dreamdragon 4-Leaf Double Eye Trailer Spring Set - Durable 1,750 lb

In this review the dreamdragon 4-Leaf Double Eye Trailer Spring Set is evaluated for trailer owners who need a reliable, trailer-specific suspension upgrade. The bottom line: these springs deliver solid load capacity and long-term durability thanks to their 60Si2Mn manganese steel construction and a 1,750 lb rating per spring, making them a straightforward fit for standard 3,500 lb axles. Installation is simplified by pre-installed nylon bushings, and the kit is clearly intended only for trailers, which keeps expectations focused and practical.

Key Features

• Load rating: Each spring is rated for 1,750 lb, providing the necessary capacity to support a standard 3,500 lb trailer axle when used as a pair.
• Material strength: Constructed from high-strength 60Si2Mn manganese steel, the springs resist wear and maintain resilience under repeated heavy loads.
• Fitment size: The 25-1/4 in eye-to-eye length and 1-3/4 in leaf width deliver a common trailer fit for many axle setups.
• Installation-ready: Pre-installed nylon bushings with a 9/16 in bushing diameter reduce installation time and reduce metal-on-metal wear.
• Compact height: A free open height of 3 in keeps ride height predictable and compatible with typical trailer frames.

Who It's For

This kit is best for trailer owners who run standard 3,500 lb axles and need a dependable, workshop-friendly replacement or upgrade for leaf springs. It suits utility trailers, small equipment trailers, and owners who prioritize durable construction and straightforward installation.

Owners of load configurations outside the 3,500 lb axle class, or those seeking springs for vehicles other than trailers, should look elsewhere; these springs are explicitly designed for trailer applications only and are packaged as a 2-piece accessory kit for trailers.
