10K-15K HD Trailer Hanger Kit for 3" Slipper Springs 

Part Number: 28-67-4-30-66-1-KIT (HAP-103-00)

This heavy-duty hanger kit provides a complete weld-on solution for mounting 3" wide slipper springs. Designed for high-capacity 10,000lb to 15,000lb axles, it ensures a secure, industrial-grade foundation for single-axle trailer suspensions.

R&P Knowledge Hub

Compatibility: Specifically engineered for 3" wide heavy-duty slipper leaf springs and 10K to 15K capacity axles (Dexter, Lippert, Rockwell American).

Vehicle / System Fit: Ideal for heavy-duty flatbeds, equipment haulers, and lowboy trailers utilizing a single-axle slipper configuration.

Installation Notes: These are weld-on hangers. Alignment is critical; ensure the hangers are perfectly square to the frame to prevent premature tire wear and tracking issues.

Performance Insight: The extra-thick steel construction is designed to withstand high-stress lateral loads typical of heavy commercial towing and off-road job site conditions.

Features

  • Universal HD Fit: Compatible with most major 3" slipper spring brands for 10K-15K axles.
  • Industrial Strength: Heavy-gauge raw steel construction for maximum weld penetration and durability.
  • Precision Fitment: Engineered to HAP-103-00 specifications for a precise, rattle-free spring seat.
  • Complete Set: Includes both front and rear hangers for a total single-axle suspension overhaul.
