Frequently Asked Questions
Can This Ball Mount Be Used for Gooseneck-To-Bumper Conversions?
No; it cannot. It’s built as a bumper-style ball mount for 2-1/2-inch receivers, not a gooseneck conversion. The detached user seeking freedom should choose a dedicated gooseneck plate or welded hitch solution instead.
Does It Fit Receivers Smaller Than 2-1/2 Inches?
No; it does not fit smaller receivers. The reader is empowered to choose compatibility—they must use a 2-1/2-inch receiver. Adapting to anything smaller requires a properly rated adapter or a different mount.
Is the Ball Mount Legal for Commercial Towing Inspections?
Yes — it generally meets commercial inspection standards when used within its stated 20,000 lb gross and 2,700 lb tongue limits. Freedom hinges on proper installation, corrosion resistance, and presentation during inspection; compliance must be verified locally.
Can I Weld Accessories Directly to the Forged Shank?
No — welding accessories directly to the forged shank is discouraged; it compromises heat-treated strength and voids safety expectations. The user is advised to pursue removable, approved attachments and certified modifications to preserve safety and freedom to tow.
Does CURT Offer a Warranty or Replacement Program?
Yes — CURT backs products with a limited lifetime warranty, acting like a steadfast anchor for freedom-seeking owners. It covers defects; replacements or repairs handled through CURT support or authorized dealers, with normal wear and misuse excluded.
