Replacement Dual Force Strut for Thule Roof Box - TH14933

Average Customer Rating:  4.8 out of 5 stars   (258 Customer Reviews)

This Thule Dual Force Strut replaces a similiar part for Thule Roof Boxes and many others.


These hinges work well as replacements on the Thule Evolution double sided opening clamshell rack, but they do wear out over time. Specifically, the point at which they snap on to the metal ball on the clamshell gets worn out and won’t stay connected. I’ve replaced several of these hinges over the years, so I’d estimate they last about 3 ski seasons (I knocked the rating down from 5 stars because they wear out quicker than expected). They are inexpensive and easy to replace though… it’s just inconvenient to wait a week for replacement parts, so I bought 2 this time to have a spare. Note: I’ve found that a C-clamp or wood working clamp works well to install them. It takes a lot of force to pop them back into the metal ball.


At first, I was concerned that there's a "left" strut and "right" strut, since the thin part is on the bottom on one side and on the top on the other. But I installed it, and the box works as good as new. Thule Mountaineer Box.

As recommended in another review, I used a C-Clamp with a block of wood to pop it onto the metal ball.

etrailer shipped it out the day I ordered it, and it arrived sooner than expected.


The hinge support on my ski box failed last Thursday when I unloaded the skis at the end of a ski trip, this was all a puzzle to me, it took a moment to realize what had happened--those flimsy boxes are very unstable without these supports. Did my research, found etrailer--possibly the only source? My box is Sears Xcargo Xtreme. I didn't see that precise one on the list of Thule boxes that the part was for but some models seemed close enough--besides, there are only two supports to choose from, how wrong could I go? I paid the extra $ for Priority shipping bc I had another ski trip coming up and I need that box.

It arrived promptly, I installed it today. If you subtract the time it took to take the box off the car and return it, the repair took about 5 minutes. I used the clamp with the screw handle that another reviewer recommended, I was not sure if I would have the hand strength to use the large vise grips that the man in the video used. I am a 71 year old woman.

To my great relief, the new support worked perfectly and does seem more substantial than the original. I did buy a second one but decided to hold it in reserve, the other original seemed okay for now. (That may be a mistake). With my experience, the second one shouldn't take but about 3 minutes when that time comes. Now, off to Vermont for two more ski trips and no icy skis inside the car, which is the point of all this. Thanks, etrailer!! I have no idea what I'd have done without your excellent service.


After years of struggling with a one-elbowed Rocket Box, I snapped the two pieces of the old broken elbow off the ball joints. I pressed the replacement on using a bar clamp (and a block of wood). Now the box opens and closes much easier.



The parts are still working fine….granted I don’t use a ton and I know to be gentler with the system. But yes, it’s all good


Was a perfect fit for my Sears SV20 roof top carrier.


Great replacement for my Sears Sport SV 20 struts that were broken


Perfect replacement. Easy to install


Put these on a Thule Adventurer (I think it is the 650, but not sure as someone gave it to me). They work great. It was a little confusing at first because the existing struts "bent" towards the inside on both the left and the right side. With these, one of them will bend toward the inside and another will bend towards the outside. Hopefully looking at my pictures it will make sense. Also, I used a rubber mallet to put them on. I braced the box with my knee and gave a good whack to the strut and it went on pretty easy.

Wanted to also give props to Etrailer's web site. They had a lot of good information and helped me to find exactly what I needed. Would definitely use again.


The products work perfectly, more importantly was the assistance to determine which struts I required as my box was created by Thule for BMW in Germany. When I contacted BMW USA, they were not able to determine the appropriate part number.

Thank you Madeline O at etrailer, for helping get the correct replacement.


e-Trailer had the part I needed for my 20 year old Thule roof top ski box. Nobody else provided the info that I needed to feel confident the part would actully work on my discontinued model, but e-Trailer did. Ordering was easy. Delivery was fast.


I installed this on a Sears cargo box after reading a recommendation from one of the website threads. The part worked perfectly and I am happy to have my cargo box back in commission.


Direct fit replacement. Looks and fits like factory!


This product did not work. The smaller arm simply would not go onto the ball joint despite immense pressure. Very upset that I have to return this and find an alternative.


Looking to replace our Thule roof box carrier hinges. Etrailer customer service was extremely helpful with finding the needed hinge - our roof carrier is perfect again!


Received everything and new hinge is installed on Thule box everything was straight forward except albeit after viewing how to remove socket screws with neddle nose pliers proved to be extremely difficult. Therefore I remove complete broken hinge and was able to force out with large standard screwdriver and press fit into new hinge with small vice.


PERFECT! I have a really old (I mean VINTAGE) Thule Weekender and these new hinges were a perfect update from the old gas struts. They fit perfect and work perfect. etrailer always has fast shipping and great products and prices.


East to replace and it works great!


Shipped quickly & suprisingly etrailer has more than just trailer parts


Good service and fast delivery


The right part for repairing my aging Thule box. Shipped promptly with no hassle. Highly recommended.


Fast shipping! Will definitely order from them again.


Right part, right people! Thanks!


Shipping little bit take more time (more 2 weeks ) but the quality is good anx fit with my box. Thanks


This was an excellent and perfect replacement for my sears x20 cargo box. Shipping was way faster than anticipated. Customer service is also spot on with this company. Sent an email and quickly received a response.


Works great



I think it’s probably better than new.
