This single 52-tooth Delrin spur gear is supplied as 1 pcs and intended specifically for Axial Racing EXO gearboxes. It functions as a direct replacement for routine drivetrain maintenance and straightforward tuning adjustments.
The Delrin composition offers low friction and consistent dimensional stability under typical hobby loads; correct mesh and axial alignment within the EXO gearbox are critical to avoid accelerated wear. During installation confirm pinion engagement, ensure motor and gearbox shafts are parallel, and verify free rotation across full suspension travel.
Use this spur to recover tooth geometry after wear, reduce gear noise from worn components, and maintain repeatable mesh when testing alternative pinion sizes. Check associated bearings and mounting hardware for endplay or slop prior to final torqueing.
