3pcs Joystick 4lb Tension Stainless Steel Springs for Sanwa JLF Joysticks Pacman Games (3pcs 4lb springs)

The listing mentions Arcade1up, but assuming those use the standard Sanwa JLF joystick, these springs should work for any Sanwa JLF joystick, as it appears to work fine for the joystick in my Hori RAP N3-SA (PS3 arcade stick)There is noticeably more tension compared to the original (0.9lb?) spring the stick came with, so it now requires just a little more deliberate pressure to move, which is exactly what I was looking for.If it's your first time disassembling the joystick I recommend finding a youtube tutorial and watching it through carefully; unless you have a second set of hands to help, you'll have an easier time if you take the ball/bat top off and properly remove the joystick fixture from the case/cabinet first.There were roughly 12 individual parts involved in my arcade stick, most of which will fall off as soon as you remove the c-clip, and reassembly involved holding the plastic cap that goes on top of the spring down far enough to put the c-clip back on far enough to then grab a set of pliers to pop it back in properly. There will be plenty of "potential energy" to send something flying if your finger slips!

I'm no stranger to changing springs as I've modded several cabinets and joysticks but these springs barely fit as the diameter is a little wider than the inside of the actuator thus requires a lot of pressure to put in and once in it is much tighter/heavier than other 4lb springs. I would assume it fits better on an actual sanwa as those have a slightly bigger diameter
