Youxmoto Trailer Leaf Springs 3500lb Per Spring - Heavy Duty Fit

In this review of the Youxmoto trailer leaf springs the bottom line is practical: these are a direct-fit, heavy duty replacement for trailers using SW6-style springs and for owners who need straightforward load capacity and a durable steel design. The reviewer found the springs deliver the core promise - 3500 lb capacity per spring with a 6-leaf pack and a direct eye-to-eye fit of 25-1/4 in - making them a sensible choice when reliability under load and a simple swap are the priority.

Key Features

• Direct fit: Eye-to-eye length of 25-1/4 in and a 9/16 in bushing diameter mean these springs match common SW6 mounting points for quick replacement without major modifications.
• High load capacity: Rated at 3500 lb per spring, the 6-leaf pack increases load capacity compared with lighter packs and suits trailers up to a 7000 lb axle rating.
• Compact dimensions: With a free arch of 3 in and 1-3/4 in leaf width the springs fit typical trailer suspension envelopes while retaining adequate stiffness.
• Durable material: Made from heavy duty carbon steel with an extra anti-rust coating, the springs are built for transmission stability and longer service in exposed conditions.
• Simple installation: The direct replacement design and common sizing make installation straightforward for owners or mechanics replacing springs damaged by overload or corrosion.

Who It's For

These leaf springs are aimed at trailer owners and small fleet managers who need a reliable, heavy duty replacement for SW6-style springs on trailers with a 7000 lb axle. They work well for cargo trailers, equipment haulers, and other utility trailers where restoring original ride height and load capacity is the goal.

They are less suitable for custom suspension projects that require non-standard eye spacing, custom arch heights, or upgraded bushings; buyers who need premium bushings or a tuned ride may want to consider aftermarket springs with different bushing materials or a custom pack design.

Pros & Cons

Pros

• Direct replacement sizing means fast swap-in for SW6 applications with minimal modification.
• 6-leaf construction delivers higher load capacity and improved longevity under repeated heavy loads.
• Heavy duty carbon steel construction and anti-rust coating add durability for trailer use in wet or corrosive environments.
• Simple installation and maintenance reduce downtime for trailer repairs.

Cons

• Some customers report mixed quality of the supplied bushings, so you may choose to replace bushings for long-term durability.
• A small number of users noted the size can require modification for certain pace or specialty trailer frames, so verify fit before purchase.
