Description

Generic Trailer Spring: 1_3/4” wide, 7 Leaf, 14″ (26″) approx: 4,550 lbs.
Repair or replace your trailer’s suspension with our double-eye leaf spring, also known as an eye-by-eye trailer spring, designed for reliable performance and optimum load carrying capacity on light duty trailers including RVs, campers, utility trailers, boat trailers, and equipment haulers. This is a common style of leaf spring that features an “eye” at both ends of the spring with nylon or brass bushings. This spring mounts either above or below the trailer axle and secures to standard hangers and shackles for a smooth, controlled ride. Built from heat-treated spring steel, each trailer spring is engineered to handle loads while reducing bounce, excessive friction, and sway on the roughest of roads. Whether you’re replacing worn springs, upgrading your suspension, or building a new trailer, these springs offer a perfect combination of strength, stability, and durability. These are available in a variety of leaf counts and weight ratings to match your axle capacity. Our double eye leaf springs are ideal for single, tandem, or triple axle trailer configurations.
