Axial EXO Torque-Focused 50T Delrin Spur DEX050T by GPM  [DEX050T]

Delrin 50T Spur for EXO Drivetrains

This 50-tooth Delrin spur is an aftermarket replacement intended for Axial EXO style drivetrains. The Delrin material offers reduced friction and dependable wear properties that suit scale offroad and rock crawling use on hobby-grade rigs.

Installation notes: take care aligning spur and pinion to avoid binding, set gear mesh with minimal backlash, and inspect gearbox bearings and shafts for play before finishing assembly. Delrin usually requires lighter lubrication than metal gears; a small amount of suitable grease at the shaft area can extend life. Verify motor pinion teeth and ESC/gearbox compatibility when changing spur sizes to maintain safe motor operation.

Tuning role: changing spur size shifts final drive ratio and the load on the motor. A 50T spur raises torque for slow-speed control during crawling, and can be matched with different pinions to tune acceleration and top speed for specific tracks or trails.
