Buying Guide: Key Considerations For Selecting 7,000 lb Trailer Leaf Springs
- Capacity per spring and total axle capacity: Ensure the sum of springs on a tandem axle meets or exceeds the trailer’s gross weight rating. Look for springs rated at 3,500 lb per spring for 7,000 lb axles.
- Leaf count and design: A higher leaf count generally improves load distribution and durability, but adds weight. Six-leaf configurations are common for 7K axles, providing strength with reasonable weight.
- Eye-to-eye length: Match your trailer’s mounting points with the correct eye-to-eye measurement. Typical SW6 setups use 25-1/4 inch lengths, but verify your trailer’s internal dimensions.
- Free open height and leaf width: Free open height affects the clearance under the trailer, while leaf width influences stiffness and load distribution. Common values are 3 inches free open and 1-3/4 to 2 inches width.
- Bushing diameter: A 9/16 inch bushing diameter is common for standard suspensions; ensure compatibility with your shackles and hangers.
- Material and finishing: Manganese steel and coated finishes offer higher strength, corrosion resistance, and longevity in harsh environments.
- Replacement vs. kit options: Some products are direct replacements for SW6 or similar mounts, while others come as kits including U-bolts, hangers, and hardware—evaluate what your trailer requires for full installation.
- Installation considerations: Some sets include all necessary hardware for a complete swap; others require separate purchase of U-bolts, nuts, or tie plates. Review compatibility and required tools before purchase.
- Durability in varying conditions: For frequent highway use or off-road segments, prioritize springs with robust materials and coatings to minimize sag and corrosion over time.
