This 2-piece upgrade is engineered as an aftermarket replacement for Axial Racing Yeti XL drivetrains, supplied as a 2pcs set. The design combines a machined 32-pitch aluminium spur gear adapter with a hardened 64-tooth steel spur to provide a stiffer mounting surface and improved wear life versus typical plastic components.
The aluminium adapter maintains concentricity under load and resists deformation, while the hardened steel 64T spur is chosen for its surface hardness and longevity in demanding crawling and trail applications. The set is intended for hobbyists seeking a durable metal-on-metal gear pairing for heavier use cycles.
Installation: confirm correct spur-to-pinion mesh before closing the gearbox, verify the adapter seats on the existing Yeti XL gearbox register, and secure fasteners to recommended torque with threadlocker where applicable. After fitting, check backlash and runout to ensure optimal gear engagement.
Manufactured for upgraded drivetrain durability and consistent mesh performance in Yeti XL applications; follow standard installation checks to achieve maximum service life.
