Thrashin Supply Manual Transmission Shift Linkage Coupling

Precision Shifting, Rider-Engineered: Thrashin Supply Shift Linkage Couplings

Thrashin Supply Co. was founded in 2014 by X Games Gold Medalist Lance Coury — a lifelong rider who brought a performance-obsessed mindset to the Harley-Davidson aftermarket. The result is a brand built from real saddle time, not a boardroom, and that perspective shows clearly in products like their manual transmission shift linkage couplings.

On a motorcycle, the shift linkage coupling is the mechanical bridge between your foot's input and the transmission's response. A sloppy or worn coupling translates into vague, unpredictable gear changes — the kind that disrupt rhythm on a canyon run or leave you hunting for a gear in traffic. Thrashin Supply approaches this otherwise overlooked component with the same attention to detail they apply to handlebars, foot controls, and floorboards.

What Sets Thrashin Supply Shift Linkage Apart

The defining engineering feature of Thrashin Supply's shift linkage design is its use of opposing threaded heim joints. This configuration allows riders to fine-tune the height of the shift peg without removing the linkage from the bike — a genuinely practical advantage that makes dialing in ergonomics a straightforward, on-the-fly process rather than a garage teardown.

In addition to the clever adjustability, these linkages are Made in the USA and include ARP hardware — the same fastener brand trusted by professional racing engine builders — ensuring a secure, durable connection that stands up to the demands of daily riding and long-distance touring alike.

Fitment Coverage for Major Harley-Davidson Platforms

Thrashin Supply offers shift linkage couplings across the most popular Harley-Davidson model families. Available options cover:

• 1999-and-newer Touring models (Baggers with forward controls)
• Softail and Dyna models equipped with forward controls
• Dyna and Softail platforms with mid-controls
• Select FXR models (with compatible hardware)

Finish options in black and chrome ensure the linkage can complement a blacked-out custom or a chrome-accented classic build equally well. Whether you're refining a purpose-built bagger or making a daily rider more comfortable, Thrashin Supply's shift linkage couplings deliver the adjustability and hardware quality that riders expect from a brand rooted in real-world motorcycle culture.
