Tomei TA304A-SB01A Valve Springs for Subaru
If you're looking to enhance the performance of your Subaru, the Tomei TA304A-SB01A valve springs are an essential upgrade for enthusiasts aiming for higher RPMs and improved engine reliability. These springs are meticulously engineered to ensure that the camshaft's movements are accurately transmitted to the valves, particularly in high-performance applications where precision is critical.
Why Choose Tomei Valve Springs?
Tomei is synonymous with quality in the performance automotive world, and these valve springs are no exception. Constructed from oil-tempered chromium-silicone alloy steel wire, they are designed to withstand the rigors of high RPM operation. This material is recognized as the best in the industry for performance springs, ensuring that you get durability and reliability when you need it most.
One standout feature of the TA304A-SB01A springs is their nitrogen surface treatment, which enhances surface compression repulsion. This innovative treatment increases the fatigue limit by 1.5 times, significantly reducing the risk of spring failure under extreme conditions. Whether you're running high lift camshafts or pushing your engine to 10,000 RPM, these springs are built to handle it.
