GSC P-D Nissan RB26DETT Shimless Conical Valve Spring & Ti Retainer Kit ( Max Boost PSI 50)

If you're building a high-performance Nissan RB26DETT engine and pushing the limits with boost, you need valve springs that can keep up. This kit from GSC Power Division is designed to handle the demands of boosted applications, specifically up to 50 PSI of maximum boost pressure. It replaces your stock valve springs and retainers with a more robust setup that ensures proper valve control at higher RPMs and under significant boost.

This kit features shimless conical valve springs, which offer a unique design that can improve valve train stability and reduce the potential for spring bind compared to traditional dual springs. The included titanium retainers are significantly lighter than stock steel retainers, reducing the overall mass in the valvetrain. Less reciprocating mass means the engine can rev more freely and reliably, especially important when you're making serious power. GSC Power Division is known for its focus on valvetrain components, and this kit reflects that expertise with well-built parts designed for performance.

When installing this kit, pay close attention to the manufacturer's specifications for spring installed height and seat pressure, as these are critical for optimal performance and engine longevity. Because this is a shimless design, it simplifies installation compared to some other setups. Ensure you have the correct tools for valvetrain work, as this is an advanced engine build component. This kit is a solid choice for anyone serious about building a powerful and reliable RB26DETT.
