Key Features & Benefits
- Greaseable design — built-in grease nipple allows lubrication of the shackle pivot point without disassembly, reducing wear and extending bushing life.
- 9/16″ x 3.5″ diameter — matches standard Australian trailer shackle plates with 1/2″ 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 R5205A greaseable shackle pin for trailers where you want to extend bushing life between services. The grease nipple allows you to pump fresh grease into the pivot point without removing the pin. For the solid (non-greaseable) version, see R5205.
