ARRMA Kraton 8S Spur Gear Upgrade 29T/30T MAKX029TS by GPM  [MAKX029TS]

This aftermarket spur set fits ARRMA Kraton 8S trucks and is listed as model MAKX029TS. The package includes 29T and 30T spurs in 20CrMnTi steel cut to a 1.5Mod pitch and intended as direct replacements for ARA310920 and ARA311051.

Intended application: aimed at drivers running high-output 8S systems who want a hardened spur to withstand aggressive driving and reduce long-term wear. These gears are designed to function as the main large gear in the RC drivetrain.

Practical setup steps: ensure your pinion is 1.5Mod, check and set axial alignment and backlash, and re-tighten mounting hardware after the first test run to secure mesh and prolong gear life without gearbox alterations.
