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

50-Tooth Delrin Replacement Spur

This 50-tooth Delrin spur is made as a drop-in replacement for Axial EXO drivetrains. Delrin supplies a low-friction surface and good wear characteristics, making it practical for scale offroad and rock crawling rigs where smooth gear engagement is important.

Installation notes: ensure correct spur-to-pinion mesh and minimal backlash, check bearing play and shaft alignment before tightening. Delrin gears tend to need only light lubrication; apply a small amount of compatible grease at the shaft contact to limit wear. Always confirm pinion tooth count and ESC/gearbox compatibility when changing spur sizes to manage motor load safely.

Tuning role: swapping to a 50T spur alters the final drive ratio and increases torque at the wheels for slow-speed manoeuvres. Combine different pinion sizes to fine-tune acceleration and maximum speed for your chosen terrain or course.
