The Vanquish Products Brass F10 Portal Knuckle Weights are a heavy-duty front axle upgrade designed to improve traction, stability, and climbing performance on compatible RC rock crawlers. Precision-machined in the USA from domestically sourced brass, these weights replace the original front portal knuckle covers while adding substantial weight low on the vehicle.
Weighing over 120 grams per side, these brass weights add more than 240 grams to the front axle. This additional weight helps lower the vehicle's center of gravity and increase front-end weight bias, keeping the front tires planted during steep climbs and technical crawling maneuvers.
Designed as a direct replacement for compatible Vanquish Products F10 portal knuckles, these weights provide a convenient way to improve weight distribution without adding external chassis weights.
