Upgrade your motorcycle wheel-change setup with RFX Pro Series Rear Axle Blocks from RFX. Designed for GasGas, KTM and Husqvarna applications, these red anodized axle blocks help make rear wheel installation faster while supporting more precise axle alignment. The RFX Pro Series design is engineered for riders and technicians who want dependable fitment, efficient maintenance and a clean factory-inspired appearance.
The integrated axle holder secures one side of the axle, allowing the axle nut to be tightened with a single spanner. Tighter manufacturing tolerances help improve fit, while the CAD-designed profile reduces unnecessary material for a lightweight solution. Constructed from CNC-machined 7075 aerospace aluminum, these axle blocks offer a durable combination of strength and performance for motocross, off-road and competition use. A laser-etched RFX logo and red color anodizing complete the professional finish.
