Frequently asked questions
How does the online spring quote work?
You design the spring in your browser by tuning wire diameter, outer diameter, length and coil count. The estimated price per quantity tier updates in real time — no waiting for a sales rep.

Yes. After designing, you request manufacturing and we produce exactly your specification — custom compression, extension and torsion springs, direct from the factory.
