Swing Arms FAQ

Compatibility & Capacity

Q: What hitch size does the swing away hitch adapter fit?
A: It fits any 2" hitch receiver and accepts 2" hitch cargo carriers and rack attachments.

Q: Which vehicles can I use it on?
A: Any SUV, Jeep, pickup truck, van, or other vehicle with a 2" hitch receiver, as long as the combined load stays within the limits below.

Q: What is the weight capacity?
A: The adapter holds up to 500 lbs. That limit includes the weight of the carrier or rack plus everything on it.

Q: Will it reduce my hitch’s weight capacity?
A: Any swing away adapter moves the load farther from your vehicle, which increases leverage on the hitch. As a general rule, it reduces your hitch’s effective tongue weight capacity by roughly half. Never exceed the lowest of the adapter’s 500 lb rating, your hitch’s adjusted rating, and your vehicle manufacturer’s limit.

Q: What can I attach to the swing away adapter?
A: 2" hitch cargo carriers, bike racks, and similar 2" hitch accessories up to 500 lbs, including Mockins hitch cargo carriers.

Q: Can I use it with a hitch extender?
A: We do not recommend stacking a hitch extender with the swing away adapter. Extra length adds leverage, more bounce, and further reduces the weight your hitch can safely carry.

Q: Can I use it to tow a trailer?
A: No. It is designed to hold hitch-mounted carriers and racks, not for towing trailers.

Q: What are the dimensions?
A: 30.5" L x 16.5" W x 5.5" H.

Operation & Rear Access

Q: Which way does the arm swing, and how far?
A: It opens to the passenger side at a 120-degree angle for wide access to your tailgate, hatch, or rear doors.

Q: Can I open my tailgate or rear door without unloading the carrier?
A: Yes. That is the purpose of the swing away design. You can swing the loaded carrier out of the way, as long as the total load stays within the rated capacity.

Q: How does the latch work?
A: A quick latch and an internal locking mechanism hold the arm in position. Always engage the latch and confirm the arm is fully locked before driving.

Q: Will it clear my rear-mounted spare tire?
A: It depends on your vehicle. Some Jeep owners have found that the release handle needs extra clearance around a large spare tire. Measure the distance from your receiver to the tire and handle, and contact support if you are unsure.

Q: Will it block my rear camera or parking sensors?
A: A hitch carrier on the back of any vehicle can obstruct a rear camera or sensors, so check visibility after installation and rely on your mirrors when backing up.

Q: Does it swing to the driver side?
A: The adapter is designed to open to the passenger side.

Q: How much space do I need to swing it open?
A: Leave clear space beside and behind your vehicle so the loaded arm can move freely. Check for walls, curbs, and other vehicles before swinging it out.

Installation, Security & Noise

Q: How do I install the swing away adapter?
A: Slide the adapter into your 2" hitch receiver, secure it with the included curved pin and clip, and tighten the hitch stabilizer to reduce movement. Then insert your carrier or rack shank into the adapter and secure it with a pin.

Q: The pin holes do not line up on my hitch. What should I do?
A: Receiver depth varies by vehicle, and a shallow receiver can affect how the holes align. Contact Mockins support with your vehicle details before modifying any part.

Q: How do I stop the carrier from rattling?
A: The hitch stabilizer and the optional anti-wobble internal connector help reduce rattle and noise. Tighten them before every trip.

Q: How do I protect it from theft?
A: Use a hitch lock to secure the adapter to your receiver, and lock your carrier or bag to the rack.

Durability & Maintenance

Q: What is it made of?
A: Heavy-duty steel with a rust-resistant finish.

Q: How do I maintain it?
A: Rinse off road salt and dirt, lubricate the pivot and latch, and check all pins, bolts, and the stabilizer before every trip. Store the adapter indoors when not in use.

Warranty, Shipping & Returns

Q: What warranty comes with the swing away hitch adapter?
A: Products sold by Mockins are covered by a 5-Year Limited Warranty against manufacturing defects. It does not cover misuse, overloading, or normal wear.

Q: Is shipping free, and what is the return policy?
A: Shipping is free within the contiguous U.S. and Canada, and orders ship within 1 business day. You have 30 days from delivery to request a return of unused items.
