GSC Power-Division Conical Valve Spring with Ti Retainer for RB26DETT includes 24 titanium retainers, 24 conical valve springs, and 24 chromoly valve spring seats. High RPM and High Boost levels are not a problem on these kits. True conical valve springs are not a new concept and are industry proven to provide several key advantages over traditional spring designs. A major advantage of conical springs vs. traditional cylindrical or beehive springs is the damping and removal of valvetrain harmonics. Of the three designs, conical springs are the front runners in valvetrain harmonic stability. Utilizing a varying coil diameter as well as coil spacing, a conical spring acts as a natural harmonic damper in the transfer of valvetrain shock. This translates to less stress, less wear, and a longer life of the included components. This level of protection is needed in today’s engines being pushed to their physical and mechanical limits by aftermarket modifications. Every GSC conical spring offers a super finished surface treatment to go along with the patented, multi-step heat treatment process. The finished product is an extremely reliable, high-performance spring allowing the users to push higher RPMs, use more aggressive cam profiles, and turn up higher boost pressures. GSC Power Division Conical Spring RB26DETT

GSC Power-Division stainless steel +1mm head diameter intake valve with an extended tip length for the Nissan RB26DETT

When creating our valves we set out to create the best performance, longest lasting valves available to the aftermarket. Using advanced 3D design and simulation software, we have created a stronger and higher flowing valve head design. We flow test prototype valve heads in the specific applications to make sure we have the highest flowing valve head available on the market. With the materials used, we have less valve distortion at the face than any of the tested designs. Less distortion allows for better sealing under extreme conditions and more consistent performance throughout the life of the valve.
 

Valve Features:

• Valve Tip Length: Extended tip length for reduced base circle camshafts or for use with OEM 1ZZ Toyota shimless buckets.
  
• Swirl Polished Heads: Engineered for smoother airflow, optimizing the valve's aerodynamics.
• Back Cut Design: Strategically reduces valve weight, enabling higher RPMs.
• Micro-Polished Valve Stems: Minimizes oil retention on the stem, reducing drag for a smoother motion within the guide.
• Premium Material: Intake valves are crafted from modified 21-4n stainless steel for exceptional strength and performance.
• Balanced Keeper Groove: Precisely adjusted to balance intake and exhaust spring pressures, minimizing the need for valve spring shims. This optimization maximizes performance from our spring and retainer kits.
• Compatibility: Our valves seamlessly work with OEM keeper/lock systems. While not mandatory, we advise against reusing any valve lock on performance applications due to potential material grooving.
• Quality: Backed by GSC Power-Division's commitment to quality and performance.
