Ducati/Aprilia Rear Sprocket Carrier Nuts – 5DSB03 DBK

Ducati/Aprilia Rear Sprocket Carrier Nuts

Upgrade your motorcycle’s rear-drive aesthetics and structural integrity with the Ducati/Aprilia Rear Sprocket Carrier Nuts (Part # 5DSB03). Fully designed and manufactured in Italy by DBK Special Parts, this premium hardware kit swaps out dull, heavy factory steel fasteners for race-inspired, CNC-machined components that blend lightweight performance with custom styling.

Key Product Features

• High-Strength Billet Ergal: Precision CNC-machined from solid 7075-T6 aluminum alloy (Ergal). This material delivers a remarkable strength-to-weight ratio, dropping unsprung rotating mass from your drivetrain without compromising structural safety.
• Increased Footprint for Maximum Strength: Engineered with a slightly enlarged outer dimension compared to standard OEM nuts. This design increases the contact surface area against the sprocket carrier, distributing clamping force more evenly to withstand high torque loads.
• Deep Surface Anodization: Features a highly durable, weather-resistant anodized finish that protects against corrosion and road grime. The laser-etched branding adds an authentic, high-end finishing touch.
• Flawless Fitment: Machined to exact M10x1.25 thread dimensions, allowing a direct, plug-and-play replacement of your original components with zero modifications required.
• Striking Color Choices: Available in deep Red, Black, or Gold anodization to create a clean accent next to your rear sprocket or aftermarket carrier hub.

Pro Installation Tip: Because drivetrain hardware is subject to intense operational heat and severe engine vibrations, always apply a calibrated torque wrench to original factory torque specifications during installation. A drop of medium-strength blue thread-locking fluid on the studs is highly recommended to secure your hardware permanently until your next sprocket change.
