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.

Conventional Springs are high-performance, aftermarket suspension springs primarily used in motorsports and motor racing. The OD (outer diameter) size and free length, along with Hyperco’s Dynamic Travel Response™ spring design, allow for optimization of the total vehicle performance on many Circle Track vehicles and applications.
Unlike Coil-Over Springs that are available in a multitude of free lengths, Conventional Springs are limited in their free length offerings, often as a result of the sanctioning bodies and rules. The Engineers at Hyperco decided to analyze the dynamic characteristics essential to Conventional Spring performance. That data resulted in the development of the Dynamic Travel Response spring design concept.
Working within the limitations and rules, the Dynamic Travel Response design allows all springs to exceed the performance requirements for travel and rate linearity, and is still designed with significantly less physical weight.
Key Benefits of Conventional Springs
More usable deflection
Less weight than standard suspension springs
2% rate linearity tolerance from 20% to 60% of deflection
4% rate linearity tolerance from 61% to 80% of deflection
Designed to fit all standard hardware
Maintain free length and rate throughout a near infinite operational life
