Type-A Valve Spring Kit for RB26DETT

The Tomei 173004 is a Type-A valve spring kit engineered to meet the demands of high-performance and tuned engines. Reinforced valve springs are crucial for ensuring that valves accurately follow the camshaft profile and maintain proper contact with valve seats during high engine speeds and loads. Constructed with materials like Titanium for valve spring retainers to reduce mass and prevent abnormal valve movement, and utilizing Valve Guides made from Phosphor Bronze Alloy for improved wear resistance and heat dissipation, this kit enhances valvetrain durability. The Type-A springs are designed to support camshaft lifts of up to approximately 10.85mm. This specific valve spring kit is designed for compatibility with the Nissan RB26DETT engine, commonly found in BNR32, BCNR33, and BNR34 chassis.
