6-Leaf Double-Eye Trailer Spring – 3,500 lb Capacity

The Trailer Parts Pro™ 6-Leaf Double-Eye Trailer Spring is a rugged, heavy-duty suspension component designed for 7,000 lb trailer axles. With a 3,500 lb capacity per spring, it provides excellent load support and durability for equipment, car hauler, cargo, and utility trailers.

Engineered from high-strength spring steel, this leaf spring flexes to absorb road shock, reduce vibration, and ensure a smooth, level ride — even on uneven terrain. The nylon bushing allows for quieter operation and longer wear life, while the double-eye design ensures stable performance under heavy loads, and the spring mounts easily with standard hangers or a  tandem hanger kit (sold separately).
