dreamdragon 6 Leaf 7000lbs Tandem Trailer Axle Suspension Kit

In this review the dreamdragon 6 Leaf 7000lbs Tandem Trailer Axle Suspension Kit is assessed for trailer owners needing a straightforward, heavy-duty replacement or upgrade. The kit is built around two 3,500 lb leaf springs that pair to support standard 7,000 lb axles, and the single biggest reason to buy is the complete hardware package: springs, U-bolts, tie plates and fasteners arrive together so a competent DIYer or a small shop can replace a tandem axle leaf pack without sourcing parts separately. The review focuses on real-world fit, durability features and what to expect during installation.

Key Features

• Rated Capacity: Each leaf spring is rated at 3,500 lbs so two springs combine for reliable performance on 7,000 lb tandem axles for common trailer loads.
• Leaf Spring Dimensions: The 25-1/4' eye to eye length and 3' free open width give a standard fit for many trailer hangers and shackle setups.
• Durable Construction: The 6-leaf pack and 9/16' bushing diameter are designed for long service life under repeated loading and highway use.
• Complete Accessory Kit: Includes 4 leaf springs, 8 long U-bolts, 16 hex nuts, 16 spring washers and 4 tie plates so hardware matches the springs for a coordinated install.
• Axle U-bolt Kit Included: The 5,200-7,000 lb axle U-bolt kit contains 4 x 7' long U-bolts, 2 tie plates and 8 hex nuts sized for 3' round axles for a secure axle-to-spring clamp.

Who It's For

This kit is aimed at trailer owners with standard 7,000 lb tandem trailer axles who want a matched set of leaf springs and mounting hardware for replacement or axle rebuilds. It is a practical choice for small haulers, utility trailers, boat trailers and anyone who prefers to buy a complete suspension kit instead of separate components.

Those who should look elsewhere include owners of vehicles with uncommon axle diameters or non-standard spring eye spacing, and people who need springs rated for commercial GVWRs above 7,000 lb per axle or specialized ride control features like overload springs or air suspension.

Cons
