MAXXHAUL 70017 is a heavy-duty A-frame trailer coupler engineered to accept 2" hitch balls and offer Class III/IV towing capacity with a quick-lock latch for fast, secure hookups.

This A-frame coupler is designed for utility trailers, boat trailers, campers and other haulers that require a rugged, reliable connection to a tow vehicle. Built to industry standards and rated for up to 5,000 pounds gross trailer weight, the MAXXHAUL 70017 combines a corrosion-resistant black finish, a quick-lock latch for easier hitching, and the flexibility to bolt or weld it to your trailer tongue. It works for 2" hitch balls and fits common A-frame channel widths so you can match it to many trailer builds.

How does this coupler make hitching faster and safer?

The quick-lock latch mechanism minimizes fumbling when connecting the trailer to the ball, reducing hookup time and helping ensure a secure seat. Its design holds the ball firmly once closed and resists unintended release under normal towing loads.

• Quick-lock latch for one-handed engagement while lowering the trailer
• Positive ball capture to limit slippage during towing
• Robust weld points and bolt-on holes for solid installation
• Black finish that helps slow surface corrosion

What towing capacity and ball size does the MAXXHAUL 70017 support?

This coupler is rated Class III/IV with a maximum gross trailer weight of 5,000 pounds and is made to pair with a 2" hitch ball. It’s suitable for many midsize trailer applications that fall within that weight range.

• Designed for a 2" hitch ball for broad compatibility
• Class III/IV rating with up to 5,000 lb gross trailer weight
• Appropriate for utility, small camper, and boat trailers under the limit
• Meets industry SAE standards for performance and safety

Can I bolt this coupler on, or do I need to weld it?

The MAXXHAUL 70017 is built for both bolt-on and weld-on installation, so you can install it according to your trailer’s design or your preferred mounting method. Bolt-on installation offers serviceability, while welding gives a permanent, rigid connection.

• Bolt-on holes align with common A-frame trailer tongues for straightforward mounting
• Weld-on option for permanent, heavy-duty attachment where preferred
• Installation flexibility reduces the need for adapter plates in many cases
• Follow manufacturer torque and weld guidelines for safe installation

How durable is the finish and construction for outdoor use?

The coupler is coated in a black finish intended to resist rust and wear from road exposure, moisture and debris. Combined with the solid stamped and formed steel construction, this finish helps prolong service life when maintained properly.

• Black protective coating to slow oxidation and surface rust
• Stamped steel body built to withstand towing stresses
• Maintenance-friendly — occasional cleaning and touch-up preserves finish
• Designed and tested to conform with established SAE standards
