GSC Power-Division Beehive springs feature some of the most impressive manufacturing techniques in the industry. Our beehive spring uses an ovate wire which utilizes advanced material heat treatment methods for superior load loss capabilities. What this means to you is our spring has the highest level of spring load retention while still maintaining good fatigue throughout 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.
The beehive valve spring shape has become the buzz lately. Some have enquired 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 there lighter weight retainers allow for engine's to rev quicker and maintain a more stable valve motion than the traditional cylindrical springs of yesteryear.
- Rev faster
- Lighter components
- More durable design
- Less stress on valvetrain components
- Lower spring frequency for more precise valve control.
- More valve control equals more aggressive cam profiles
- All of these items help to return more power for you to enjoy!

I paired these springs with the Kelford 214B cams. Installed with head on the car. Been running for about 2k miles now. Install was a little tricky. Had to make my own tool to compress the springs. The beehive are quite a bit stiffer than stock. MAP provided excellent service as always.
Great product, neatly packaged and unharmed. I did gain about 9hp just by installing them, and about 30-40tq. MAP is great at getting your order on time and by set date but down side is that the cams were delayed, but that’s ok when you’re not in a rush to build your car right. So this time the wait WAS WORTH it. MAP is always the way to go!!!
A++ .. Installed easy quick.. Quality of the product was amazing
Great when upgrading your OEM cams.
I just want to start off by saying the customer service was awesome! I ordered the GSC valve springs/retainers to go along with my GSC S2 cams that I got through MAP. I also figured the 2 would pair together good since the cams and valve springs/retainers are both GSC and I wanted to stick with GSC instead of another brand of valve springs/retainers. Always low prices!
