The replacement locking ratchet arm assembly I recently ordered was all I hoped it would be in that every part and fastener required to install it on the trailer hitch Thule 2 bike rack fit perfectly. I was very pleased that (A) it could be accomplished and (B) the parts were still available despite this particular rack being discontinued. A fine product. Many thanks. 158636

I had broken the plastic trigger on my thule sidearm. Turns out you can't just buy the trigger. You have to replace the whole arm. This fits on my thule sidearm just like the old one. Kind of a let down that it didn't come with any hardware for mounting on the swivel joint or for the wheel hook but I just used the old hardware and hook from the arm I was replacing. 271582

I damage a number of parts on my Thule rack crashing into my garage. Fortunately all of the parts that were damaged were available from etrailer The parts came quickly and in no time the rack was good as new. 433940

I bought this to replace the ratchet arm on an older Thule T2 Hitch Mount Rack to accommodate 5" snow bike and 29+ wheels. The arm is about 2" longer than the older model and makes all the difference on the fit (helps to have the wider tray for the front wheel). It measures about 27" end to center of mount versus about 25" on the older model. 458004

fast shipping, great communication with the people of etrailer. Was able to install and use in about 5 minutes, just in time for a 400 mile road trip! 652279

The Thule T2 is an excellent rack. After ten years, the tire hook rusted through and you guys had the parts to make it new again. The original screws rusted through also and the damage can't be seen since it's inside the locking handle. It's easy enough to disassemble but who knew? 646834

Bought new arms for my Thule rack to accomadate 29" wheels. Much cheaper option than buying a new rack. Arm's arrived on time from etrailer but unfortunately one had a very bent bottom bracket I had to deal with. Had to try to bend it back in place and thankfully had the tools to do so. Another buyer could have been stuck returning it. 2nd Arm came in perfect so may be a fluke. Would buy again from etrailer but giving this three stars 588511

Part is perfect. I have an original sportworks bike rack and the company sold to Thule and has been replaced by the T2. I was so happy to find the locking ratchet arm from etrailer.com which fits my rack because mine cracked and wore out. The new one is actually longer and will fit a 29r now. Im ordering another to replace the other old arm. I have upgraded for a very reasonable investment. Everything fits and works perfect. Thank you etrailer.com 583679

I ordered these locking arms after discovering my old ones would slide open even when locked. The racheting system seems to work better than the old ones (maybe just because they are new) and lock well. I was a little disappointed that they did not have the cables inside the arm, like my old ones did, but I took the cables from my old pair and made them work with these. 555918

Just what I neede and the price was right! I needed this for a rack made by a company that was purchased by Thule. I thought that I would have to buy a whole new rack after driving into tut garage with my bike on the roof, but I was able to replace the broken part with this. Perfect fit and the price was right! 274324

Ask the Experts about this Thule Accessories and Parts
Do you have a question about this Accessories and Part?


  • Is there a Longer Locking Arm for a T2 Bike Rack to Load Bikes with 29 Inch Tires
  • Replacement Locking Ratchet Arm Assembly # 753-3579 is the same one that originally came on your T2 bike rack so it would not offer any additional length. There is a longer one, # 752-1272-001, which is 31-1/2 inches long overall which is about 2 inches longer than the original. It has been reported to fit the original T2 (916 or 917) but I cannot verify that.

  • Replacement Ratchet Arm Assembly for Older Thule T2 Hitch Bike Rack
  • I spoke with my contact at Thule regarding the Locking Ratchet Arm Assembly # 753-3579 referenced in your question. He stated that it does not appear that the replacement part has had any recent upgrades, but it will also depend on which particular model T2 you currently have as to whether or not this will be compatible. This ratchet arm is designed for older Thule T2 hitch bike racks TH916, TH916XT, TH917 and TH917XT. I did also go out to the warehouse to take a look at this part and measured...

  • Replacement Ratcheting Arm for Thule T2 Bike Rack 916
  • For the original T2 916 bike rack the correct replacement locking ratchet arm is actually # 753-3579 which is the same one for the Sidearm bike racks. If you also need the hook for the arm it is # 753-3583. You may also need # 853-5960 which is the Replacement RQL Arm Bearing Half.

  • Difference Between 753357902 and 753-3579 Replacement Thule Ratchet Arms and Can I Lock Them
  • The arm part # 753-3579 replaces the ratcheting arm on the older Thule T2 bike racks that are no longer available which are the following bike racks: TH916, TH916XT, TH917, and TH917XT. The original arms on those bike racks came with locks cylinders originally so they were considered "locking" arms. However, the replacement arms do not come with a lock cylinder like the original bike rack did so you would need to use part # TH450200 as locks or use your old lock that came in the old...

  • Thule Sidearm Ratcheting Arm Will Not Stay Locked
  • This is the first time I have heard of this issue on the Thule Sidearm. The first thing I recommend checking is that the locks are seated all the way into the housing. Use the change key, # 853-1251 if you need it, to pull the locks out and put them back in. There also could be damage to the mechanism which could occur if someone tried to turn the lock beyond its natural positions, used excessive force, or if some crud got in there and gummed up the works. Similarly, if the arm was pushed...

  • Replacement Arm Assembly for Thule 591 Long Tray Classic Roof-mount Bike Rack

  • Is Cap On End Of Ratcheting Arm For Thule T2 Bike Carrier Replaceable
  • I called my contact at Thule and the cap is not available as a separate item. The Replacement Locking Ratchet Arm Assembly, part # 753-3579 is a replacement for your bike carrier if you decide you cannot use the arm you have.

  • Arm Assembly Needed for Thule T2 Classic with Cable Lock
  • The ratcheting arm assembly # 753-3579 that you referenced doesn't actually use a cable lock as the hook itself does the locking. You will need to add lock cylinders like part # TH450200 for this feature to work though. If you are wanting the arm assembly that uses the cable then you will want part # 752-1272-001 instead. I spoke with my contact at Thule who said that the cable isn't available separately because there are some springs inside that allow the cable to operate properly.

  • Hardware to Install the Replacement Locking Ratchet Arm Assembly Part # 753-3579
  • Yes, you can use your existing hardware to install the Replacement Locking Ratchet Arm Assembly part # 753-3579. However, I would go to the local hardware store and purchase a new nylon insert lock nut as they are technically a one time use only product but I am sure you would be fine using you old nut. You will also need part # 853-1251 in order to transfer the lock core over.
