$386.39
GSC Power-Division Beehive springs feature some of the most impressive manufacturing techniques in the industry. Its beehive spring uses an ovate wire, which utilizes advanced material heat treatment methods for superior load loss capabilities. What this means is their spring has the highest level of spring load retention while still maintaining good fatigue through out the life of the spring. Only the best materials go into the GSC Power-Division Beehive valve spring. Each batch is scrutinized for tensile strength properties, ductility, inclusion content, and fatigue toughness.
Some have inquired as to the benefits of a beehive spring vs. the dual springs that are sold by others. While some might find that the beehive spring design is new, it has been used commonly in many OE engines as well as in all of the NASCAR and F1 engines of today. Why? The beehive shape is more stable than standard single or dual cylindrical springs. The beehive design, which incorporates an ovate wire, is more than capable of the performance demands that were previously only matched by a Dual Springs. With the smaller and lighter retainer used on the beehive valve spring allow for higher RPM and more valve control. So beehive valve springs, with their lighter weight retainers allow for engines to rev quicker and maintain a more stable valve motion than the traditional cylindrical springs.
Beehive Spring Benefits:
- Rev faster
- Lighter components

- Less stress on valvetrain components
- Lower spring frequency for more precise valve control
- More valve control equals more aggressive cam profiles
