Buying Guide
What to verify before buying six-leaf springs for a 7,000 lb axle
- Axle compatibility: Confirm round vs. square axle and eye-to-eye length (25-1/4″ is common for these SW6-style springs).
- Load capacity: Each spring commonly supports about 3,500 lb; multiply by the number of springs per axle to estimate total capacity.
- Leaf count and width: Six leaves, typically 1-3/4″ wide, balance strength and flex.
- Bushing diameter: Commonly 9/16″; ensure your hanger and bolts align.
- Material and coating: Carbon steel with anti-rust coating offers longevity in varying climates.
- Spring kit vs. pair: Some products are sold as pairs or sets (2 or 4 springs) per axle; plan for full axle coverage.
- Installation notes: Some kits include only springs; others add U-bolts, nuts, and other hardware. Consider what you’ll need for a complete install.
- Corrosion resistance: Painted or coated springs resist rust in outdoor storage and roadside use.
FAQ
- What does “6-leaf” mean in these trailer springs?
– It refers to the number of leaf sections in each spring, which affects load distribution and stiffness. - Are these suitable for standard 7,000 lb trailers?
– Yes, when paired with compatible axles and a total load that matches spring capacity. - Do I need a full set for both sides of the axle?
– For balanced performance, replacing springs on both sides of an axle is generally recommended. - How do I know if SW6 springs fit my trailer?
– SW6 is a common specification; verify eye-to-eye length, axle type, and bushing size against your trailer’s hardware. - Can I mix brands for a single axle?
– It’s possible, but for best balance and warranty considerations, use the same model or a matched set on each side.
