CURT 2" Vertical Receiver Adapter — converts downward 2" to horizontal, Gloss Black, 5,000 lb capacity

The CURT 45013 vertical receiver adapter converts a downward-facing 2" receiver into a standard horizontal 2" receiver for towing or accessories with a 5,000 lb GTW and 500 lb tongue weight capacity.

Many vehicles use a downward-pointing hitch receiver so the hitch is hidden when not in use. The CURT 45013 adapter lets you plug into that vertical opening and create a conventional horizontal receiver tube, enabling standard ball mounts, cargo carriers, bike racks and other 2" shank accessories to be used without modifying your vehicle. Built with precision-forming and a protective gloss-black powder coat, this adapter balances strength and corrosion resistance for regular towing and accessory use.

How does this adapter change a vertical receiver into a horizontal one?

The adapter slides into a 2" x 2" vertical receiver shank and provides a right-angle horizontal tube sized to accept 2" shank accessories. It effectively rotates the receiver orientation so common ball mounts and hitch accessories plug in as they would on a standard rear-facing receiver. Installation requires inserting the adapter and securing with a pin and clip (not included) sized for 2" receivers.

• Fits 2" x 2" vertical receiver openings
• Provides a 2" x 2" horizontal receiver tube
• 4-1/4" overall length with 2-7/16" drop from shank to receiver
• Secures using standard 5/8" hitch pin and clip (user-supplied)

What towing and weight limits should I observe with the CURT 45013?

This adapter is rated for a maximum gross trailer weight (GTW) of 5,000 pounds and a tongue weight (TW) of 500 pounds. Those capacities are the adapter’s limits; always adhere to your vehicle’s, hitch, and trailer’s lower capacities as well. Exceeding rated weights can damage components and compromise safety.

• Gross trailer weight capacity: 5,000 lbs
• Tongue weight capacity: 500 lbs
• Check vehicle and trailer ratings before towing
• Do not exceed the lowest-rated component in your towing setup

What materials and manufacturing methods give this adapter its durability?

CURT uses CNC-forming and robotic welding followed by mechanical descaling to ensure accurate fit and clean surfaces before finishing. The unit receives a gloss black powder coat that resists rust, chipping and UV degradation to keep the adapter usable in outdoor conditions. The manufacturing process focuses on dimensional accuracy for smooth installation and long-term durability under regular towing use.

• CNC-formed steel body for consistent dimensions
• Robotic welding for strong, repeatable welds
• Mechanical descaling creates a smooth surface for coating
• Gloss black powder coat protects against corrosion and chips

How does the adapter affect fit, alignment and ride height?

The 4-1/4" overall length and 2-7/16" drop dictate the receiver location relative to your vehicle’s bumper and trailer. That drop can change trailer tongue height compared to a direct ball mount, so measure to ensure correct trailer-to-tow vehicle level and safe towing angles. Use the adapter for occasional towing or accessory use and re-evaluate fit when switching between setups.

• Overall length: 4-1/4" for compact installation
• Drop: 2-7/16" affects hitch ball height and trailer angle
• Measure tongue height before towing for level travel
• Recommend verifying clearance for rear bumper and accessories

Who is this for: Drivers who own vehicles with downward-facing 2" hitch receivers and want a dependable way to use common 2" ball mounts or hitch accessories without swapping the vehicle’s hitch. The CURT 45013 is suited to weekend trailers, cargo carriers, bike racks and other 2" shank accessories when used within its rated capacities. It’s also a good fit for owners who value precision manufacturing and a protective finish that prolongs service life in outdoor conditions.
