Key Features & Benefits
- Greaseable design — built-in grease nipple allows lubrication of the shackle pivot point without disassembly, reducing wear and extending bushing life.
- 5/8″ x 3.5″ diameter — matches standard Australian trailer shackle plates with 9/16″ bolt holes. The UNF thread ensures compatibility with standard nyloc nuts.
- High tensile steel — manufactured from high tensile steel to withstand the constant pivoting loads that shackle pins endure during towing over rough roads.
- Includes nyloc nut — self-locking nyloc nut prevents the pin from backing out under vibration, maintaining a secure connection.
When to Use This Pin
Use the R5208 for trailers with 5/8″ shackle bolt holes. This is the larger diameter pin for heavier-duty springs. The grease nipple allows lubrication without disassembly.
