  • Product Description

    The Crown CWL KMS-ST series, which includes the 309-MJ and 309-Helpme contains a 25A and 35A shore tension silicone grommet. Now, available separately for this model is a higher tension ST45 which offers quicker return to center, while also catering to those who simply desire more tension when playing - similar to our Sanwa JLF 2lb and 4lb springs.

    Compatible with the CWL 303, 307 and 309 series

    Crown has evolved their joystick levers over the past few years, releasing iterations of the lever under the 300 series.  This grommet, which features a black plastic pivot, is compatible with each of the levers both old and new, such as the 303-N and 303-FK, the 307 series, and more recent Crown CWL-309MJ-KMS-ST25 Joystick or Crown CWL-309Helpme-K-KMS-ST35 Joystick.


    To replace the original Crown 300 series grommet:

    1. First lift the battop and shaft from the joystick body.  To do this, you must remove the e-clip at bottom of the lever.  A mini screwdriver wedged into the e-clip often works, pulling the clip away from the shaft.  Be careful not to lose the e-clip, as it can fly off the shaft from the pressure. Lift the shaft upwards and put aside.  The actuator may also loosen from the microswitches which is normal - you can put it back on when reinstalling the e-clip.
    2. Second, remove the 4 long screws that hold the mounting plate and upper body in place. Remove the original grommet from its housing by pulling on the plastic ring with your thumb and fingers.  
    3. Now, install the new grommet by placing it in the joystick lever housing. Line up the grommet in the same orientation as the original grommet.  You should see the circular rings impressions on the grommet.  If you don't, you need to flip the grommet over.
    4. Once installed, place the upper housing onto the bottom housing, and replace the long screws into the metal plate.

    1. Best way to play k levers

      The snappiness of the grommets really helped me with wave dashing. It will take some time for muscle memory to kick in since it could be very stiff to newer users. on Nov 4th 2019

    2. Max tension = snap neutrals

      I didn`t know what to expect from Korean levers and their tension when I was purchasing my Crown 309MJ, so I decided to buy both ST-35 and ST-45 with it just in case. ST-25 was too loose from the start, so I switched to the ST-35 and used it for many months, it was amazing, so comfortable and quick. But overtime I felt that it wasn`t quick enough, some of my moves became sloppier. Don`t know was it because the grommet loosened up or just my hand readjusted. Then I went for the ST-45. Some people said it was overbearing and too much of a difference from ST-35 but I didn`t feel that way. It is stiffer indeed but not radically.
      So if you want even quicker neutrals and don`t mind tension, don`t be afraid of ST-45, it is awesome.

    3. nice resistance

      Bought this grommet for my CWL-309MJ. I much prefer it over the ST-25 grommet that came with the stick as I felt that one was a bit soft. on Nov 9th 2017
