Barnett Transmission Parts: Decades of Drivetrain Expertise
When it comes to the transmission side of your powersports drivetrain, few names carry the weight that Barnett does. Founded in 1948 by Charlie and Afton Barnett out of a small storefront in Huntington Park, California, this family-owned brand has spent more than seven decades engineering clutch and transmission components that riders can genuinely rely on. The result is a line of transmission parts built on a foundation of American manufacturing, rigorous quality control, and friction material technology that has evolved well ahead of OEM offerings.
What Sets Barnett Apart in the Transmission Category
Barnett's transmission-related catalog is anchored by its deep expertise in clutch packs — the critical interface between your engine and gearbox. The brand offers direct-replacement and performance-upgrade clutch kits that cover an impressive range of platforms, from vintage Harley-Davidson models stretching back to the early 1940s, to modern Milwaukee-Eight Touring bikes, Indian Challenger and Pursuit models, Ducati dry-clutch platforms, and a broad range of Japanese and European off-road machines.
Where Barnett truly distinguishes itself is in friction material choice. Riders can select from three distinct friction plate formulations depending on their application:
- Kevlar friction plates — engineered for smooth, consistent engagement and excellent heat resistance, ideal for street riding and touring applications
- Carbon fiber friction plates — a high-performance option delivering aggressive grip and durability under elevated loads
- Bar-Flex friction material — Barnett's oil-resistant compound that can be run wet or dry, expanding compatibility across different primary chain case configurations
Beyond friction plates, Barnett's Scorpion clutch assemblies represent the brand's flagship performance upgrade. Machined from billet aluminum, the Scorpion design delivers twice the friction area of a stock clutch while accommodating increased horsepower loads through heavy-duty coil springs — all without requiring additional machining to the stock clutch shell. This bolt-in compatibility makes the Scorpion particularly popular among Harley-Davidson builders who want a meaningful performance improvement without custom fabrication.
Barnett also offers extra-plate clutch kits that add additional friction and steel drive plates to the stock pack, effectively increasing clutch capacity for riders who have upgraded engine output or added significant torque through cams, big-bore kits, or forced induction. Spring conversion kits are available as well, converting diaphragm-style clutches to coil-spring setups favored by performance-oriented riders for their more progressive feel and adjustability.
American Manufacturing, Built to Last
All Barnett transmission and clutch products are manufactured in the USA, with the brand maintaining strict in-house quality control throughout the production process. Multiple inspection stages during manufacturing ensure that every friction plate, steel drive plate, and clutch basket meets the tolerances that have defined the brand's reputation since its earliest days. Whether you're replacing a worn stock clutch or stepping up to a performance assembly, Barnett's transmission components are engineered to meet or exceed original equipment specifications.
