru with our race valves and feel the difference on the road or track!
