The 4lb 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 4lb tension spring, will give you up to 3.2lb more force, compared to the original spring. This results in a stiffer joystick, which is favoured amongst some players, who do not like the loose feel of the Sanwa JLF series of joysticks.

Product Features:
* Ideal for joystick modding
* Gives a stiffer feel to a Sanwa JLF joystick
* Up to 3.2lb more force compared to the original JLF spring

    Give it time...

    So yes, this spring is very heavy when compared to the standard spring... and that takes a few goes to get used to.
    That can be jarring at first, however I use a full meatl (and therefore heavy) bat top, which does make a difference to the feel of this spring.
    In addition to that, the spring tension does loosen slightly after a week or so of use.
    I've also got this combined with the oversized actuator and an octo gate, and I could not be happier. The very beast configuration for this stick in my opinion...

    Lets be honest, it's a couple of quid, try it out!!

    If you're looking for something less extreme, the 2lb spring is still a massive upgrade from the stock spring. Get both, see which suits your play style best.

    A good source of tension.

    Added the 4LB spring to my Sanwa JLF and stiffness increased dramatically as expected and desired. Understandably more effort is needed to move the stick but I did find my inputs became more accurate in 3rd Strike and it was a more usable J-Lever for 3D games such as VF5/Tekken due to its consistent return to neutral. For the minimal cost its worth a test for those of you that are curious.

    Very stiff spring that helps the stick back to neutral and it was especially clear when doing Akuma's Kongou Kokufetsu Zan super in 3rd Strike witch is down 3 times then punch x 3.
    Also very good tool to train the underarm muscles passivly while playing.

    Work Great for who want more Stiffness

    the spring of 4lb helps a lot and allows a better neutral when playing, facilitating in a lot of games and serves for those who find the standard spring or the 2lb spring, very soft, is for those who want precision and almost instantaneous return to neutral

    Worth getting used to

    Combined this with the Kowal oversized accuator and I love the way my otherwise stock JLF feels now. Took some getting used to and I had to work my way up with a 2lb spring before I felt comfortable with it, but I love how quickly my stick now snaps back to neutral.

    Makes the world of differnce

    Posted by Tom on 23rd Nov 2016

    Wow, I never knew how much difference just changing a spring would make. 4lbs might be too much for many - it really *does* make it a lot stiffer. I would suggest buying the 2lb and 4lb at the same time and trying both if you haven't tried changing the spring before. But for £1 you're making a massive difference to the feel of JLF. Really worth the money, if only to see how it feels.
