News Bulletin

A trailer is only as good as its trailer leaf springs. When leaf springs sag, crack, or lose their arch, the entire towing experience suffers — from poor ride quality and uneven tire wear to dangerous handling and potential cargo damage. Many owners put up with these issues far longer than they should.

The Problem with Worn or Low-Quality Leaf Springs

Over time, constant road vibration, heavy loads, and exposure to the elements cause leaf springs to weaken, flatten, or break. Cheap imported springs often use inferior steel and basic bushings that wear out quickly, leading to noisy operation, poor weight distribution, and reduced safety.

Why Choose EMCO USA Made Leaf Springs

EMCO USA Made Trailer Leaf Springs are engineered for superior performance and longevity. Manufactured in the USA with multiple layers of high-quality spring steel, these springs provide excellent load-carrying capacity while absorbing bumps for a smoother ride. The powder-coated finish offers strong protection against rust and saltwater corrosion.

Featured EMCO Leaf Spring Styles

Double Eye Leaf Springs with Bronze Bushings

The popular DE-SW4B-BR / SW4B-BR 4-Leaf Double Eye Spring (1,750 lbs capacity) is a customer favorite. It includes pre-installed bronze bushings for smoother articulation and longer service life compared to nylon bushings. The double eye leaf spring design offers secure mounting on both ends and excellent compatibility with most standard trailer suspension setups.

Slipper Springs

EMCO also offers high-quality slipper springs designed for trailers using shackle or slipper-type hangers. These provide reliable performance in applications where traditional double-eye springs aren’t suitable.
