Replace or install a leaf-spring mounting seat on a compatible 3" round trailer axle. The Husky SS300 is a formed-steel weld-on spring seat designed for 5,000–7,000 lb trailer axle applications.
The Husky SS300 provides the mounting surface between a compatible 3" round trailer axle and the leaf spring. Its formed profile matches the axle tube, while the pre-punched center hole allows proper alignment with the leaf-spring center bolt.
Designed for weld-on installation, the SS300 is commonly used with 5,200 lb, 6,000 lb, and 7,000 lb trailer axles and accommodates compatible 1-3/4" or 2" wide leaf springs.
Formed to fit compatible round trailer axle tubes measuring 3" in diameter
Designed for compatible trailer axles within the 5,000-7,000 lb capacity range
Durable steel construction provides a strong leaf-spring mounting surface
Designed to be permanently welded to the axle tube at the required spring location
Spring seats must be positioned correctly to maintain proper axle alignment and suspension geometry. Verify spring-center spacing and axle orientation before welding, and follow the axle manufacturer's approved welding procedures.
