This technical upgrade set pairs a machined aluminium spur gear adapter with a 32 pitch, 65T steel spur gear, supplied as a 2pcs kit. Components correspond to the referenced part numbers and are intended for the Axial Racing Yeti XL chassis.
The aluminium adapter provides a rigid mounting interface between the spur and the axle/bearing carrier and is designed to ensure concentric seating. The 65T steel spur delivers the specified tooth count and 32 pitch, optimised for stable mesh and reduced deformation under load.
Installation notes: verify axial alignment and radial clearance for the 32 pitch diameter, confirm pinion engagement by hand rotation, and inspect bearing play. Maintain clean gearbox faces and correct shimming to secure consistent tooth contact and to prolong gear life.
Intended as a durable, precision-fit upgrade for Yeti XL drivetrains; follow professional mesh and alignment practices during installation.
