The Arrowmax AM-348039 pinion caters to racers and tuners who want a durable, precise gear. Crafted from 7075 aluminium, it is designed to maintain tooth shape and deliver steady engagement on the track. Its 48P pitch and 39 teeth integrate cleanly with many spur gears for reliable power transfer.
7075 aluminium construction gives the Arrowmax pinion high fatigue resistance for repeated runs. Careful machining of the tooth form helps ensure even contact with the spur, lowering the chance of premature wear and helping drivetrain efficiency.
The 48P 39T format provides broad fitment across standard 48-pitch systems. Installation is typically quick and straightforward, making this pinion a practical swap for both tuning sessions and routine replacements.
