The YTL1666T aftermarket kit combines an aluminium spur adapter with a hardened 66T 32-pitch steel spur, supplied as a 2pcs set for Axial Racing Yeti XL. It is suitable for hobbyists replacing a worn spur or experimenting with a different material pairing for tuning.
The aluminium adapter helps reduce rotating mass at the adapter interface, while the steel 66T spur concentrates durability where the teeth engage; both parts conform to the Yeti XL 32-pitch specification. Use this set for routine maintenance or as a basic tuning change.
Installation notes: install the adapter into the existing spur assembly and fit the 32-pitch 66T spur to the standard spur position on the Yeti XL drivetrain. Standard RC hand tools are appropriate; check gear mesh and runout after fitting. No extra hardware is supplied beyond the listed specifications.
This kit is a practical aftermarket choice for Axial Racing Yeti XL owners who want a 32-pitch 66T steel spur together with an aluminium adapter, giving a clear replacement and tuning option for drivetrain care.
