4-Pack 9/16" x 3" Shackle Bolts with Locknuts – Heavy Duty Trailer Suspension Hardware – Fits Dexter & Most Leaf Spring Hangers – Replacement for Double-Eye Springs – (4 Bolts + 4 Nuts)

This kit includes four (4) 9/16" x 3" shackle bolts and four (4) matching locknuts – everything needed to service the suspension on many utility, cargo, equipment, and enclosed trailers. These bolts are used to attach double‑eye leaf springs to front or rear hangers and shackle assemblies. They act as pivot points, allowing the spring to move as the trailer travels over uneven surfaces. Replacing worn, rusted, or damaged shackle bolts helps maintain proper wheel alignment and reduces stress on bushings and hangers. Designed to fit Dexter and most other trailer axle suspension systems that use 9/16" x 3" shackle bolts. Always verify your original bolt diameter, length, and thread pitch before ordering.

• Complete 4‑Bolt Kit – Includes four shackle bolts and four locknuts, enough to replace all bolts on one standard trailer suspension (two hangers, two shackles).
• Precision 9/16" x 3" Size – Common size for light‑ to medium‑duty trailer leaf spring suspensions (2K–7K lb axles); verify fitment with your existing hardware.
• Heavy‑Duty Construction – Manufactured to withstand constant pivoting motion, road vibration, and heavy loads without premature wear or bending.
• Includes Locknuts for Secure Fastening – Matching locknuts help prevent loosening due to suspension movement; ensures safe, reliable connection.
• Direct Fit for Dexter & Most Axles – Designed as a replacement for Dexter and many other trailer axle brands using 9/16" shackle bolts; ideal for routine suspension maintenance.
