Ohuhu 2" Receiver Adapter for 4x4 RV Bumper — Bolt-On Steel 2x2 Hitch, 3,500 lb Capacity

The Ohuhu RV Bumper Hitch 2" Receiver Adapter is a bolt-on steel 2" x 2" receiver that converts a 4" x 4" bumper into a sturdy towing or rack mount with included hitch pin and rubber cover.

This compact receiver adapter lets you add a functional 2" hitch to compatible bumpers without cutting, welding, or complex fabrication. Built from heavy-gauge steel and finished with E-coat plus black powder coating, the unit is made to resist corrosion while handling everyday hauling needs. It ships with a 5/8" hitch pin and a rubber cap so you can secure accessories or protect the receiver opening when not in use.

How easy is installation and what tools do I need?

Installation is designed to be straightforward for anyone comfortable with basic hand tools. There’s no welding required — the adapter slides into a 4" x 4" bumper opening and secures with the supplied hardware and hitch pin.

• Fits 4" x 4" bumper openings engineered for 2" x 2" square tubes.
• Requires common tools like a wrench or socket set for final tightening.
• Includes 5/8" hitch pin for simple accessory retention.

What loads and towing limits should I expect?

The Ohuhu adapter is rated for a 3,500 lb gross trailer weight and a 350 lb tongue weight, with the caveat that the final safe capacity depends on the lowest-rated component in your towing setup. Use it for bike racks, cargo carriers, tire racks, and light towing accessories within those limits.

• 3,500 lb gross trailer weight rating (system-dependent).
• 350 lb maximum tongue weight—observe limits of vehicle and accessories.
• Best for cargo racks, bike carriers, and light trailers within rating.

How durable is the receiver in outdoor and salt environments?

Durability was a primary design focus: the adapter uses premium steel and a dual-layer protective finish to resist rust and abrasion. Regular inspection and simple maintenance will extend service life, especially in coastal or winter conditions where salt exposure is common.

• Premium steel core for structural strength.
• E-coat plus black powder coating for corrosion resistance.
• Rubber hitch cap included to block moisture when unused.

What accessories come with the hitch and what do they do?

The package includes a 5/8" hitch pin and a rubber cap so you can secure accessories and keep the receiver clear of dirt or moisture when it’s not in use. These small parts improve convenience and protect the receiver’s finish over time.

• 5/8" hitch pin to lock racks or carriers to the receiver.
• Rubber cap protects the opening from grime and corrosion.
• Hardware for mounting to compatible bumpers (check fit before installation).

Who this is for: The Ohuhu RV Bumper Hitch 2" Receiver Adapter is aimed at RV owners, truck and trailer users, and DIY vehicle modifiers who need a reliable 2" receiver without welding or permanent bumper modification. It’s particularly useful for people who want to carry bike racks, cargo trays, spare-tire carriers, or light trailers on vehicles with 4" x 4" bumpers and who prefer a durable, corrosion-resistant finish and included pin and cover for immediate use.
