Competition-Oriented Spur Gear for Revo

The 3Racing RE-029 37T Delrin spur gear targets improved torque transfer and consistent engagement in Traxxas Revo gear trains. The Delrin material keeps mass low while providing a compliant tooth face that helps absorb transient loads during aggressive cornering and acceleration.

Material Characteristics and Load Response

Delrin exhibits low sliding friction and dimensional stability under heat, improving meshing consistency and reducing abrasive wear on mating components. This behaviour supports longer service intervals compared with harder, more brittle options.

Installation and Setup Considerations

When installing the 3Racing RE-029 spur, verify backlash and pinion spacing under static and light-loaded rotation to ensure even tooth contact. Regular inspections after high-stress runs will identify any early wear patterns so you can adjust setup or replace components proactively.

What setup checks should I perform after fitting this spur?

Check pinion-to-spur mesh, confirm there is no tight spot through the range of rotation, and run a low-speed power test to listen for irregular engagement. Make small pinion adjustments if necessary.

How does Delrin affect pinion wear versus metal spurs?

Delrin tends to be gentler on pinion teeth, often reducing abrasive wear on the mating pinion when mesh is correct, though pinion material and load still influence overall wear rates.
