The Exotek Losi LST 3XL Aluminum Rear Hubs are a heavy duty rear hub option for the LST 3XL. Why? Because a big truck deserves big upgrades! The precision machined aluminum is polished and anodized in blue or gun metal, and will help you drive more and wrench less, while at the same time giving your LST a custom look. Package includes M3 set screws to hold the hinge pins as added security over the e-clips.
