2lb Sanwa JLF Tension Spring for Arcade Joystick
The 2lb tension spring can be used as a replacement for the existing spring found in the Sanwa JLF series of Joysticks. Modding your Sanwa JLF joystick with this 2lb tension spring, will give you up to 1.1lb more force, compared to the original spring. This results in a stiffer joystick, which is favored among some players who do not like the loose feel of the JLF series of joysticks.
