Upgrade rear-wheel service with the RFX Pro Series Rear Axle Blocks, designed to make wheel changes faster, easier and more precise. Supplied by RFX, part FXAB 50600 99BU is engineered for compatible Husqvarna, KTM and GasGas motorcycles, helping improve axle alignment while providing a secure, practical fit during maintenance.
These blue rear axle blocks feature an integrated axle holder that secures one side of the axle, allowing tightening with a single wrench. The CAD-designed profile helps reduce unnecessary material while maintaining functional strength, and tighter manufacturing tolerances support improved fit and alignment. CNC-machined from 7075 aerospace-grade aluminum, the blocks offer durable performance for workshop servicing, racing and regular motorcycle maintenance.
A laser-etched RFX logo adds a clean branded finish, while the color-anodized blue surface provides a factory-inspired appearance and helps complement the motorcycle's existing components. The RFX Pro Series design combines efficient installation, precise positioning and durable construction in a purpose-built axle-block upgrade.
