GPM Racing 20CRMNTI Steel Spur Gear 30T (M1.5) for Arrma 1/5 Kraton 8S (MAKX030TS)

MAKX030TS 30T spur gear description

The MAKX030TS is an aftermarket spur gear intended as a direct replacement for ARRMA 1/5 Kraton and Outcast platforms. This 30-tooth spur uses an M1.5 module and is manufactured from 20CrMnTi steel to enhance wear resistance and bending strength compared with softer factory alloys.

Targeted at high-output 8S BLX brushless setups, the gear supports drivetrains where durability and consistent tooth engagement are important for long runs and heavy loads. Fitment needs matching module (M1.5) and verification of pinion/spur mesh and shimming; it replaces the factory reference numbers listed below.

Use this 20CrMnTi 30T M1.5 spur when a more robust aftermarket replacement is required; confirm module and mesh during installation and inspect drivetrain alignment after the first run.

What alloy is used for the spur gear?

The gear is specified as 20CrMnTi steel, chosen to improve wear resistance and toughness for RC drivetrain applications.

What module and tooth count does this item have?

This is a 30-tooth spur with M1.5 module; ensure your pinion matches M1.5 before attempting to fit.

Does it serve as a replacement for ARRMA factory parts?

It is offered as a direct replacement for the factory references listed above; verify part numbers to confirm compatibility with your vehicle.

Any guidance for setting mesh and alignment?

Match the M1.5 module, adjust pinion-to-spur mesh to a light running clearance, check for bearing and shaft runout, and re-check after an initial test run.

Is this suitable for 8S BLX power configurations?

The material and design target higher-stress drivetrains like 8S BLX setups, but confirm the condition of the entire drivetrain before sustained high-power operation.

Will fitting require additional parts?

No extra parts are normally required if your vehicle uses M1.5 geometry, but inspect gear height and fitment and add shims if needed to achieve correct mesh. Write Product Review Please sign in your account before you can write any review. Sign In Close
