DarkMatterX DM-1 Ultimate Shifter Kit (Red Shift Boot) - 2008-2014 Subaru STI

The DM-1 Shifter: A New Standard

Driven by a relentless passion to elevate performance, the DM-1 Shifter is the ultimate evolution of shifting technology for the 2008-2014 Subaru STI. Handcrafted in the USA by DARKMATTERX, this complete replacement for the stock shifter assembly delivers crisp, precise gear changes every time. Designed to forge a stronger connection between driver and machine, it transforms every shift into a mechanical masterpiece.

 

Premium Kit Components

The DM-1 Ultimate Shifter Kit includes the DM-1 Shifter, DM-1 Precision Shift Arm, DM-1 Shifter Box, and an Alcantara Shift Boot. Each piece is engineered for both performance and refinement. The shifter box, built specifically for 2008–2021 STI applications, features a carbon fiber nylon body paired with closed-cell foam and rubber seals to block out heat and noise. A CNC-cut stainless plate, corrosion-resistant hardware, and a laser-engraved finish highlight its strength and design. Completing the setup, the Alcantara Shift Boot—crafted from genuine Italian Alcantara—brings an upscale, suede-like texture commonly found in high-end European sports cars.

 

Engineered for Precision

The DM-1’s design is packed with innovations that set it apart. Its chassis-mounted construction locks the shifter firmly in place for maximum stability, using factory mounting points with no modifications required. The billet aluminum centering system, featuring dual detents and a ceramic-coated torsion spring, guarantees accurate gear engagement and eliminates missed shifts. With the tool-free adjustable shift height, drivers can easily fine-tune knob position by rotating the boot collar—no disassembly needed.

Adding to its refinement, a fully integrated reverse lockout eliminates the OEM cable while improving feedback and rigidity for 5th, 6th, and reverse selection. The reinforced 1st/2nd gear stop provides a firm, confident feel, while compatibility with OEM Subaru shift knobs ensures seamless customization. Every unit is hand-assembled and tested by DARKMATTERX to meet the strictest standards of quality, performance, and longevity.
