Reliable 7075 Aluminium Pinion for Tuning

Arrowmax AM-348042 brings a precision pinion option for enthusiasts focused on reliable gearing. The 7075 aluminium build gives high strength while keeping mass low to aid throttle response.

When to Use a 48P 42T Pinion

This 48P 42T size is a practical selection when making incremental changes to gear ratio. Use it to tweak acceleration or to reduce load on the motor depending on track or surface conditions.

Material Benefits and Longevity

7075 aluminium is chosen for its strength-to-weight ratio and resistance to deformation under load. That helps the pinion maintain accurate tooth profile and prolongs service life under regular use.

How can I confirm compatibility with my gearbox?

Measure your current pinion pitch and bore size then compare to the 48P specification. Also check whether your model uses a keyed shaft or grub screw to choose the right fit method.

Does the aluminium finish need treatment?

Anodising or light protective coatings can help resist corrosion, but routine cleaning and correct mesh are the primary care steps to keep the gear performing well.

Will this pinion reduce overall weight?

Compared to steel options, 7075 aluminium is lighter and can slightly reduce rotating mass, which helps with quicker spool up and more responsive acceleration.

Is this suitable for off-road and on-road use?

The 48P 42T configuration is versatile and can be used on a variety of drive setups. Always match the gear ratio to your vehicle, surface and driving style for best results.
