Parabolic Springs

The Fireflex Parabolic Spring is a direct replacement for O.E, designed to replace the standard spring without modifications.

Fireflex Parabolic Springs have increased spring rates and capacities to provide greater control whilst maintaining a high level of comfort.

However, Multi-leaf springs are sometimes used to replace a Parabolic Spring, this is endorsed in the cases where a parabolic spring cannot improve the vehicles’ handling and load capacities. The team at Fireflex can design and supply many styles of Multi-leaf springs for these purposes.

High carbon alloy steels are used to achieve the desired hardness required during the heat treating process, they also increase the stress range of the spring when in service.

Quality Steels – 

51CrMoV4 – High Carbon Alloy Spring Steel – Chromium, Vanadium, Molybdenum and Manganese.

50CrV4 – High Carbon Alloy Spring Steel -Chromium, Vanadium and Manganese

Spring material thickness – It can range from 16mm to 60mm in the centre and taper down to approx 12mm to 18mm on the ends
