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.

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.

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.


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!!!!


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.


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.


The hardware fits as stated for a Sears SportsRack 20. I’ll be giving it a performance run within the week as I’m traveling 400 miles with the cargo carrier. If anything goes wrong, I’ll update my review.


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!


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


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.

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.

website easy to follow, always have inventory in stock at a reasonable price, great service. Thanks!


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.

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.

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!


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 bought this kit to mix and match with another one. The original equipment I had on my Thule Frontier cargo box was all plastic. I wanted the metal plates to replace the plastic ones outside the box. This kit doesn't have the rubber gaskets it should to protect the bars and keep it from sliding. I ended up using the TH04997 kit which replaced the plastic parts outside with metal ones and came with the gaskets. I'll keep this one for spare parts.


I ordered this kit as a replacement for the stock brackets that came with an old used Thule cargo box. The original brackets that came with it, would not fit the wide aerobars on my minivan. This mounting kit, fits the bars as well as the box perfectly! Ordering was easy and the shipment was delivered very quickly.

I could not be happier with this $xx kit for an old box!


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.


Excellent and informative catalog/website. I found all the information and the parts I needed quickly at competitive pricing. I ordered the cargo carrier mounting kit and shipping was very fast. The parts were high quality, original equipment parts. It was nice to save money without sacrificing safety or convenience. And it's a plus for the environment when you can extend the useful life of a product.


Product is worked exactly as expected. I have had the roof box installed on my car for a year now and other than ensuring that the bolts are tight every few months there have been no issues.

On customer service, I originally received the product with a hole in the bag and a few missing parts. After contacting a sales agent a new set of parts was sent out with no questions asked.

Will use etrailer again and would recommend.


very good. Completely satisfied.

have a x-cargo luggage carrier,
model 28-7271 (18 cu ft)
The rear hold down bracket has broken. Need a replacement.


Good product. It solved the problem of adapting an old cargo box to new wider load bars on my subaru outback. Bonus: it's easier to mount the box now than it was with the original hardware.


My old Thule Adventure just won't quit, but the hardware was tired. etrailer had the kit I needed in stock and shipped immediately. Easy fast ordering and delivery. Now I just need to swap out the components and put it on the car for our vacation.


Although, this is not the hardware number that was listed for my Sears Sport 20 SV Cargo Carrier (it was TH04851 that looks to be sold out); it is exactly the same kit and fits perfect. Seems that SportRack and Thule=Sears carry the same hardware manufacturer in this case.


Product was exactly as advertised. I cannot say for sure if this hardware replacement kit is OEM but the quality is excellent and everything fit perfectly. Shipping was very fast. I will gladly use again!
