That back-and-forth chucking you feel while towing wears on you and your trailer. These cushioned equalizers help smooth things out by absorbing road shock from both axles. You get a more controlled ride with less stress on your trailer.Upgrade from Factory Equalizers: Replaces standard cast equalizers on many tandem trailers. Fits Common Tandem Axle Setups: Works with 3,500-lb to 8,000-lb axles.
Double-eye leaf spring acts as part of a trailer's suspension system by providing an attachment point for a 3,500-lb axle. Spring flexes to resist shock and also ensures a smooth ride. Includes bushings with 9/16" inner diameter.If you have a tandem- or triple-axle trailer, the shackle straps will be attached to the equalizer that connects multiple springs. To mount this spring, you will need hangers, shackle straps, and suspension bolts. If you are simply replacing a spring, you may still have hangers welded onto your trailer.
