The Tomei Valve Spring Set is engineered to meet the demands of high-performance engines, specifically the RB26DETT Type-A, ensuring the precise transfer of camshaft movement to valves at high RPMs. These springs are crafted from durable SWOCN-V material and feature a nitride processing for superior wear resistance and longevity. Key specifications include a compatible lift of approximately 10.85 mm, an alignment of 3.90, and a free length of 44.0mm. The set length is 37.7mm, lift length is 27.2mm, and compress length is 26.1mm. They are rated with a set load of 24.0±7% kgf and a lift load of 77.2±7% kgf. Benefits of this valve spring set include improved reliability in high RPM operation, enhanced initial response, and high durability against metal fatigue, shocks from jumps and bounces, surging, and sag. These features contribute to consistent performance and a longer lifespan under extreme conditions. This valve spring set is designed for the 1995-1999 Nissan GT-R.
