Hi there, I'm Michael with Today, we're gonna take a quick look at this Thule Replacement Mounting Hardware Set. This set is going to replace the quick release mounting hardware needed for your SportRack or your Thule cargo box. This will work with the SportRack Horizon, the SportRack Aero, and the SportRack Expedition. This will also work with your Thule Excursion, Thule Frontier, Thule Mountaineer, and your Thule Traveler cargo boxes. This is going to include all the hardware needed to mount all four corners of your cargo box to your roof rack crossbars.

This is going to have a maximum crossbar dimension of 1 9/16 of an inch tall and 3 3/4 of an inch wide. You can see our distance between the holes on our mounting plate here, it's gonna be 3 15/16, just shy of four inches center to center. So if you are needing to replace that original quick release mounting hardware, this is gonna be exactly what you need. That completes our look for today. Again, I'm Michael with, thanks for watching..

Replaces the mounting hardware for SportRack Horizon, Expedition, and Aero model cargo boxes, as well as Thule Excursion, Frontier, Mountaineer, or Traveler cargo boxes.


Original u bolts that came with the sportRack just didn't fit my oem vw crossbars. This product is exactly the same but with a little more space. Works well around the town and a road trip this summer will test it on a long trip.



Plenty of long road trips, works very well no complaints.


The product was exactly as described. Shipping was extremely fast, and the item was securely packaged eliminating any possibility of damage to the item during its transit. All steps throughout the entire purchase process went very smoothly, and customer service was superb! An all around pleasant purchasing experience!!!


Not the right parts, even asked for help
Was missing pieces/ didnt fit for what i needed but is a good temporary solution for my classic box from 1997


2015 Jeep Patriot Latitude
I bought
a used Sears X Cargo Carrier at a local thrift shop. It was in very good condition. But the latches were broke off and it had strap mounts only. The Replacement Latch for SportRack Explorer Cargo Box Item # 03347. Was an exact OEM replace match. X Sears Carriers were made by Thule. Install was simple and took about 5 min. The cross bar mounting kit was was again very easy to install. I have 52" CargoLoc cross bars. The length of the bolts left about 1.25" of threads. Hand tightening was all that was needed to lock the carrier firmly to the Jeep. I drove it out on the interstate at 70MPH. There was no handling issues with cross wind or at speed. The pics show the mounting hardware and the latches. Jeep owners this is an excellent system to expand cargo space.


Product worked just as desribed. I installed a late model Sears X-Cargo unit on our 2015 Chevy Traverse LT. The initial package arrived with a broken knob, but etrailer immediately shipped a replacement knob at no charge....a great way to stand behind their products and something I appreciate! I took a picture of the unit, but already removed after our trip. Thanks etrailer!


I think these are great parts


perfect fit, same as the original hardware that was on my Thule box. More importantly to me the folks at E Trailer made sure I had it in hand before a trip so I could use the box.


I was given a car roof carrier but the hardware needed was missing so lucky for me and that etrailer had the exact original replacement parts. Wish their shipping was as quick as that other online site but regardless the wait I’m very satisfied with this purchase at a fair price and highly recommend etrailer for all your needs when it comes to towing or other related needs for your car.


very excited to find these pieces!!! Sears does not sell them anymore and did not want to have to buy a new Cargo box . You saved the day.


Perfect fit for 2023 Subaru Outback!


Have owned a sears x cargo sport for over 20 years. Every 4-5 years I’ve replaced the hardware as most family trips are to the salt water air shore. Glad to find new hardware to keep my travels safe. Thanks


Needed this for a sears X-Cargo sport 20-SV….fit and worked perfectly


Perfect fit. The detailed product descriptions made it easy to buy the right replacement parts.


The hardware is sturdy and fit my old Thule Alpine box perfectly.


Product was fine, but if you have a plastic ski rack inside this largest size Thule Box, the bolts need to be a little longer to accommodate the rack base pieces, as they do not account for that. The rack was never that sturdy anyways and often fell over inside the box and we ended up just putting an old blanket down first and laying the skis and other stuff on that, which also absorbed any meltoff/water from the skis. So when I used this kit I just removed the rack base pieces and this kit worked fine. I feel much more confident without old rusty bolts holding this huge rack on the roof of the Suburban in case of a hard stop.

Unfortunately this product was unable to successfully mount a SportRack Vista XL onto my stock 2011 Nissan Xterra crossbars. The problem with the product is two fold, first the stock crossbars must mount a Vista Xl at their widest point which is where a thick plastic mounts it to the vertical bars making the distance between the pre drilled holes to far. Secondly even if you attempt to force it through there is not enough thread remaining to screw it on. Ultimately I had to drilled 4 sets of new holes approximately 4 inches towards the interior from the vista xl pre drilled hole. Using this substitute mounting set I was able to just barely screw it on to make it stay. I will definitely be going out to buy some longer bolts to ensure it won’t fly off mid drive.

Due to the very large diameter crossbars, mounting anything to the factory roof rack of the Nissan xTerra can be a challenge.


Very happy with this kit. Will be used on a Sears Xcargo Sport 20
Happy to have all the parts and some replacement parts as well.


This product worked great! I bought a used Thule and the plates were rusted. This was the perfect replacement.


Good quality materials. About the only thing I had to rig was rubber pads for the top and bottom clamps. Don't buy the mfr kit, this after market kit works fine. Thank you etrailer.



Still holding up fine.


Good on-line ordering experience, arrived within 7 days as expected, all pieces were in the package. Just what we needed. Hardware that came with the new larger SportRack that we ordered would not fit our cross bars, these work great.

Still working great. Thank you for asking.


I have an old school grey and white Sears x-cargo roof cargo box. These mounts worked perfectly. Even though they are not listed for this box, they still worked great. I traveled almost 3000 miles with them and didn't have any problems.



awesome, we have used the cargo box 6 times since we purchased the mounts and they are working out great. easy to attach and take off too.


This company has outstanding customer service. They kept up with the manufacturer on my order and I was kept informed and updated throughout the entire process. I was offered other options since my order was back ordered, but I chose to wait and I received both items just as I had ordered. Thank you to e-trailer you guys are great!!!!


Worked perfectly with my ancient Thule rooftop carrier, and my wife's Grand Caravan. Our road trips are taken with 3 kids , 2 dogs, and my wife and I. She tends to overpack, so having the carrier securely mounted to the factory bars is a huge help for managing the space in the vehicle.
Super easy to install, and the the quick mount/unmount are a blessing as well.
Simple but great. Thanks!


This product is an acceptable replacement for the archaic style originals your carrier may have had. These take forever to install because of the long threaded U Bolts.

I ordered this as backup along with an upgraded version that uses bolts that slide and lock in place with one twist. Unfortunately etrailer sold me the wrong upgrade kit because the U Bolts for it were not wide enough to match the holes in my Thule.


The hardware is fine enough and quality. Etrailer made it easy to get what I needed and I was able to put an older model Thule Evolution 1600 Large (Alley find) back in service. Thank you.
