These springs allows the stiffness of the Sanwa JLF to be modified and will enable faster return to neutral. The springs are made from carbon steel (known as music wire) and offers the best strength and deformation resistance against repeated stresses (i.e they will retain their stiffness rating for longer). The springs are manufactured in the UK to our custom specification and are not off the shelf parts.
We offer three springs:
- 1.1 x: this will make the Sanwa JLF feel 10% stiffer than stock.
- 1.6 x: this will make the Sanwa JLF feel 60% stiffer than stock.
- 2.0 x: this will make the Sanwa JLF feel 100% stiffer than stock.
