Poweka RV Bumper Hitch Receiver Adapter 2-inch for 4"–4.5" Square Bumpers — Bolt-On, 200 lb Tongue Capacity

Poweka's 2-inch RV bumper hitch receiver adapter converts a 4"–4.5" welded square RV bumper into a stable, bolt-on mounting point for bike racks and cargo carriers.

This adapter replaces clamp-style mounts with a reinforced support-frame design that minimizes wobble and movement while carrying rear-mounted cargo. Built from high-strength steel with a black powder-coat finish, the unit bolts onto most continuous welded 4"–4.5" square bumpers without drilling or welding. It provides a secure, corrosion-resistant platform for accessories that draw up to 200 pounds of tongue weight.

How does this adapter reduce wobble compared with clamp-style mounts?

The Poweka adapter uses a reinforced support frame that hugs the bumper and transfers load forces across a broader area than narrow clamps. That extra rigidity reduces lateral and vertical play, keeping mounted racks and cargo steadier at highway speeds and on rough roads.

• Reinforced support-frame design for improved rigidity
• Bolts secure evenly along bumper face to distribute load
• Less lateral movement than single-point clamp systems

Will this fit my RV bumper and what are the installation steps?

This adapter is engineered for continuous welded square bumpers measuring roughly 4" to 4.5". Installation is straightforward and requires only basic hand tools: position the adapter, align the bolt holes, and tighten the supplied hardware.

• Fits most 4"–4.5" continuous welded square bumpers
• No drilling or welding required—bolt-on installation
• Includes mounting hardware for quick setup in minutes

What load limits and accessories are appropriate for this receiver?

The adapter is intended for cargo-only use and supports a maximum tongue weight of 200 pounds. It’s suitable for bike racks, cargo carriers, storage boxes, and similar hitch-mounted accessories but is not rated for towing trailers.

• Maximum tongue weight: 200 lbs
• Designed for bike racks, cargo baskets, and storage boxes
• Not intended or rated for towing applications

How well will it hold up to weather and road conditions?

Poweka built this adapter from high-strength steel and finished it with a black powder coat to resist rust and abrasion from road debris. The durable finish and robust construction make it a long-lasting option for seasonal and year-round use on RVs.

• High-strength steel frame for structural durability
• Black powder-coated finish for corrosion resistance
• Engineered to withstand outdoor exposure and road vibration

Who this is for: RV owners who want a stronger, more stable mounting point for rear cargo accessories without modifying the bumper. If you carry bikes, cargo baskets, or storage boxes and need a bolt-on, corrosion-resistant receiver that cuts down on shake and movement, the Poweka 2" adapter is designed for your RV setup. Measure your bumper first to ensure compatibility and remember this unit is for cargo-only applications with a 200 lb tongue weight limit.
