Double-eye or eye/eye trailers springs are all 1-3/4 inches wide and range in length from 18 to 30 inches and with trailer spring capacity ranging from 300 to 4,000 lbs.Eye diameter with bushing 9/16″ and Eye diameter without bushing: 11/16″.
Double-eye leaf springs attach to hangers that are welded onto your trailer. One end of this spring will attach directly to the hanger with a suspension bolt.Leaf springs are an integral part of your trailer suspension system. The leaf springs provide the attachment points for your trailer’s axle, suspending it from the frame of your trailer. Each spring flexes to absorb road shock as you travel, allowing the axle to move somewhat independently of the rest of your trailer. This helps to reduce wear and tear on the trailer and also ensures a smooth ride. The other end will attach to shackle straps that are suspended from a hanger. These straps allow the spring to move and pivot so that it can better compensate for uneven pavement. If you have a tandem- or triple-axle trailer, the shackle straps will be attached to the equalizer that connects multiple springs. Popular Models include:
