These brass internal beadlock clamp ring wheel weights are designed for 1/10 scale RC crawlers with 1.9 inch wheels. Installed inside beadlock wheels, each ring adds low-position weight to help lower the center of gravity and improve stability, traction, and side-hill performance during crawling. CNC machined from solid brass with a smooth, precise fit, these clamp rings are built for durability and consistent performance in demanding off-road conditions. Package includes 4 brass internal beadlock clamp rings. Wheel rims and tires are not included.
