GSC beehive valve springs and titanium retainers allow for more precise valve control and higher revs. The beehive spring design utilizes an ovate wire with advanced heat treatment for longevity and better stress distribution for reliability at high revs. With its narrowed top diameter it allows for a smaller and lighter spring retainer while at the same time providing a variable frequency which allows for higher rpms when compared to traditional springs. Nano-peened for durability.
Suggested max revs with an S3 cam profile is 9500rpm and max boost of more than 35psi. Coil bind is 14mm of valve lift.
Usually ships in 2 to 3 days.
