VQ35DE VQ35HR High-Lift Valve Spring Set

The Tomei valve springs set is a specialized valvetrain upgrade engineered to maintain accurate valve timing and prevent valve float at high engine speeds, particularly when using aggressive camshaft profiles in high-performance Nissan VQ35DE and VQ35HR engine applications. Utilizing a durable oval wire design, these springs are constructed as a high-lift type capable of supporting up to 11.00 mm of valve lift. Compatibility is specific to JDM vehicles including various Nissan models like the Fairlady Z, Skyline, Elgrand, and Fuga equipped with VQ35DE or VQ35HR engines. As these are performance-oriented components, buyers should verify specific engine and year compatibility prior to purchase, as professional installation is typically required for valvetrain modifications.
