If you’re tired of your trailer’s suspension rusting out after a few seasons, this 4-leaf spring fixes that for good. Its Dacromet finish protects the steel from corrosion caused by saltwater, road spray, and harsh weather. Tested to last up to 700 hours in continuous salt spray, it holds up far longer than standard zinc or powder-coated springs—perfect for trailers that see a lot of water or coastal air.
This spring gives your suspension the strength and flexibility it needs to handle the miles. It’s a 4-leaf, double-eye spring built from sturdy steel and measures 1-3/4" wide with a 26" eye-to-eye length. With a 2,000-lb spring capacity (4,000-lb axle rating), it’s designed to handle heavier loads while keeping the ride smooth and stable.
Old, flattened springs can throw off your trailer’s alignment and make it bounce more than it should. This replacement installs easily onto your existing hangers with standard 9/16" bolts and comes with nylon bushings already pressed in place. The setup keeps the movement quiet and cuts down on friction for cleaner, smoother travel.
Rust-proof steel means less time on upkeep and more time towing. You won’t have to repaint or coat your suspension every season just to keep it from flaking apart. Replace your springs in pairs to maintain even support, and you’ll keep your trailer tracking straight, stable, and ready for more miles.
