Get repeatable, numeric readings of your gear differential’s hardness so you can build, log, and exactly replicate winning setups instead of trusting "feel". That means fewer guess-and-check rebuilds and more consistent left/right and front/rear balance - helping you match handling to track grip and conditions across race weekends.

Just plug in any 5 V Micro-USB source (power bank, charger, laptop), attach the diff with the included adapter, press the button, and in 3–5 seconds you have a hard number you can record and compare. For maximum consistency, test at the same temperature - silicone oil viscosity changes with heat, and serious racers know that matters.

Precision-machined from a single block of anodized aluminum, the Diff Analyzer is only 54×28×24.8mm and 59g - small enough to toss in any pit bag or a pocket, tough enough for daily track use. Out of the box it works with all 1/10-scale gear diffs via the included 7mm hex (wheel-nut) and dogbone/pin/outdrive adapters. Optional adapters add 1/8-scale buggies/truggies and Mini-Z support, letting you standardize readings across your entire fleet.
