Performance 21T Pinion Upgrade - Hobbywing 30820201 - 21T 5mm 48P Steel Pinion Gear for RC Models  [HW-30820201]

Hobbywing 21T pinion for tougher drivetrain duty

The Hobbywing 21T 5mm 48P Steel Pinion Gear is built to enhance 1/10th scale RC handling and longevity. Its hard anodized chrome steel construction and a 48-53HRC hardness range provide a sturdy, wear-resistant gear for demanding off-road running.

Adjust Ratio to Match Your Setup

Changing to this pinion lets you alter the gear ratio to suit mud, grass or packed dirt. A smaller tooth count gives better pulling power, while a larger tooth count improves straight-line speed, letting you tune the truck to local tracks.
