True conical valve springs aren’t a new concept—they’ve been proven in the industry to offer several key advantages over traditional spring designs. One of the biggest benefits of conical springs compared to traditional cylindrical or beehive springs is their ability to dampen and eliminate valvetrain harmonics. Out of the three designs, conical springs lead the way in maintaining valvetrain harmonic stability.
Thanks to their varying coil diameter and spacing, conical springs act as natural harmonic dampers, absorbing the shock in the valvetrain. This means less stress, less wear, and a longer life for your engine components. This level of protection is essential for today’s engines, which are being pushed to their physical and mechanical limits.
Every GSC conical spring undergoes a super-finished surface treatment in addition to a patented, multi-step heat treatment process. The result? A super reliable, high-performance spring that lets you push higher RPMs and use more aggressive cam profiles with confidence.
If you’re looking to get the most out of your engine, GSC conical springs are the way to go. They’re built to perform, engineered to last, and designed to let you take your engine to the next level.
