The KOWAL LS.ST Short Throw Mod for Seimitsu LS-33/55 Joystick is designed for the stock actuator only. Please do not attempt to use this product with oversized actuators.
Seimitsu models LS-32 and LS-40 are well known for a variety of features including their short throw distance. Smaller frame models, such as the LS-56, LS-58-01, and LS-60-01 have medium to far throw distances, as explained on slagcoin.com (opens in new window). Shortening the throw distance in these models is desired amongst both fighting game and SHMUP fans. KOWAL again returns with a simple, low-cost answer: increase the distance between the top and bottom housing. This design works with the Seimitsu LS-33 and LS-55 joysticks, which are no longer manufactured by the company.
Long Arm, Short Throw
The KOWAL LS.ST Short Throw Mod uses up to two 3mm acrylic spacers to extend the distance between the top housing and bottom portion of the joystick. The extension restricts the normal throw distance as the shaft's bottom portion hits the inside edge of the housing, but does not affect the ability to engage each of the directional microswitches. At just 6mm, the increased length does not affect the upper portion of the joystick, rather it only extends downward. Your joystick will continue to fit in most case enclosures without issue.
Because the spacers can be stacked, you can even remove one of the spacers and increase throw distance if you prefer.
The KOWAL LS.ST comes with two acrylic spacers sized to match the housing of Seimitsu LS-33 and LS-55 joysticks. In addition, a set of two 32mm long screws are provided to accomodate the increased length, used when a yellow restrictor guide is added to the joystick.

This affords a unique degree of cost control and personalization. Each unit is etched and cut on 3mm thick quality acrylic to Kowal's specifications.

- Install both KOWAL LS.ST Short Throw Mod spacer units into the top housing. Holes will line up with the small columns inside of each. As a guide, the KOWAL logo will appear at bottom left when properly installed.
- Attach the bottom portion of the joystick housing, then white restrictor plate. Use the original long screws to secure the plate.
