Trailer Leaf Spring 5 Leaf Double Eye 3000 lb Cap - Fits SW5

In this review of the Trailer Leaf Spring 5 Leaf Double Eye 3000 lb Cap for 6000 lb Axle Suspension, the bottom line is straightforward: this is a practical, no-frills replacement spring set for trailer owners who need a reliable 3000 lb capacity per spring to restore ride height and load support. The reviewer found it best for trailer repairs where the original SW5 fitment is required, and the single biggest reason to buy is the heavy manganese steel construction and correct dimensional match that makes installation and load support predictable.

Key Features

• 5 leaves: Provides a balanced spring pack that restores ride height and distributes trailer load across the axle.
• 25-1/4 in eye-to-eye length: Matches SW5 fitment dimensions so the springs bolt up without frame modifications when the correct size is selected.
• 3000 lb capacity per spring: Rated to support a 6000 lb axle when used as a pair, which is useful for trailers designed to that axle rating.
• 60Si2Mn manganese steel: Material choice gives greater strength and flexibility for longevity under trailer loads.
• Two-coat painted surface: Offers corrosion resistance to extend service life in typical trailer environments.

Who It's For

This product is aimed at trailer owners and DIY mechanics who need a direct replacement for damaged or worn SW5 leaf springs and who want a reasonably priced, heavy-duty pack that restores the trailer to its rated capacity. It is especially useful for utility trailers, gear haulers, and boat trailers that match the 25-1/4 in eye-to-eye dimension and require a 3000 lb spring.

It is not for automobile, truck, van, or tractor use; these springs are designed only for trailer axles. If you need springs for highway vehicles or a different axle fitment, look for parts specified for those vehicle types and confirm load ratings before buying.

Pros & Cons

Pros

• Sturdy 60Si2Mn construction gives good strength and resistance to spring fatigue.
• Correct SW5 dimensions and 25-1/4 in eye-to-eye length make fitment straightforward for matching trailers.
• Painted finish helps resist corrosion in common trailer environments.
• Rated 3000 lb per spring restores trailer capacity when paired on a 6000 lb axle.

Cons

• Hardware quality reported as mixed by some customers, so buyers may want to reuse good existing shackles and bolts when possible.
• Not intended for any cars, trucks, vans, or tractors, so fitment is strictly limited to compatible trailers.
