The Trailer Parts Outlet 7000 lb TK Tandem Axle Kit – 14K Capacity

While this is a tandem axle kit, it’s worth considering for those who want to build a triple axle setup by combining two kits or using it as a reference for a lighter-duty triple axle gooseneck trailer. This 14,000 lb capacity kit includes two 7,000 lb electric brake axles with a 4-inch drop, plus U-bolt kits, a slipper tandem hanger kit, and four 16-inch 10-ply radial tire and wheel assemblies (ST 235/80R16).

The axles feature a drop design (loose spring seats that need welding) to lower the trailer deck height, which is beneficial for loading equipment. The included tire and wheel assemblies are ready to roll, and the LED lighting kit adds safety and visibility. If you’re building a lighter triple axle gooseneck trailer, you might adapt this kit’s components, but it’s primarily designed for tandem applications.

Buyer’s Guide: What to Consider

Choosing the right triple axle gooseneck trailer parts involves several key factors. Here are five essential considerations to guide your decision.

• Capacity and Load Rating: Match the total axle capacity to your trailer's GVWR. For a triple axle, add each axle's rating (e.g., 3×7,000 lbs = 21,000 lbs) to ensure safe hauling.
• Hub Face and Spring Center: Hub face width affects wheel track and stability. Spring center must align with your trailer frame's spring hangers. Measure carefully before purchasing.
• Axle Drop and Ride Height: Drop axles lower the trailer deck, making loading easier. Underslung axles also lower ride height. Choose based on your trailer's intended use and ground clearance needs.
• Brake Type and Compatibility: Electric drum brakes are common for heavy trailers. Ensure the axle kit includes brakes or is compatible with your trailer's brake controller and wiring.
• Ease of Installation: Pre-packaged kits with welded spring seats save time. Kits with loose spring seats require welding but offer more customization. Consider your skill level and tools.

Conclusion

Selecting the best triple axle gooseneck trailer components depends on your specific needs, from total load capacity to ease of installation. The Trailer Parts Outlet kits offer complete, pre-packaged solutions for heavy and medium-duty builds, while Lippert’s hanger kit is ideal for suspension maintenance.

For a full build, the 27K capacity kit from The Trailer Parts Outlet provides everything you need in one package. If you’re upgrading an existing trailer, the Lippert hanger kit ensures reliable suspension performance. Always match components to your trailer’s GVWR and frame dimensions for safe, long-lasting results.
