Supplied as a 2pcs set, this aftermarket upgrade replaces the stock plastic adapter and spur on Axial Racing Yeti XL models. The kit combines a 32-pitch machined aluminium adapter with a hardened 64-tooth steel spur for a metal-on-metal pairing when greater toughness is wanted.
The aluminium adapter gives a stiffer mounting face to help hold the spur concentric under load, while the steel 64T spur reduces wear compared with many factory plastic gears. This combination suits trail and crawl rigs that need consistent mesh and extended service intervals.
Fitting notes: set the spur-to-pinion mesh before final gearbox closure, ensure the adapter aligns with the Yeti XL gearbox register, and use appropriate threadlocker and torque on hardware. After fitting, check backlash, runout and re-torque fasteners as part of routine tuning.
Choose this adapter and steel spur to harden drivetrain components on Yeti XL builds; always confirm mesh and fit during installation for best results.
