ARRMA-compatible 43T 20CrMnTi Spur MAKX043TS for Kraton Outcast by GPM  [MAKX043TS]

43-tooth Mod 1.0 steel spur for large-scale ARRMA trucks

This aftermarket 1/5-scale spur is supplied as part number MAKX043TS for use on ARRMA Kraton and Outcast platforms. Machined from 20CrMnTi steel with a Mod 1.0 profile and 43 teeth, the component matches common large-scale driveline spacing to serve as a service replacement in the gearbox spur/pinion system.

Installation guidance: mount the spur to the gearbox carrier per the chassis instructions, set correct spur-to-pinion backlash, inspect shim stacks and bearings, and confirm free, smooth rotation before first operation. Verify the motor coupling and pinion clearance relative to the 43T diameter and replace any worn fasteners during reassembly.

Performance notes: the hardened 20CrMnTi construction reduces tooth wear under powerful brushless setups, can be used to change final drive when teamed with suitable pinions, and is aimed at pilots needing a tougher replacement for aggressive off-road duties at 1/5 scale.

Use this 20CrMnTi 43T spur as a hardened replacement in 1/5 ARRMA gearboxes and always perform mesh and bearing checks during fitment.
