Request return authorization (RMA) within 30 days of delivery for eligible items. Keep items unused and uninstalled, with original packaging and accessories. Electronics, liquids, special orders and other categories are excluded.
Email sales@frsport.com with RETURN and your order number in the subject to request an RMA. Please wait for return authorization before sending your item back.
Wrong part/size or change of mind: a 20% return processing fee applies, plus applicable shipping costs.
Original shipping is non-refundable. For orders shipped free, the actual outbound shipping cost is deducted from the refund. Return shipping is prepaid by the customer.
After payment capture, cancellations and refunds generally incur a 5% processing fee, except for our error, confirmed defects or confirmed carrier loss. The 5% and 20% fees do not stack; only the greater applicable fee applies. Store credit waives the 5% fee, but applicable return fees remain.

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.
