ARRMA Kraton Outcast Compatible Spur 43T M1.0 MAKX043TS by GPM  [MAKX043TS]

20CrMnTi 43T replacement spur for ARRMA 1/5 models

This 1/5-scale replacement spur, sold as MAKX043TS, suits ARRMA Kraton and Outcast chassis. The component is made from 20CrMnTi steel and features a Mod 1.0 profile with 43 teeth, matching the Mod 1.0 spacing used in ARRMA large-scale drivetrains. It is intended as a durable service item for spur/pinion gear trains inside the gearbox.

Fitting advice: install the spur onto the gearbox carrier following the vehicle service guide, set spur-to-pinion backlash correctly, inspect shim and bearing condition, and confirm smooth, unloaded rotation before powering up. Double-check pinion style and motor coupling clearance against the 43T diameter and replace any compromised fasteners.

Use case: the hardened 20CrMnTi spur reduces wear under sustained high torque loads, allows ratio changes when combined with different pinions, and provides a sturdy replacement for demanding off-road or stunt driving at 1/5 scale.

Select this 20CrMnTi 43T spur when a hardened replacement is needed for 1/5 ARRMA gearboxes, and carry out standard mesh and bearing checks during installation.
