GSC Beehive Valve Springs and Titanium Retainers Fits Nissan SR20DET S13 S14 Silvia

The all new GSC5051 kit features a redesigned, lightweight Titanium retainer weighing in at only 5grams, vs. the OEM at 18grams! The Nano-Peened round wire Beehive springs will rev well into 9000+ RPMS on 35PSI boost. This kit drops in using your OEM spring locator/seat and valve locks.

The 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.

• Rev faster
• Lighter components
• More durable design
• Less stress on valvetrain components
• Lower spring frequency for more precise valve control
