dreamdragon 1,750lbs 4 Leaf Springs & U-Bolt Kit for 3,500lbs Trailer

In this review of the dreamdragon 1,750lbs 4 Leaf Springs & U-Bolt Kit, the bottom line is simple: this is a practical, heavy-duty replacement spring set for owners of single-axle trailers rated around 3,500lbs who need a reliable, well-built suspension component. The reviewer found the kit stands out for its clear capacity rating and rugged construction, making it an easy choice when matching spring capacity to axle load, and it includes the hardware needed to install both springs without sourcing extras.

Key Features

• Rated capacity: Each leaf spring is rated at 1,750lbs so the pair is intended for a standard 3,500lbs trailer axle and helps distribute trailer weight correctly.
• Construction: Made from 60Si2Mn manganese steel for enhanced strength and flexibility, improving durability under repeated loads.
• Complete kit: The package includes 2 leaf springs, 4 long U-bolts, 8 hex nuts and 2 tie plates so installers get all primary hardware required for a typical replacement.
• Corrosion resistance: A two-coat painted surface provides added protection from rust and road exposure for longer service life.
• Compact dimensions: With an eye-to-eye length of 25-1/4in and a free open height of 3in, the springs fit common short-axle trailer applications without major modification.

Who It's For

This kit is best for trailer owners and DIY mechanics who have a single axle trailer with a combined axle rating close to 3,500lbs and who want a direct, capacity-matched replacement spring set. It is also suitable for fleet maintenance where consistent, stamped spring ratings and included hardware speed up repairs.

Those who should look elsewhere include owners of heavier tandem-axle trailers or trailers with nonstandard eye-to-eye dimensions; also check load rating carefully if you carry unusually light or heavy payloads since this kit is specifically intended for standard 3,500lbs axle applications.
