Arrowmax 48P 28T 7075 Hard Pinion Gear - AM-348028

The Arrowmax AM-348028 is a 48 pitch, 28 tooth pinion gear machined from 7075 hard aluminium for use in 1/10 and similarly scaled RC cars running a 48P drivetrain. Designed for competitive and performance-oriented builds, this pinion gear delivers precise mesh with 48P spur gears and benefits from the strength and heat resistance that 7075-series aluminium offers over standard alloys. If you're gearing your car for a specific track layout or tuning your top speed against acceleration, swapping to the correct pinion tooth count is one of the most direct adjustments available.

Key Features

• Machined from 7075 hard aluminium, which is significantly stiffer and more heat-tolerant than the softer 6061 alloy commonly used in entry-level pinions
• 48 pitch (48P) tooth profile meshes with any standard 48P spur gear
• 28 tooth count sits in the mid-to-upper range for 48P pinions, suited to higher top-speed gearing setups on longer or faster track layouts
• Hard anodised finish helps resist wear at the tooth face during sustained high-rpm running
• Compact, lightweight construction keeps rotating mass low in the drivetrain

Compatible With

• Any RC car drivetrain running a 48 pitch (48P) spur gear
• Commonly used in 1/10 scale touring cars, pan cars, and on-road competition vehicles
• Compatible with standard 3.17mm (1/8 inch) motor shafts — confirm your motor shaft diameter before ordering
