Details

Pro Series Wheel Spacers are designed to be lighter and more durable than OEM alternatives. Manufactured from 7075-T6 aluminum and color anodized for enhanced durability, these spacers resist surface wear and minimize dirt ingress into the hub, extending bearing life. The innovative design includes a rear lip to keep the spacers securely hooked into the seals, reducing the risk of them falling out during maintenance and making wheel changes faster and more efficient. Trusted by top Grand Prix and British Motocross teams, RFX products deliver superior performance and reliability. Fast spacers constructed from 7075-T6 aluminium with a unique taper design to allow for quicker/easier wheel changes without spacer dropping out, also covers full seal to prevent dirt and mud build up
