GSC Power-Division High Pressure Conical Valve Spring Kit with Ti Retainer for the Nissan VR30DDT includes 24 titanium retainers, 24 conical valve springs, and 24 valve spring seats. 

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 valve spring allowing the users to push higher RPMs, use more aggressive cam profiles, and turn up higher boost pressures.

• Max RPM:  10,500 RPM
• Max boost: 55 psi

GSC Power-Division is glad to reveal the newest addition to our camshaft line, the GSC7043 forged billet S1 set for the VR30 powered Infiniti/Nissan. This isn’t just another cam - lots of research and development went into every aspect of these bump sticks. The billet cores for these cams are proprietary and made in house at GSC. We developed stronger, lighter cams with additional fatigue and wear resistance. CNC machining and grinding gives us the most accurate and repeatable camshafts possible, with precision gun drilling down the center of the cam for oil delivery and weight reduction. This far exceeds OEM durability with the performance GSC Power-Division is world famous for.

Required for the 7043S1 cams are the GSC5083 Conical valve springs and lightweight titanium retainers. These will keep the valve train happy up to 9000 RPM at 40psi of boost. GSC specifically designed the valve springs and retainers for the high horsepower VR30DDTT.

• Intake: Valve Clearance = 0.30mm±0.025mm
• Exhaust: Valve Clearance = 0.33mm±0.025mm

GSC Power-Division Conical Valve Spring Kit with Titanium Retainer for the Nissan VR38DET comes complete with 24 titanium retainers, 24 conical valve springs, and 24 valve spring seats. Conical valve springs, although not a new concept, have proven themselves in the industry, offering several key advantages over traditional spring designs.

One of the primary benefits of conical springs compared to cylindrical or beehive springs is their superior ability to dampen and eliminate valvetrain harmonics. Among these designs, conical springs stand out as frontrunners in ensuring valvetrain harmonic stability. By incorporating varying coil diameters and spacing, conical springs naturally act as harmonic dampers, effectively reducing valvetrain shock. This results in decreased stress, minimized wear, and prolonged lifespan of the included components, a crucial level of protection for modern engines pushed to their physical and mechanical limits by aftermarket modifications.

Each GSC conical spring undergoes a meticulous process, featuring a super-finished surface treatment in addition to a patented, multi-step heat treatment. The result is an exceptionally reliable, high-performance spring that enables users to push higher RPMs, utilize more aggressive cam profiles, and increase boost pressures with confidence.

• Max RPM:  11,000 RPM
• Max boost: 70+ psi
• 2000+ HP

GSC Power-Division Nissan SR20DET Beehive Spring kit with Titanium retainers includes 16 titanium retainers and 16 beehive valve springs. Our beehive spring is made with an ovate wire which utilizes advanced material heat treatment methods for superior load loss capabilities. These springs have the highest level of spring load retention while still maintaining good fatigue throughout the life of the spring. Beehive springs allow for the use of a smaller, lighter retainer allowing for higher RPM and more valve control.
