Axial EXO Delrin 50T Spur Gear DEX050T by GPM  [DEX050T]

50T Delrin Spur Replacement

This 50-tooth Delrin spur gear is a hobby-grade replacement made for Axial EXO platforms. The Delrin construction offers a balance of wear resistance and low friction that suits scale offroad and rock crawling setups, intended for drivetrain maintenance and tuning on remote control models.

Installation notes: align the spur and pinion accurately to prevent binding, set proper mesh with minimal backlash, and check gearbox bearings and shaft endplay before final assembly. Delrin parts usually need less lubrication than metal gears; a light smear of compatible grease at the shaft interface helps reduce wear. Confirm motor pinion tooth count and ESC/gearbox compatibility before altering spur size to avoid excess motor load.

Tuning role: changing spur tooth count modifies the drive ratio and motor load. Installing a 50T spur typically increases wheel torque for crawling and technical sections, and can be paired with different pinions to dial acceleration versus top speed for your chosen trail or course.
