CURT 18-Inch Trailer Hitch Extension for 2-Inch Receiver — 3,500 lb Capacity, Gloss Black

CURT 45796 is an 18-inch hitch extension that converts a 2" x 2" receiver into added clearance for accessories and trailers, rated for 3,500 lb gross trailer weight and 350 lb tongue weight.

If a spare tire, rear bumper, or hitch-mounted accessory interferes with your trailer coupling or bike rack, adding distance between the vehicle and attachment solves the fit problem and protects your vehicle’s finish. The CURT 45796 is engineered to extend a standard 2" receiver by 18 inches using CNC-formed steel, robotic welding and a protective gloss black powder coat so the extension resists corrosion while holding rated loads.

How does this hitch extension create the clearance I need?

The 18" length increases the horizontal reach of any 2" x 2" receiver, moving the mounted accessory or trailer coupling away from the vehicle. That extra span prevents contact with bumpers, spare tires, or lift gates and makes it easier to connect a trailer without tilting ball mounts or adapters.

• Extends receiver opening outward by 18 inches for added room
• Reduces risk of scratches, dents, and interference with rear-mounted items
• Improves access when attaching couplers, bike racks, or cargo carriers

What towing loads can I safely pull with the CURT 45796?

This model carries a gross trailer weight rating of 3,500 pounds and a tongue weight rating of 350 pounds when used with properly rated hardware and a compatible vehicle and trailer. Always combine the extender’s ratings with the vehicle’s hitch and tow vehicle limits—do not exceed the lowest rated component in the towing system.

• 3,500 lb gross trailer weight capacity for typical light trailers
• 350 lb tongue weight capacity for ball mounts and cargo loads
• Intended for use only with 2" x 2" receiver applications

How is the CURT 45796 built to last outdoors and under load?

CURT manufactures this extender from precisely formed steel, with robotic welding and mechanical descaling to ensure a snug, consistent fit. A gloss black powder coat finish gives weather and UV resistance to reduce rust and chipping, extending service life through repeated use and exposure.

• CNC forming and robotic welding for dimensional accuracy and strength
• Mechanically descaled surfaces for improved paint adhesion
• Durable powder coat finish to resist corrosion, chipping, and fading

Will installation be straightforward and compatible with my existing hitch gear?

Installation is simple: slide the extender into a 2" receiver and secure it with an appropriate hitch pin or locking hitch pin (sold separately). The unit is designed to accept common 2" hitch pins and works with most ball mounts, cargo carriers, and accessory receivers built for the same size.

• Fits standard 2" x 2" trailer hitch receiver tubes
• Secures with standard 5/8" or 1/2" hitch pins depending on your setup
• Compatible with many CURT and third-party hitch-mounted accessories

Who is this for: The CURT 45796 is suited for drivers who need extra clearance for trailers or hitch-mounted gear—owners of SUVs, trucks, or vans with rear-mounted spare tires, lift gates, or aftermarket bumpers. It’s a practical choice for weekend campers, cyclists using bike racks, tradespeople hauling cargo carriers, or anyone who needs a straightforward, heavy-duty extension made in the USA to protect their vehicle and simplify hitching. Remember to match the extender’s ratings with your vehicle and trailer specifications and use the correct pin and safety chains for safe towing.
