The Crown/Samducksa SDL-301-DX represents Samducksa's latest joystick lever evolution, merging the sensitive control of industry standard Sanwa JLF, and the increasingly desired appeal of the Korean lever. This time, road warriors can pack their FightSticks in the slimmest of bags, as the QR series features a detachable lever.
Quick Release Shaft. Lever Design Inspired by INFILTRATION

Taking a cue from PhreakMods JLF Link, the SDL-301-DX-QR lever possesses a spring loaded shaft cover, designed to lift by pressing and pulling the shaft upward. This releases the shaft from the joystick's metal base. When the shaft is lowered onto the base, it retains an incredibly strong lock that will not loosen during gameplay. The shaft design is streamlined to resemble a typical shaft, though a bit thicker to accomodate the spring and lock mechanism.
More commonly recognized as the INFILTRATION lever, the renowned Korean professional player lent his experience and preferences to develop the SDL-301-DX into a lever that he would personally utilize in fighting game tournaments.
The SDL-301-DX also adopts the MJ style low-profile collar, allowing for compatibility with most Japanese SS joystick mounts commonly found in Fightsticks. This places the lever just a few millimeters below the panel. The low-profile collar corrects some of the control issues that are found in earlier models such as the 303-FK, which removed the collar altogether.
Shorter Shaft for Better Clearance
In 2017, the SDL-301-DX debuted with a low profile collar, similar to the Crown CWL-309MJ-KMS-ST25 Joystick. While this and its Japan-friendly mounting plate indeed allowed the Korean lever to fit in a number of Japanese-style enclosures, its shaft height still posed challenges to lower profile Fightsticks. Often the shaft would scrape against the inner housing, which affected play.
The recent 2018 model aims to address this issue by reducing the shaft height by 2.3 millimeters from the bottom. The actuator is also .95 millimeters shorter. This places the shaft further into the housing, which should provide better clearance for lower profile Fightstick enclosures. As always, it is helpful to check specifications to ensure proper fit in your specific model. Spec illustrations are available for review below the comparison chart and in the photo gallery.

301-DX Tekken Actuator
The Samducksa SDL-301-DX-S Joystick Lever (2018 Model) contains an actuator that is well regarded for 2D fighting games. Feedback from some players, however, stated that this actuator required a wider input radius to play 3D titles such as Tekken. This feedback warranted an actuator revision designed to narrow those inputs. With the assistance of Yo-O, Samducksa introduces the "iron head" actuator specifically for Iron-Fist Tekken players.
The 301-DX Tekken actuator shares the same height composition as the original actuator. Its base, however, is 2.5mm wider, leading to quicker inputs for most titles. This has a similar result to the Kowal 1mm Oversize Actuator for Sanwa JLF Series Joystick.
Octagonal Gate Included
Another departure from Korean levers is the SDL-301-DX's default use of an octagonal gate. Octagonal gates are designed to allow smoother circular control while retaining a defined corner you can feel during play. Samducksa's model is a hybrid of circular and square control, with a very subtle corner. This helps to retain the authentic feeling of a Korean lever, while introducing something new and uncommon to the line of joysticks. The gate is secured by 8 long screws, and removable.
This octagonal gate configuration is currently specific to FA's stock of the 301-QR
Available separately is the Crown SDL-301-DX Round Restrictor Plate, which offers the more common circular control of a Korean lever.
Softer and Harder Tension Grommets Available
The SDL-301-DX-S contains a 35A shore tension silicone grommer. Available for purchase separately are two rubber grommets - the white 25 tension and red 45 tension. Higher tension 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. On the other side of the spectrum is a lighter tension that is closer to Sanwa's JLF joystick lever, which remains a player favorite within the industry.
Gersung A3 Microswitch
Each SDL-301-DX utilizes the Gersung GSM-V0323A3 microswitch. This earlier model remains a solid choice amongst players, with a slightly higher tension which works well with the 301's softer 35A shore grommet.
Will it Fit My Fightstick?
While designed for use in Japanese mount-compatible Fightsticks, the 301-DX's tall construction does create difficulty when attempting to install into low-profile hardware. Documented compatibility so far:
- Razer Panthera/Atrox
- Hori VLX
- Qanba Dragon
- Hori RAP N
- MadCatz TE2 (very tight fit)
- Qanba Q4RAF
- Qanba Obsidian
- Qanba Crystal
- Hori HRAP v4 (PS4/PS3), v5 (Xbox 360/Xbox One)
Each Crown SDL is packed within its own box with padding. Some assembly is required as Samducksa separates the battop from the housing. Along with battop and shaft cover, You will receive the following separate pieces for installation:
