Center Differential Idler — 19 Teeth, M1.0

This replacement idler gear is made for ARRMA 1/5 8S platforms and is supplied as MAKX019TS. The specification records 19 teeth with a 1.0 module and construction from 20CrMnTi steel, intended to replicate the factory center diff geometry for a straightforward replacement on the compatible ARRMA models.

Fit this idler when factory components are worn to re-establish correct gear engagement in the center differential. During reassembly, check the mating gears and bearing health to ensure proper mesh and free rotation; correct alignment prevents undue wear and preserves drivetrain predictability under load.
