Thule Snug Tite Hitch Lock and Anti-Rattle Device - THSTL2

Average Customer Rating:  4.8 out of 5 stars   (456 Customer Reviews)


This is a great product! I bought this product after I had my bikes stolen off my truck, while chained to the bike rack. The thieves simply undid the bolt and took it all. $300 rack, 4 bikes, and the chain. Gone. This product replaces the nut with a lock. It is easy to use and I feel secure knowing someone can’t just take it. The company was great. Quick shipping and answered all my questions.


I recently ordered a much needed replacement product from etrailer after having done business with them at least twice previously. They stock quality products and more importantly their products are priced competitively. Rather than buying a trailer hitch as an Automotive Company's OEM product, I got a much better value from etrailer. Since that time and recently when I needed a locking bolt for a bike rack, I again made a value purchase buying an "open box" product, last week. In my book, etrailer will continue to be a go-to value supplier.


Alex went the extra mile on this Thule bike rack hardware order. He provided the customer service that I assumed extinct. Now I know it is merely endangered. Alex was first rate.


Love that I can lock the bike mount onto the rear of the car and not worry about theft. The lock mechanism is lightweight yet secure.

Great lock! Have had NO attempted ‘let’s steal the bike rack’ incidents. Truthfully , I was a bit skeptical the hitch lock wouldn’t hold. Glad to say I was wrong! Small price big reward. Stable, secure and mine!!!

Ordered the Draw-Tite 24763 for my 2015 Honda Civic Sedan, and was very satisfied at the speed and detail of not only the correspondence and email between but also the shipping speed and condition of packaging. I received this in six days from start to finish of order. I did not spring for faster shipping and was satisfied with this type of time frame considering the size and weight of packaging. I also got the Thule Hitching Post TH934XTR four bike rack and THSTL2 hitch lock anti-rattle device. I had planned ahead by watching all of the great videos on etrailer and printed out some instructions from the site. I guess I shouldn't have been surprised with their attention to detail that this was unnecessary as they included a copy of the same instructions I printed in the box. The install went exactly like the instructions/videos said it would and if I hadn't been interested in getting the beauty plastic underbody piece back on I could have been done in fifteen minutes with a lift and another set of hands. All in all a very easy kit to install, and thanks to etrailer for the speed, quality, and including all the necessary hardware and instructions. 5/5 would definitely do business with again and recommend.


The product itself is fine, the concept is all wrong! If the idea is to prevent somebody from stealing your bike rack by removing a 10mm bolt (17mm head)--what this hitch lock replaces---then it overlooks the criminal mind that would see the other 2 10mm bolts that hold the rack in place. Easily removed and away goes your rack. You would need to weld those 2 bolts in place to make your rack secure with this single locking device.


Looks like it will work nicely on my Thule bike rack, but since it’s still a couple weeks before biking season begins, haven’t had a chance to use it yet.


This hitch lock is a must have if you have an expensive bike rack. This gives a piece-of-mind and save you the hassles of installing and uninstalling the bike rack. It is very easy to install.


It works great. There is no rattle and it doesn't come loose. It stays on my truck permanently.


I went through so many hitch locks before purchasing one from here and I AM SOO HAPPY WITH THIS PURCHASE. I should have purchased from Thule from the start.


I had recently purchased a Sportrack Crest 2 Locking bike rack for my 2014 Toyota Tacoma Dbl Cab. The anti seize bolt pin was not long enough for the included lock, to engage. It was almost a 1/2 inch short. I contacted Sportrack support, and was told that was the only bolt that was available for that model.

I was also told, they would bring it up at there next weekly meeting? I replied back to them with all my information of measuring my 2" hitch receiver inner and outer circumference, taking photos of the bolt pin installed, in hopes that Thule would help me find a resolve, as I was unable to use the Sportrack Hitch Lock, thus leaving my bike rack unsecured.

I got a reply back from Thule, again saying that they would bring it up at there next weekly meeting, and also said to me, that this product had been in production for 25 years or more, and it was highly doubtful, that the accessory was available. Really? How could I be the only one with this problem, surely others have run into this same problem, and I even read a couple reviews of that very fact.

A couple weeks later, no response or any support from Thule. So I decided to do my own research and try to find a resolve. Then I fould I spoke with Theresa, and explained my problem. She and I went to work looking on there website to find a replacement or suitable anti seize threaded bolt pin, that had same overall dimensions, but just a longer length.

Much to my surprise, we found the bolt, and it was longer, and looked to be able to work. Oh and guess what! Its made by THULE!! Imagine that!!

Only problem was, the end of the bolt, had a different machine cut where the lock I had would engage, and it would be a gamble trying it, even though the price was reasonable.

We found the resolve, and saw that Thule did make not only that bolt, but also they made it in a complete locking version (THSTL2), that included a bolt, lock cylinder, master key, and reg set keys, and a Thule brand lock and a nice tool to tighten up the bolt once it was threaded into the receiver and into the hitch threads.

While it was more money, I was pretty sure this would work, in replacing the useless Sportrack anti-seize threaded hitch pin and lock, that came with my Sportrack Crest 2 Locking. It arrived, and took me all of less than 5 mins to open the package, insert the tumbler, test the keys, and install the threaded bolt, and lock it with the new lock. Now my rack is secured to the hitch.

I couldn't be happier with the support I received from etrailer, and no thanks to Sportrack/Thule customer support, that they left me in the dark, with a product that obviously had a compatibility issue with my vehicles receiver size. I give 5 stars for the support I received from, who took the time to assist me.

The THSTL2 after one year of use has held up great. I have had no problems using it to secure my Sportrak Crest 2 bike rack. It helps to give the tumbler a little shot of silicone lubricant, to key it working well. Alot of road grime gets into them, and they need to be cleaned out with a cleanerlubricant spray.

I was very easy to find the part I needed on the website. The list of available options was very helpful, and I was discovered that I needed more than one part (a pin) and could get a whole assembly. The cost was great, as well! Delivery was reasonable, and the part arrived on the day promised.


Was hesitant to order but the agent that was working with me advised me that etrailer would price match a cheaper offering I was considering. I just provided a link to the cheaper price and the price match plus % of the difference was approved within an hour. Great Customer Service!!!


Had to replace lost hitch lock for my Thule bike rack. eTrailer had it in stock, clearly detailed on website. Shipped quickly, very good communication and updates from eTrailer. Very satisfied with my purchase.


etrailer helped with replacing a lost set of a Thule bike rack locking system. The kit saved money instead of ordering each part separately. This was helpfully pointed out by Stacey. Everything works perfectly. Amazing customer service considering how big etrailer is with thousands of orders going out.

This bike rack is now used with a very fine Curt receiver hitch for my Mercedes SLK320 also purchased from eTrailer.


This works great with my Thule Bike Rack. Wasn't sure I needed a locking hitch, but came back from a bike ride one time and noticed someone had opened the cover checking to see if it was locked. I live in a nice area, but I guess you never know...


The set got my Thule bike rack back where it belonged: one the car! It was easy to install and worked just as it should. So happy to be able to take my along for the ride.


After slightly over a month, the correct Thule hitch lock THSTL2 $[XX] is finally here with the assistance of Jennifer Customer Service Supervisor. Although the previous locks were said to be compatible, they were not! I was on the verge of returning the Thule Hitching Post Pro because the 3 prior hitch locks were not fitting properly. I'm happy to report of a happy ending.


For reasons unknown, Thule manufactures
the TH958 Parkway bike rack to attach to a standard 2" hitch with a bolt that only goes halfway through the business end of the slinger. This lock unit also only threads halfway though and you affix the keyed end on the left hand side of the TH958. This works particularly well, if you are left handed. Why the TH958 was not tapped out throughout is problematic, because if it was, then you could place the lock on the left, or, if you are right-handed, on the right.

The THSTL2 does protect the slinger section from being taken. However, this leaves the pivot section and the arm assembly vulnerable. Both sections are are affixed with hex screws and bolts that can easily be removed with two crescent wrenches.

In order to remedy the situation forget the bolts and make the attachments with the hex screws and invest in a couple of stainless steel wingnuts. In order to make sure your unit will stay yours be best prepared to break down the rack and store it inside your vehicle. The wingnuts will make the chore easier.

At 44 bucks and change it is not worth it. Perhaps Thule will one day address these issues. In the meantime, caveat emptor.

Thank you for taking the time to leave a review here Bill. The reason behind the shorter bolt is that all the bolt-in Thule hitch mounted carriers have a nut welded to the inside of the stinger portion that s into the receiver and this bolt only needs to pass through that nut to snug this up in the receiver. We found that with a longer bolt there is too much redundant tightening if the bolt were to pass all the way through, that is also why the STL2 bolt is not fully threaded. As for the locking features, these are intended to deter any theft or vandalism, as with all locks.

Highly recommend so your new bike hitch doesn't disappear when you come back from your ride.


Well built and sturdy rack. It was east to assemble and slid right into the hitch. I didn't know about the extra bar for womans bike so it was a hassle getting my wife's bike on the rack. I will be purchasing the adapter bar.


Great company to deal with. The web site is packed with items and the question and answer page very helpful. What was also very helpful, was the gentleman I spoke to when I called So happy I found this site after a 20 yr old Thule bike rack was given to me with a missing pin. I haven’t connected to my rack as of yet so I do not have a picture to post. Read all the info provided about the product as well as videos. It is so helpful. THANK YOU etrailer!!


Excellent Bike Rack. Timely delivery of product. Easy installation. Minimal parts to attach. The Rack is solid. We will be transporting our bikes for various biking events and exploration around the state. I am extremely pleased with etrailer and their staff. Very informative - Video Reviews and How To...Also ordered Bike adapter and snug tite hitch lock. Very Pleased!!


Lock bolted on very easily and locking mechanism assures me that my newly purchased Thule bike rack is secured to my hitch. Thule bike hitch lock made me feel more comfortable leaving the bike rack unattended. Thanks again to Wayne H. for superior service.

Very well,being using regularly for the past year and feel very confidant when leaving bike rack unattended while riding. George E.

I purchased a Thule hitch mounted bike rack, cable lock and Thule snug tite hitch lock. These are all great products and I have been totally pleased with their performance. We've taken a number of road-trips taking our bikes along, everything has worked beautifully and to our satisfaction. There are a lot of similar products on the market, and I'm confident these are among the best!
