Custom High-Quality Trailer Leaf Spring for Dump Trucks
The custom high-quality Trailer leaf springs are specifically engineered for heavy-duty dump trucks, trailers, and semi-trailers operating in harsh mining, construction, and off-road transport environments.
1. Product Overview
Our custom high-quality Trailer leaf springs are manufactured from premium alloy spring steel (e.g., 60Si2Mn, 50CrV4), our leaf springs undergo precision heat treatment and shot peening to deliver maximum fatigue life, superior load-bearing capacity, and exceptional anti-sagging performance.

3. Core Advantages & Engineering Excellence
High-Strength Material Selection
Uses premium spring steel with high yield strength and fatigue limits, preventing premature snapping or permanent sagging under dynamic overload conditions.
Shot Peening & Stress Relief
Full-surface double-sided shot peening induces compressive residual stress on the leaf surface, increasing fatigue life by over 30%–50%.
Precision Camber & Load Matching
Strict CNC camber shaping and furnace temperature control ensure accurate arching, balanced load distribution between axles, and smooth vehicle handling.
Full Customization (OEM/ODM)
Tailored dimensions, eye design, leaf curvature, and surface finishes based on customer drawings, OE part numbers, or operating environments (e.g., mining dumpers, logging trailers).
