Arrowmax AM-174005 AM Differential Checker — Differential inspection gauge for R/C tuning  [AM-174005]

Differential inspection tool

The Arrowmax AM-174005 AM Differential Checker is an R/C-scale inspection accessory intended to assist hobbyists and technicians during setup and maintenance of differential units. It functions as a bench aid to assess differential condition and support iterative tuning steps without implying fitment to any specific chassis.

Use is focused on evaluation and repeatable checks rather than replacement of diagnostic equipment: position the unit so the differential can be manipulated under light load, observe rotational behaviour and feel for irregularities, and record results to inform changes to internal oil, clutch plates, or rebuild choices. The tool supports workflow tasks common to differential setup and bench tuning.

This checker provides a straightforward, repeatable way to inspect differential behaviour during R/C bench tuning and maintenance, helping to document changes and guide setup decisions.
