Suspension spring
Helical suspension springs for vehicles, trailers and machinery. Design the exact load and travel and quote instantly.
Recommended type and material
Suspensions use thick chrome-silicon or tempered wire, absorbing large loads with long fatigue life. The spring rate sets the assembly's stiffness and ride comfort.

Things to consider
- Thick wire (8–14 mm) for high axial loads.
- Chrome silicon for durability under repeated impact.
- Rate calibrated to the vehicle weight and travel.
