Tough 21T Second Gear for the Mugen MTX-5

The Arrowmax AM-MTX5-T2712 is a 21T second gear made from 7075 hard aluminum, designed to strengthen the Mugen MTX-5 drivetrain. It delivers a sturdy upgrade for club-level racing and aggressive track use, reducing component fatigue over time.

Why 7075 Alloy Works Well

7075 alloy is chosen for its high tensile strength and good fatigue resistance, which helps the gear keep its profile under repeated loads. This makes it a sensible swap when you want dependable operation lap after lap.

Designed for Direct Installation

Built to match the MTX-5 specifications, this Arrowmax gear installs with minimal fuss. Precision machining ensures correct meshing and helps prevent premature tooth wear, preserving transmission efficiency.

Do I need extra shims or spacers to fit this gear?

Most MTX-5 gearboxes accept this part without additional shims, but inspect your diff and carrier clearance and use existing hardware to confirm proper mesh.

Is anodising required for performance?

Anodising helps corrosion resistance but does not significantly change strength. The part is functional as supplied; anodising is optional based on appearance preferences.

Will this gear affect gear ratios?

No. This is a like-for-like 21T replacement so overall gear ratio remains the same; benefits come from improved durability and more consistent engagement.
