Custom double torsion springs (dual-coil) — two coil bodies for higher torque and balanced loading in a compact width.
A dual-coil torsion spring (also called a double torsion spring) uses two coil bodies connected by a bridge, working together to deliver higher torque or balanced rotational force than a single-body spring of the same size. GL Springs manufactures custom dual-coil torsion springs to your exact torque, leg angle, and wind direction — in stainless, carbon, and alloy steel, IATF 16949 certified.

What is a dual-coil (double) torsion spring?
It's a torsion spring with two coil bodies joined by a bridge, so both bodies contribute torque — used when a single coil can't deliver enough force or balanced loading is needed.
How is it different from a single torsion spring?
A single torsion spring has one coil body; a dual-coil has two, giving higher torque and more balanced loading in a similar envelope.
Do you provide samples?
Yes — fast sampling is available before mass production.
Send us your torque, deflection angle, wind direction, and leg requirement — or a drawing or sample — and our engineers will recommend the optimal design with a fast quote.
