Comp Cams Conical Valvespring,.660/.932
Revolutionary Advancement In High Performance Spring Technology
Expected to become the new standard in high performance street and race valve spring design, COMP Cams® Conical Valve Springs utilize round wire and feature a diameter and progressive pitch driven natural frequency. This design increases the valve train RPM limit while reducing resonance concerns and decreasing dynamic spring oscillations. The result is longer spring life and the ability to run more aggressive camshafts. A breakthrough in valve spring development, COMP Cams® is the very first to introduce this advanced conical design.
Conical Valve Springs:
- Reduced mass improves RPM stability
- Conical design offers the best natural frequency damping
- Dampens w/o wear, heat/friction or risk from interference contact
- Progressive frequency increases RPM limit & allows for more aggressive cams
- Superfinish surface processing increases both max lift capability & valve spring longevity
- Constantly decreasing diameter from bottom to top reduces active mass & decreases applied forces; Result is longer valve train component life & less parasitic horsepower loss.
- Reduced oscillation in Conical Springs translates to less applied force and stress to the springs. This increases the lifespan of the spring and the valve train. It also allows the use of more aggressive camshaft profiles.

Are OEM products more expensive than aftermarket alternatives?
OEM products might have a higher upfront cost compared to aftermarket parts, but their superior quality and durability often make them a more cost-effective choice over time. Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.
Can I purchase OEM parts online or do I need to visit a dealership?
You don’t need to visit a dealership to get OEM parts. You can conveniently purchase genuine OEM components from authorized distributors and reputable online retailers like Turbo Tech Performance. Our online store provides a wide selection of high-quality parts delivered straight to your door.
Are parts from brands like Mopar, ACDelco, and Motorcraft interchangeable between different vehicle brands?
No, parts from Mopar, ACDelco, and Motorcraft are typically designed for specific vehicle brands. It’s crucial to ensure compatibility with your vehicle’s make and model by checking part numbers and consulting with a knowledgeable expert.
Can I install OEM parts myself, or is it better to have a professional handle it?
While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.
Do OEM parts come with a warranty?
Yes, many OEM auto parts come with a manufacturer’s warranty that covers defects or issues. Be sure to check the warranty details for each part at the time of purchase, and keep your receipt for any potential warranty claims.
