This upgrade set provides the core rotating components used in the differential assembly of 1/18 scale Associated RC 18T models. The package includes a steel 35T differential gear and a steel 14T input gear supplied as a 2pcs set, intended for replacement or refresh during routine drivetrain maintenance and tuning.
Designed for RC-scale use, these steel gears focus on dimensional consistency and wear resistance compared to softer stock parts. They are intended to restore gear mesh integrity, reduce premature tooth wear, and offer a stable baseline when adjusting diff preload or oil weight in the differential.
Installation notes: inspect existing housings and bearings for wear before fitting, verify gear mesh and backlash under static rotation, and use threadlocker or retaining hardware as specified by the model’s service manual. These gears are compatible with typical RC differential rebuild procedures and should be handled with light lubricant where appropriate.
Use this set when rebuilding an RC18T differential to re-establish consistent tooth engagement and to support predictable diff tuning. Replace worn gears as a matched pair to maintain drivetrain balance.
