Slipper Leaf Spring Suspensions

Slipper Leaf Springs have an eye in one end and a reversed curve at the other end. The eye is attached to the Front Hanger with a nut and bolt. The reversed curve end of the spring is attached at the Rear Hanger with a 'keeper bolt' that keeps the spring fastened when the trailer is jacked up for servicing.

The U-Bolts are fastened to the Tie-Plates to hold the springs to the axle. The Equalizers are fastened to the Hangers and the Springs. The Leaf Spring absorbs the punishment of the road by straightening from its curved initial position. This is facilitated by the reverse curved end sliding back and forth in the Rear Hanger. Your Trailer Suspension Parts work as a moving system to give your trailer a smooth ride.
