GPM Racing 20CRMNTI Steel Center Diff Gear 53T (M1.0) for Arrma 1/5 Kraton 8S (MAKX053TS)

Replacement 53-tooth center diff for ARRMA 1/5 8S

The MAKX053TS center differential gear serves as an RC-scale replacement for ARRMA 1/5 8S models. This 53-tooth, M1.0 module gear is manufactured in 20CrMnTi steel to improve wear resistance under demanding use.

The profile and tooth count match ARRMA original geometry. Hardened 20CrMnTi construction aims to extend service life with heavier brushless setups. This item replaces factory reference ARA310919 and is sold as a single pcs center diff gear for direct swap into compatible ARRMA assemblies.

Fitment advice: confirm internal diff spacing and shim stack when fitting a hardened steel gear to avoid preloading bearings or binding. Use existing diff internals where serviceable and follow standard procedures for grease and preload; the MAKX053TS is a durability-focused replacement rather than a tuning part.

A hardened 53T center diff gear offering a direct-fit replacement to preserve drivetrain integrity on ARRMA 1/5 8S vehicles in heavy-use scenarios.

What checks ensure MAKX053TS is correct for my model?

Verify the 53-tooth, M1.0 module specification and match the factory reference ARA310919 against your existing diff components before fitting.

How should I set backlash after installing this gear?

Set backlash and shim stack to the same tolerances used with the original gear, checking for smooth rotation and no bearing preload after assembly.

Is MAKX053TS compatible with aftermarket diff internals?

Compatibility depends on module and spacing; many aftermarket internals that match ARRMA 1/5 8S geometry will work, but always confirm dimensions before combining parts.

Will this gear handle repeated high-torque impacts?

The 20CrMnTi steel construction improves wear and toughness for high-load conditions, but proper installation and spacing are essential to avoid premature failure. by GPM Write Product Review Please sign in your account before you can write any review. Sign In Close
