Spur gear engineered for ARRMA 1/5 drive systems

This replacement spur is built for ARRMA 1/5 Kraton and Outcast models, matching the original 47T, module 1.0 profile while using 20CrMnTi steel to boost resistance to wear and fatigue during demanding runs. It is suitable as a spare or a stronger upgrade for heavy brushless applications on RTR and roller variants.

Installation advice: clear the gearbox and inspect mating surfaces for grit, ensure the motor pinion matches the 1.0 module pitch and tooth count, and then set backlash after installation. Retain the original shim stack where possible and avoid excessive tightening that could preload bearings.

Performance note: replacing the stock material with a higher-strength steel improves long-term durability but does not change gear ratio if the same 47T is used; tuning still focuses on pinion selection, slipper or clutch adjustments, and ESC mapping.

Ideal for racers and weekend drivers wanting a tougher spur that preserves original fit and ratio while offering increased fatigue resistance for sustained high-torque operation.

How does this gear cope with repeated high-torque runs?

The 20CrMnTi steel construction improves fatigue life compared with softer materials, helping the gear resist tooth wear over many high-load sessions.

Will heat affect its performance?

Normal drivetrain temperatures from heavy runs are accounted for by the material choice; however, keep the gearbox ventilated and avoid sustained extreme loads without checking components afterward.

Can I fit this on EXB rollers?

Yes. The 47T M1.0 profile matches the original items listed for EXB roller and RTR variants, but always verify pinion pitch alignment before full use.

Does it require any break-in?

No specialised break-in is required; inspect mesh after initial runs and retighten hardware if necessary, then recheck gear engagement.

What should I check after long runs?

After extended sessions, clear debris from the gearbox, confirm shim spacing, and visually inspect teeth for early signs of wear or chipping.
