Buying Guide: Key Purchase Considerations
- Load rating and trailer axle compatibility: Most options target 5200–6000 lbs axle capacity. Confirm your trailer’s axle type (round vs square) and total GVWR before selecting.
- Eye-to-eye length and bushing diameter: Ensure 25-1/4″ length and 9/16″ bushings align with your mounting hardware and frame clearances.
- Material and coating: Look for manganese steel or carbon steel with anti-rust coatings for longer life in outdoor environments.
- Included hardware: Kits often include U-bolts, tie plates, and nuts. A kit can simplify installation and ensure compatible hardware.
- Number of leaves and spring thickness: Five-leaf configurations provide a balanced mix of load capacity and ride quality; thicker leaves generally support heavier loads.
- Oxidation and corrosion resistance: Painted or plated finishes help against rust, especially on trailers exposed to weather and road salt.
- Installation notes: Some products specify horizontal nut tightening. Follow manufacturer guidance to avoid premature wear or misalignment.
