Buying Guide
What should you consider when choosing tandem axle trailer components?
- Trailer weight class: Match suspension parts to the axle rating (3,500–7,000 lb ranges are common). Selecting components with higher ratings provides margin for growth or heavier loads.
- Leaf spring size and mounting: Confirm eye-to-eye length, height, width, and bushing diameter to ensure proper fit and clearance with the trailer frame and tires.
- Hardware and installation: Some kits include all hardware; others require separate fasteners or welding. Plan for compatible mounting methods with your trailer.
- Protection and durability: Seals, rust protection, and anti-corrosion coatings prolong life in harsh outdoor environments.
- Bearings and hubs: For hub kits, verify bearing numbers and axle compatibility to avoid misfits and ensure proper rotation and longevity.
