Aftermarket 1/5 ARRMA Steel Spur Options

This aftermarket spur gear set is supplied as a direct-use replacement for ARRMA 1/5 platforms. The MAKX039TS range is manufactured from 20CrMnTi steel and is available in 39T, 43T, and 47T with a 1.0 Mod pitch. The steel option is intended for users seeking greater wear resistance and stability under heavy loads.

Fitment guidance: these spur gears target ARRMA 1/5 Kraton and Outcast variants listed below. Choose tooth count according to the drivetrain behaviour you want to test—lower tooth counts favour quicker throttle response, higher counts favour higher peak speed. Always match the 1.0 Mod pitch and tooth count to your pinion and gearbox prior to installation.

Installation tips: check mesh clearance against the motor pinion, examine mating surfaces and bearings for wear or endplay, and set consistent backlash. Use suitable gear grease on tooth faces and avoid over-tightening fasteners that may distort carriers or alter mesh. Hand-rotate the gearbox to confirm smooth engagement before finishing assembly.

Verify tooth count and M1.0 pitch against your existing pinion and gearbox, and follow established mesh setup practices to ensure dependable performance in high-load conditions.

How should I pick between 39T, 43T and 47T for track or bash use?

Select 39T for stronger acceleration and aggressive bashing, 47T for higher top speed runs, and 43T as a compromise. Consider motor timing and pinion size when tuning the overall drive ratio.

Will the steel spur alter drivetrain noise?

A hardened steel spur can change the acoustic signature compared with plastic or soft alloy gears; proper mesh and lubrication will minimise noise while preserving long-term durability.

Any special break-in or maintenance steps?

After installation, check mesh after a short low-power run, re-torque hardware, and periodically inspect for wear or burrs; replace bearings or carriers showing play to protect the new steel spur.

What lubrication is recommended for these gears?

Use a quality gear grease suitable for steel-on-steel contact; apply a thin, even layer to tooth faces and avoid contaminating bearings or splines with excess grease.
