This aftermarket spur gear pair is a fitment option for ARRMA Kraton 8S platforms and is identified as model MAKX029TS. The two gears, 29T and 30T, are produced from 20CrMnTi steel with a 1.5Mod tooth pitch and replace factory items ARA310920 and ARA311051.
Where to use them: suited to high-output 8S Kraton builds that demand a hardened spur to minimise wear under repeated heavy loads. They act as the principal large gear within the RC drivetrain architecture.
Setup advice: check that your pinion matches 1.5Mod pitch, set axial alignment and backlash carefully, and re-tighten fasteners after the initial run to secure correct gear engagement without altering gearbox components.
As an aftermarket steel option, the MAKX029TS 29T/30T set gives Kraton 8S drivers a hardened alternative where 1.5Mod sizing and tougher material are needed for longer service life and consistent performance.
