Magorfas Trailer Leaf Spring Set 4-Leaf Double Eye 25-1/4" 2,500 lb Each — Pack of 2, 60Si2Mn Steel, Corrosion-Resistant

Magorfas 4-leaf double-eye trailer spring set: two 25-1/4" springs rated 2,500 lb each for a 5,000 lb axle, built in 60Si2Mn steel with corrosion-resistant paint.

If your trailer sags, bounces or handles unevenly, replacing worn springs with the correct spec restores load capacity and safer towing. These Magorfas leaf springs are engineered for trailer use only (not for cars, trucks, vans or tractors) and come as a matched pair sized for SW4 fitment. Read on for exact dimensions, materials, and how this set addresses common trailer suspension problems.

What are the exact specs and dimensions of these leaf springs?

Each spring consists of four leaves with a manufactured eye-to-eye length of 25-1/4" and a free arch (open) height of 3". The leaves are 1-3/4" wide and 3/8" thick, and the eye diameters measure 9/16" with bushing installed and 11/16" without.

• Configuration: 4 leaves, double-eye design
• Length: 25-1/4" eye-to-eye
• Free open (arch): 3"
• Leaf width/thickness: 1-3/4" wide, 3/8" thick
• Eye diameter: 9/16" with bushing, 11/16" without

How much load can these springs support and what fitment should I check?

Each spring is rated at 2,500 lb, so the matched pair supports a 5,000 lb axle when used as specified. Always verify your trailer’s tongue weight and axle rating before purchase to avoid overloading the springs and to ensure correct safety margins.

• Per spring capacity: 2,500 lb
• Pair capacity: Designed for a 5,000 lb axle
• Intended fit: SW4 application — confirm your trailer’s leaf spring mount spacing and shackles
• Not compatible: automobiles, trucks, vans, tractors

What materials and corrosion protection are used?

Magorfas uses 60Si2Mn (manganese steel) for the leaves to combine strength, flexibility and hardenability for repeated load cycles. Each spring receives two coats of paint to improve resistance to rust and environmental wear during typical trailer use.

• Steel grade: 60Si2Mn manganese steel for toughness and springback
• Finish: dual-coat paint for enhanced corrosion resistance
• Durability: designed to resist cracking from normal trailer loads
• Maintenance tip: inspect bushings and paint periodically for longevity

How do these springs solve common trailer ride and safety issues?

Replacing fatigued, cracked or corroded springs with a matched Magorfas set restores the trailer’s designed ride height and load distribution. That reduces excessive bouncing, improves stability while towing, and helps even tire wear when installed correctly with proper shackles and U-bolts.

• Fixes sagging and uneven ride height
• Reduces excessive bouncing under load
• Helps maintain axle alignment and tire wear
• Ideal for springs damaged by overload, collision or corrosion

Who is this for: This Magorfas 4-leaf double-eye spring set is for trailer owners and fleet maintainers who need a direct-fit replacement for SW4-style suspensions on trailers rated to a 5,000 lb axle. Do not buy for passenger cars, trucks, vans or agricultural tractors; instead use these when you need a robust, specification-matched spring pair to restore load capacity and towing stability.
