KAIRAY RV Bumper Hitch Receiver Adapter — 2" Receiver for 4–4.5" Beams, Powder-Coated, 200 lb Capacity

This bolt-on adapter lets you turn an empty RV rear bumper into a functional 2" square receiver without cutting or welding. Engineered for continuous welded steel bumpers between 4" and 4.5" wide, the unit clamps around the bumper with four bolts and nuts, creating a reliable mounting point for accessories designed for a 2" shank. It’s finished in a corrosion-resistant powder coat and uses full-angle welded construction for added strength over spot-welded alternatives.

How does the adapter attach to my RV bumper?

The adapter secures to the bumper using a wrap-around design with four supplied bolts and nuts. Installation requires minimal tools and no permanent modification to the bumper, so you can remove or relocate the adapter as needed.

• Fits continuous welded steel bumpers 4"–4.5" wide.
• Mounts with four bolts and nuts included in the package.
• Requires only basic hand tools for installation.
• Removable design preserves the bumper finish and integrity.

What weight and uses are appropriate for this bumper receiver?

The KAIRAY bumper adapter is built to carry accessory loads such as bike racks, cargo baskets, and hitch-mounted steps, not for towing trailers. It supports a total tongue weight capacity of 200 lbs, which covers most common RV-approved hitch mount racks and carriers.

• 200 lb total tongue weight capacity (accessory loads only).
• Suitable for bike racks, cargo carriers, hitch steps, and similar gear.

How durable is the adapter against rust and vibration on the road?

KAIRAY’s adapter is finished with a powder-coat to resist corrosion, chips, and abrasion from road debris. The receiver’s right-angle flange is fully welded to the extender tube for improved rigidity and fewer weak points compared with spot-welded designs.

• Powder-coated surface for corrosion resistance and longer life.
• Full-angle welded joint for enhanced structural stability.
• Designed to withstand normal road vibration and accessory movement.
• Packaged ready with mounting hardware included.
