Core Specifications

Customization Available
Engineered for “precision fit” and trailer-specific demands, this kit ensures top-tier towing safety with its 3500lb rating. The 5×5.5 idler hub’s standardized dimensions work with most mainstream trailer models, but our true strength lies in full-spectrum customization to meet your unique needs. We offer tailored adjustments for hub bolt patterns (beyond 5×5.5), axle length, load capacity calibrations, and mounting configurations—whether you need a kit for a vintage trailer, a specialized utility rig, or a heavy-use fleet vehicle. We also accommodate material upgrades (e.g., corrosion-resistant finishes for marine trailers) and functional tweaks (e.g., enhanced bearing systems for long-haul towing). This level of customization ensures the kit integrates perfectly with your trailer, eliminating fitment issues and optimizing performance. It enables seamless, hassle-free replacement while tailoring your trailer’s load-handling capability to your exact use case.
