This product works just as advertised. It fit my bike rack perfectly and is easy to use. Of course it is brand new, but I have no reason to think it will not last for many years.

Great question. We don’t use the rack a lot, but it still is working like new after a year. More companies should seek feedback long term. After all, isn’t that the measure of a quality product?

No fault to The lock it looks to be a good product but it is a 5/8" bolt and the swingman xc2 bike rack it was associated with takes a 1/2" bolt. I'm more disappointed with the sight linking these items together making it look like it will work together. Looking back at the rack details it does not have any notes saying it takes a 1/2" bolt so how would I know? Now I have to return the lock because I have no use for it.

The Swagman XC2 requires the lock part # S64029
Locking Anti-Rattle, Threaded Hitch Pin for Swagman Hitch Racks
-- Etrailer Expert Heather A - 02/24/2022


Installed both items within 15 minutes and am quite pleased with the results. A thunderstorm rolled through, as evidenced by the pictures, so I was unable to utilize the rack. I plan on riding the Ghost Town Trail tomorrow along with a friend. I rate these items with Five Stars !


A must have for the Swagman XTC-4 bike rack. Sure, I want to protect my bikes but I needed something that would protect my $200+ bike rack, too. You need a wrench to tighten the bolt, which does a good job of keeping the rack from rattling but is a pain because you always need to have a wrench around. But that's not the fault of the lock. The lock is pretty neat in that you can rotate the key hole so it's covered up to keep mud and weather out. I'd buy it again if needed and the price here at was good.


Bought it accidentally not knowing that one came with the bike rack I purchased. However, I lost the key to that one and had to cut it off with a diamond grinder. Works great and glad I had the spare


Great product. Fit bike rack / trailer hitch just as stated. So glad I found it online.


Lisa in Customer Service was so very helpful. She noticed that in my Swagman bike rack review I needed a locking hitch pin and pointed me in the correct direction with the correct Swagman pin on E-trailer. I tried, like most, to purchase a cheap lookalike at my local hardware/superstore store. Had to take it back and contacted Lisa to send me the correct part. She did so at a very reasonable shipping cost.
Very happy with the Swagman hitch pin and the bike rack!!
Second somewhat large purchase from E-Trailer and both have been good quality and great service.
Thank you Lisa!


Love the locking mechanism for my bike rack! I have been holding off on bringing my bikes on trailer trips for fear of theft, but this will do the trick perfectly. Once again, e-trailer has come through with a terrific product managed by the best customer service staff around.


Was Impressed and comfortable continuing with purchase after my questions/concerns were handled and answered by Brandi. Really liked her follow up all the way through from order to delivery.


I really like this, works great.


solid bolt and lock assembly arrived early, well pkg'd. Exactly as advertised and the short video also helpful since original swagman bolt slightly different (uses cotter-pin instead of lock). Suggest to use a bit of grease for first time use. Locking washer added bonus. Key assembly smart design with default with having key stay with lock when lock is not on bolt.

fine except plastic cover to key fell off, not easy to put back on, does not affect functionality, may eventually corrode?

Solid piece of gear, does it job so people can not steal my bike. Swagman should make it the standard to sell the bike rack with the locking pin.


The bike rack lock works great. It keeps the rack from rocking while on the car and I don’t have to worry about the rack getting stolen. Great price and came quickly.


This is a good piece have with 4 mountain bikes on a rack anywhere of pavement. It holds very well and quiets the movement of the track to almost nothing.


Just received lock. Works great with the Swagman standup bike rack
with the 2" receiver. This lock was specifically recommended to me by
Swagman and is design for their 2" receiver.

Still works great. Very satisfied.
Liz - 01/21/2015


The locking pin is well built and definitely solidified the rack to my 2" receiver hitch.


Extremely difficult to align pin in receiver such that you can screw in the hitch pin. Besides-an identical one COMES WITH A SWAGMAN RACK SO DON'T WASTE YOUR MONEY ON A SECOND ONE! recommends this as an accessory, but is COMPLETELY UNNECESSARY! will also charge you for return shipping! What a ripoff!

The lock is listed in the Replacement Parts section on the product page. That way if an XTC4 owner loses a lock, they can come back to the product page and quickly find a link to the replacement lock.We list what is include with each rack in the product description.

Lock and anti wobble bolt work great.


I received the Locking, Threaded Hitch Pin and installed it without any problems. The Swagman Bike Rack I purchased earlier came with the Anti-Rattle Threaded Hitch Pin, but without the Lock. The Swagman company rep that I spoke to said that the lock wasn't necessary, but it gave me peace of mind to have a lock on the Threaded Hitch Pin to prevent it from being jarred loose. Also, it makes it more theft resistant. I would rather have saved the money and gotten the locking mechanism without the threaded hitch pin, since I had this already piece, but it might be beneficial for some people.

The lock itself seems to work well. It goes on without the key; you just need to push it on. The key is required to remove it.

The threaded hitch pin does keep the bike rack from wobbling around. I tried to use a regular hitch pin, but that didn't work well at all since the 2" hitch seems smaller than my 2" receiver, so there is a lot of play in it. But with the threaded hitch pin it seems to work well. The one catch is that you need a wrench or socket set to install it or to uninstall it.

Overall, I am very happy with my purchase. I think that Swagman should include this with their racks, though. Also, it would be nice if the key for the lock used the same key as the bike rack so that you wouldn't need two separate keys.


This came taped to my hitch in the blister pack. It screwed into the receiver and hitch extension very smoothly and holds the extension tight to prevent rattles. Good product.

I lost my keys for my swagman lock . How do I get a replacement?
-- comment by: Larry B - 11/18/2013

I double checked with Swagman and replacement barrel keys for their locks are not available. If the lock is currently installed, a reciprocating saw or a rotary cutting tool will be able to cut through the bolt.

This lock is the best, it works just as the ad says, it fits perfect and you feel your bike rack will be there when you come back and no noise when driving so I would say this lock is well worth the investment, thanks again etrailer RS


Great product and a quick delivery by E Trailer. Thanls


Hitch goes on and off easily.
We have
it on our RV and our bikes don't even quiver as we go down the road.
Lock is nice too.

One year later and still working great!
PETER W - 11/15/2017


Already purchased one several years ago for our Swagman bike rack to lock it on our SUV trailer hitch, so I bought another one to have on hand in our RV.


I don't know how much extra security this actually adds, but every little bit helps. Hopefully, in forcibly removing the lock, a thief will damage the bolt, preventing easy removal. I'd rather replace the bolt than the whole rack.
