MICTUNING 2-1/2" to 2" Trailer Hitch Receiver Adapter — Black Aluminum, Includes Rubber-Coated Hitch Pin & Clip

This MICTUNING adapter converts a 2-1/2" Class V hitch receiver into a standard 2" receiver so you can use common bike racks, cargo carriers and other 2" accessories without replacing your receiver.

If your vehicle has a 2-1/2" (Class V) hitch but you own accessories built for the more common 2" receivers, this adapter gives you a reliable, removable solution. Constructed from high-strength aluminum with a black powder coat, the adapter resizes your opening while protecting against corrosion and scratches. A precision-welded lip and exhaust-groove alignment feature help the adapter slide in smoothly and stop at the correct depth so the pin holes line up every time. The kit includes a rubber-coated hitch pin and clip to lock the adapter in place and reduce finger discomfort when handling.

How does this adapter ensure the pin holes align correctly?

The adapter incorporates a welded lip on the edge and an exhaust-groove design that controls insertion depth and guides the tube into the correct position. That prevents the adapter from moving too far into the receiver and keeps the pin holes aligned. The result is quicker, more reliable installation and easier removal when you want to switch back to a 2-1/2" accessory.

• Welded lip stops over-insertion and locks position.
• Exhaust-groove guides the adapter during slide-in.
• Precisely sized pin hole (0.62") matches standard hitch pins.

Will this adapter resist rust and wear for outdoor use?

Yes—the adapter is made from high-strength aluminum and finished with a durable black powder coat to resist scratches, rust and corrosion in road and weather conditions. Aluminum provides a lighter weight alternative to steel while still offering strong structural support for towing accessories within the adapter’s intended limits. Regular inspection of the finish and fasteners will maintain long-term performance.

• High-strength aluminum core for corrosion resistance.
• Black powder coat protects against scratches and the elements.
• Recommended regular visual checks for wear and secure fit.

How does the included hitch pin and clip improve usability?

The package includes a rubber-coated hitch pin and clip designed for comfortable handling and a tight fit that minimizes rotation between the adapter and receiver. The rubber coating reduces finger pinching and improves grip when inserting or removing the pin. If your vehicle’s receiver has a thicker wall and the pin seems short, you can remove the soft coating to gain additional pin length.

• Rubber coating for easier, safer handling.
• Pin and clip prevent relative rotation of adapter and receiver.
• Coating removable to extend effective pin length if needed.

What are the dimensions and what comes in the box?

The adapter has an overall length of 5.5" and a pin hole diameter of 0.62", built to convert a 2-1/2" receiver opening to accept 2" accessories. The kit arrives ready to use and includes one MICTUNING 2-1/2" to 2" receiver adapter plus one hitch pin and clip. MICTUNING provides two-year after-sales support for added peace of mind.

• Overall length: 5.5" for correct insertion depth.
• Pin hole diameter: 0.62", compatible with standard hitch pins.
• Package: adapter + hitch pin and clip; two-year warranty support.

Who is this for: Drivers who own vehicles with a 2-1/2" Class V receiver but want to use widely available 2" accessories—like bike racks, cargo carriers and towing-mounted hitch tools—will benefit from this adapter. It’s also a good choice for fleet or recreational users who need a quick, removable solution without replacing the entire receiver. If you prioritize corrosion resistance, straightforward installation, and a snug, rotation-free fit, this MICTUNING adapter meets those needs while keeping changes reversible.
