Key Features

• OEM-specific fit — designed for AL‑KO coupling shaft assemblies, ensuring accurate alignment and safe retention.

• 
  Made from high-quality spring steel, finished with zinc plating to resist corrosion and enhance longevity, especially in wet or marine environments.

• Compact and cost-effective — priced affordably (e.g., around AUD $6), with fast shipping from QLD and supported by a 12-month manufacturer’s warranty.

• Maintains safe coupling engagement—without this, the coupling could loosen, potentially leading to unsafe towing conditions.

• Affordable yet essential—the perfect quick-fix part instead of replacing larger coupling components.
