Nilight RV Bumper Hitch Receiver 2" x 2" Adapter for 4" x 4" Square Bumpers — 3,500 lb Capacity, Bolt-On Steel

Nilight's RV bumper hitch receiver is a bolt-on 2" x 2" receiver designed to mount to 4" x 4" square RV rear bumpers and support accessory loads up to 3,500 lbs gross weight (350 lb tongue weight).

This compact, heavy-duty hitch adapter converts a square RV bumper into a standard 2" receiver so you can attach bike racks, cargo carriers, and other mount-on accessories without welding. Built from carbon steel with corrosion-resistant finish and supplied with mounting hardware and a hitch cover, the unit installs with basic tools and fits most common RV bumper profiles.

How does this receiver turn my RV bumper into a 2" accessory mount?

The Nilight receiver slides over or bolts onto a 4" x 4" square bumper and provides a standard 2" opening to accept most aftermarket racks and carriers. It’s a bolt-on design so you avoid permanent welding and can reverse or remove it when not needed.

• Accepts 2" shank bike racks and cargo carriers
• Mounts to 4" x 4" square bumper tubes without welding
• Included hardware and hitch cover simplify installation

What loads and limits should I expect from this hitch?

Rated for a gross trailer weight of up to 3,500 lbs and a tongue weight up to 350 lbs, this receiver is intended for carrying accessory loads like racks and carriers, not for towing trailers. Follow the lowest-rated component guideline—your rack, fasteners, and bumper must all meet or exceed the intended load.

• 3,500 lb gross weight rating (accessory-style load capacity)
• 350 lb maximum tongue weight—observe component limits
• Not designed or certified for towing trailers

How difficult is installation, and what comes in the box?

Installation is straightforward and requires basic hand tools; the receiver is designed to bolt onto the bumper and can even be mounted upside down if needed. Nilight ships the receiver with a complete set of mounting hardware and a hitch cover so you have everything required to attach it immediately.

• Bolt-on design—no welding required
• Includes mounting bolts, washers, nuts, and hitch cover
• Simple fit process for most 4" x 4" bumpers, installable in minutes

What materials and finish protect the hitch from weather and wear?

The receiver is constructed from heavy-gauge carbon steel for strength and durability, then treated to resist corrosion for longer life on road and RV use. Regular inspection of fasteners and touch-up of any chips will help maintain long-term performance.

• Carbon steel construction for high strength
• Protective finish reduces corrosion in outdoor conditions
• Designed for repeated accessory mounting and removal

Who this is for: RV owners who want a quick, non-permanent way to add a standard 2" receiver to a 4" x 4" square rear bumper. Ideal for cyclists, weekend travelers, and anyone needing a secure mount for cargo carriers, bike racks, or other bolt-on accessories without modifying their vehicle permanently. If you plan to tow trailers, choose a product specifically rated and certified for towing.
