This anti-rattle hitch lock was recommended to me by etrailer to fit a Curt 2 bike rack. Curt does not make an anti-rattle hitch lock for their bike rack nor would they recommend one. However, etrailer provided great assistance to recommend a product that would fit. A previously purchased lock did not fit as the threads did not match. The manufacturers try to sole source their products by changing thread configurations so only their products work on their equipment. Be careful when ordering from varied suppliers to insure products work together. This product is sturdy and meets my needs to fit the Curt rack and provides security for my rack when traveling.

Ive been using the anti-rattle hitch lock for about a year now and have no problems. It works well. The bolt is strong and provides a sturdy, tight fit for the rack. Lock has been working well although have not had it in any severe weather, water, ice or dirt conditions to see if any impacts to the lock mechanism.

I purchased this to connect my new Curt Tray-style Bike Rack (model # 18085) to my new Curt Custom Fit-Class III- 2", Trailer hitch (model # 13530). All of this went on my 2008 Lexus CR350 SUV. I was concerned that was not listed to fit the Curt model hitch and bike rack but it was exactly what was needed to keep. My new equipment locked. I could not be happier. I was able to install everything by myself in minutes. Everything was a perfect fit and now I am ready to take my bikes anywhere!


Great lock for my hitch, no problems at all,keeps my bike rack safe I recommend it.


Just as expected. I wish there was away to have ordered it keyed alike to my bike rack.


This is the only hitch lock I found to fit the threads on a Curt bike rack. The lock is not as robust as I would like compared to other hitch locks but it performs as needed to further deter a potential unwanted removal. Curt does not have a hitch lock for their bike racks. Etrailer greatly assisted with matching the lock with the Curt rack


Pros:Unique product that works with the Curt 18065 rack; bolt is of decent quality.
Cons: Plastic shell on the lock falls apart in your hand; shell is not moisture-tight; sliding dirt cover is a loose piece inside the shell that falls out when the end cap is removed; keyhole faces under the car when the lock is on the left (as necessary with the Curt rack); very overpriced, especially considering the cheap plastic shell.


This is exactly what I needed. After trying a couple of 'hardware store' pin locks that didn't fit, Savanna and Amy at etrailer customer service found the right part for me.


Excellent service though the product i ordered did not fit. My fault since I did measure properly the length of the pin I need.


I needed to get this one because of the type of bike rack I have, but wanted the better version. This was not the one I desired but a pretty good second choice. I do need a second one though.


Awesome!! Online shopping at your site was very easy and having the detailed measurements right with the pictures helped out a lot. I purchased this lock to lock my new Curt bike rack onto my Subaru CrossTrec. I first contacted Curt and they said that they did not have locks. I came across your website and found this lock that fits perfectly. Item arrived a day early even with the Memorial Day Holiday. Thanks

Still going strong after a year on the vehicle. Hasn’t been a problem at all

Etrailer staff was extremely helpful in directing me to the locking hitch pin that is compatible with my bike carrier. Used it the other day and it worked perfectly!


Is what I was looking for. Easy on and off and lock works fine.


This lock works great. We keep a bike rack on our van in a parking garage while on vacation. I want to make sure that the bikes and the bike rack are secure as possible. This lock gives me peace of mind. It is quick and easy to install.


Bought this for the lock only to replace the one I lost for my SportWORKS bike rack. Sportworks was purchased by Thule, and SportRack is also owned by Thule. Confused? Thule kept much of the Sportworks design, but lowered the quality to save money. Thule changed some parts so you have to buy Thule. One of those parts is the locking hitch pin. If you have a Thule bike rack, you must use the Thule hitch pin. Luckily, I only lost the lock, not the 5/8 diameter Sportworks hitch pin. This SportRack lock is almost a perfect match for the Sportworks I lost. It looks exactly the same, except it is rectangular, while the one I lost was round. Unfortunately, it seems of lesser quality- the key cover is loose and rattles partially open, and one end of the lock is not sealed with the plastic cover because it is also used for the SportRack cable lock and that is where the cable is attached. While I may lose another lock, I probably won't lose the pin. So, I am ordering another one of these for a backup lock. Hopefully, the key cover will be tighter. I am also trying the Swagman hitch pin with 5/8" threads and see if I can use that for a second bike rack on my other vehicle.


excellent product


Did not work. Threading different then my bike rack thread. Sitting in the toolbox. Never used it.

Many bike rack manufacturers produce threaded anti-rattle locking pins for their bike racks, and most of them will only work with racks produced by that particular manufacturer. The list of racks that this lock is compatible with is provided above in the product description.

Thread pitch will not fit my bike rack threaded adaptor. Never could use it.

this hitch locking pin SR0901 is used to replace the unlockable
hitch pin came from my sport rack 2 bike carrier SR 2901, with
this locking pin I feel safer in use. And satistically from customer
response this locking pin SR0901 has no break down record
to date. ( The unlockable pin A30901 LHP have been mentioned
two times by customer due to breakage ).

This purchase was a replacement for a lock purchased at a competitor. That lock was supposed to work with our bike rack, but did not. We then purchased this lock from etrailer. The lock has worked great (just as advertised). We are very happy with both our etrailer purchases (we also purchased the bike rack from etrailer). We would recommend etrailer to a friend and will definitely purchase from them in the future.


Would have been nice to have all locks on one bike rack match. Thule made them all different. Not just a different code, I mean the keys are completely different! Now I have 3 keys for 1 rack

Thule has quite a few different lock cores. Its more secure for their customers that way an owner of a particular bike rack, can access every example of that same model.You can purchase a core kit from Thule and replace the locks so that you have a matching set on Thule products. They do not necessarily carry over to be used with Sportrack.

Great lock. Anti-rattle. Purchased Curt bike rack & etrailer hitch. Getting into bike riding for exercise. Rack came anti-rattle pin. But did not lock. Researched & seen lot of others had problems finding aftermarket locking pins with matching threads. Called & spoke with rep. Found pin & guaranteed match with Curt bike rack. Fast delivery. All worked out well. Very satisfied with customer service.


Like everything I get from etrailer, it's a great product at a reasonable price. Easy to use good instructions. Keeps my bike rack secure and tight, no annoying rattle.

After a year of service my lock still works great! We Love it!

Product works as needed! Customer service communicated in a timely and professional manner making the experience even better.


The Thule Bike Rack Thread is not metric and what you send is metric.

Unfortunately I bought it a year ago and did not use it until last weekend and had to buy a "normal" Screw to fix it.

Although Thule owns SportRack, the bike rack hitch locks from Thule and SportRack are NOT interchangeable. Since you have a Thule bike rack, youd need to go with a Thule hitch lock, which is part # THSTL2

I bought this product for a curt tray-style hitch-mounted bike rack #18084. I was nervous bc reviews said there is no anti-rattle lock made for this carrier, but came through. Dimensions were right on shown on website. So happy I can leave my bike rack mounted on my hitch and not have to worry about it being stolen.


I was so excited when this locking pin worked for my bikerack. I have tried multiple locking pins for my Curt Bike Rack and none of them fit. This is perfect and the price was half of those they sell at bike shops. The customer services was outstanding keeping me up to date on the delivery and getting the product out really fast. I intend to buy many future products from this company. Thank You
