LEAF SPRING US-1088: 1_3/4” wide, 7 Leaf, 14″ (26″) approx: 3,400 lbs.

Description

Repair or replace your trailer’s suspension with the US-1088 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. 

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.

Installation & Axle Configuration Tips

1. The US-1088 mounts to standard trailer hangers and shackles and can be used in compatible single-, tandem-, or triple-axle trailer suspensions. 
2. Tandem and triple configurations commonly use equalizers to distribute movement between axles. 
3. Depending on the trailer design, the spring may be mounted below the axle in an overslung setup or above it in an underslung configuration. 
4. Always verify axle rating, hanger spacing, spring dimensions, and manufacturer specifications before installation.
