Received on time and in good condition.



by:

You need 2 people to assemble this product in an efficient manner.
It is as advertised. A very good inexpensive carrier.



by:

Great product, easy to install. Best price we found anywhere,even with express shipping! Arrived quickly as scheduled. Perfect size for a small SUV.



by:

Nice & Fast Good Job-Well Done Thanks!



by:

Performed exactly as expected.



by:

Great 'price match' deal and fine, fast service. Got it the following day the price match was approved, when I was expecting it to be delivered in 2 or 3 days afterward. Thank you!



by:

More difficult to assemble than I expected. A bit frustrated but I made it.



by:

Expected it to be more rigid, the top is very flexible and needs to by wiggled around to seat correctly.



by:

Great people to deal with, product fit exactly as they said it would,
shipping was fast and at the door when they said it would be.
I definitely will order more stuff I need from these folks.



by:

Like many others, I found assembly to be...challenging. Something I found helpful was to attach the end supports first (the parts that prop the lid up when opened), BEFORE attaching the lid to the side hinges. The supports hold the lid up and allow some travel to better align holes for the hinges. Oh, I still had to get my legs inside the box for leverage and enlist the help of my 11 year-old son, but at least the lid didn't keep falling on my head while I did it!

Contrary to other reviews I've read all over the web, I did not find the lid or base to be flimsy. When assembled, the carrier felt fairly solid. Mounting is incredibly easy using the factory rails from Subaru.

Regarding size, I was pleasantly surprised by the amount of room in the interior, as well as the wide opening when loading. We're mounting this on top of our 2009 Subaru Outback and it is making a significant impact on the amount of stuff that usually winds up piled in the kids' laps during trips.

Overall a great product, a fantastic value, and the perfect solution to short or mid-range vacations. I would definitely recommend the Thule Sidekick to friends and might even offer to help with assembly...maybe.



by:

Thule website said this fit my 2014 Subaru Outback. Not quite.
I had to add two holes (one for each side) to get the rear clamp to work for the bar spread.
It does swallow a lot of gear, so thumbs up.
Also, got a little bit of water inside the box driving through a down pour in North Carolina.
Replaced a Yakima RocketBox that was just way too long for this car, and had similar issues on the road.
Quick shipment from etrailer.



by:

I received my product in an excellent, timely manner. This is the second time I have used etrailer and I would recommend them highly for future use.



by:

A good carrier and filled my needs. You definitely need two people to assemble it. Fits good on the car. Good valve for the money



by:

We used this product for a family vacation to South Carolina. It did the expected job.



by:

cargo carrierI really like my cargo carrier once it was assembled but attaching the top to the bottom half was quite difficult. Now that it's done I am very happy with it.



by:

Great unit for the price. I've taken thing on a few trips now with great success. It's traveled a couple thousand miles on top of my Subaru outback and has made vacationing much nicer. Then when we get home it's easy to take off and store



by:

Great car top carrier. A bit tricky to assemble. You definitely need someone to assist. Holds a good amount of stuff and fits on top of my Ford Escape nicely.



by:

Easy to assemble, good quality, too, but this is definitely designed for a sub-compact or just small type vehicle. I ordered thinking would be large enough for a 7 (seven) passenger van, and it wasn't large enough but for a few small pieces of our luggage. Just ignorance on my part. I will definetly order something else larger from your company. This was good quality for anyone.



by:

Received product on date as indicated. Was disappointed that product was not in inventory when ordered??? Assemble was easy. Hinge installation need definitely two people. Screws for hinges in package not the same as in guide sheet, thus little gray capes for outside don't fit!!!



by:

I once had an old Yakima Cargo Box (white on top & gray bottom) & I backed out of my car port w/its lid open~~of course, I totaled it! So, I chose the small Thule Cargo Box & was disappointed in its construction. 1). The box was very flexible due to its light construction. 2). The box comes w/two locks. Couldn't get the rear lock to catch because either the lock-arm was too short or the catch mechanism was riveted too low. Anyway my Yakima was of sturdy plastic which I had for a number or years. It held about 15 cubic feet of gear instead of the 8 that this product holds. I wouldn't recommend this product to any of my friends.



by:

Item was received as scheduled and exactly as described on line. I have purchased a number of items from etrailer and I am very satisfied with the products and service provided



by:

Best price I found on this item. Very fast shipping. The Thule Sidekick is a good box for the price. It seems a little flimsy at first but is sturdy when monted to my roof racks. Have taken it on a couple of test runs and it did great. Easy to put together with a helper. I have a 2011 Honda Element and it lines up perfectly with the factory roof racks. Great for the occasional user. Sure beats the almost $500 price tag on the Honda factory box.



by:

after owning thule cargo box for a year i have no complaints. It holds so much stuff that it really frees up lots of room in your vehicle for passengers or what ever else you have . Latches and locks work good,light weight & easy to switch from one vehicle to another. I also have a curt hitch on my crosstrek that i ordered from e-trailer. like your fast shipping and very helpful instructional videos. e-trailer is a great company.

  • Recommended Roof Cargo Boxes For 2005 Honda Pilot With Factory Roof Rack
    We have several cargo boxes that will work with the factory roof rack you have on your 2005 Pilot. The prices and sizes vary quite a lot, so you can decide which cargo box would work best for you. One of our least expensive boxes is the Thule Sidekick # TH78GC. This is an 8 cubic foot box that measures 54 inches long x 25 inches wide x 15-1/2 inches high, and weighs just 20-lbs. The next step up would be the Yakima Skybox 12, part # Y07334. This box has 12 cubic feet of storage and...

  • Is Replacement for Thule Dual Force Strut on Roof Cargo Box
    I reached out to my contact at Thule who said that part has been discontinued. Since there isn't a way to repair your current cargo box the only other solution is to purchase a different cargo box so you can keep your cargo dry and enough room in your vehicle for your application. If you like the Thule name and are in the market for a cost-effective option then I recommend the Sidekick # TH78GC. This is their economy option which uses the older style U-Bolts for mounting and it is smaller...

  • Recommended Roof Rack For A 2012 Toyota Camry To Carry A Roof Box
    We definitely have a roof rack for your 2012 Toyota Camry. I will also say that looking at Thule was a good option and is one of my preferences for this type of thing. So with that being said, the Fit Kit for Thule Evo Clamp Roof Rack Feet # TH145149 are specifically designed for your vehicle and will hook to the door jambs to secure the Evo Clamp Feet # TH710501 securely to the vehicle. From here you have two options. First will be the Thule SquareBar Evo Crossbars # TH712400. These are...

  • Does the Thule Sidekick Cargo Box Have to be Centered on the Cross Bars of a Roof Rack
    You can mount the Thule Sidekick to one side or the other when installing it on a roof rack cross bar. We recommend you put it closer to the passenger side so that if you were on the side of the road you would be on the side of your vehicle that would be on the opposite side of traffic.

  • Roof Box Compatible with 2019 Mazda CX-3 with Factory Installed Cross Bars
    While the SportRack Horizon Rooftop Cargo Box # SR7011 will fit the factory installed roof rack on your 2019 Mazda CX-3, it's just a little too long to allow you to fully open your rear hatch. For the hatch to fully open with the # SR7011 installed, there must be at least 52-1/2 inches measured from the center of the front crossbar to the line where the roof and hatch meet (see photo). If you can live with that, the roof box will otherwise fit nicely around your factory cross bars and will...

  • Roof Cargo Bag To Fit Factory Roof Rack On 2019 Infiniti QX60
    I do have an option for you but the Thule Interstate Rooftop Cargo Bag part # TH869 tie downs will most likely not reach the cross bar with that much overhang like you mention. I looked up your vehicle's factory roof rack and it doesn't look like it has raised rails either so it would be difficult to tie a bag that size down with a cross bar spread of 30". I recommend to use the Rightline Gear Sport 2 Rooftop Cargo Bag part # RL100S20 which will hook on the inside of the vehicle without...

  • Will the Thule Sidekick Cargo Box Fit on a 2007 Saturn Outlook
    If your 2007 Saturn Outlook has a factory roof rack with crossbars that run side to side, then the Thule Sidekick Cargo Box, # TH78GC, will fit. This cargo box requires a minimum crossbar spread of 23-5/8 inches. You can check your crossbar spread by measuring from the center of one crossbar to the center of the other. If you just have side rails that run front to back and no cross bars or your crossbars cannot be adjusted further than 23-5/8 inches apart, then you will need to add the...

  • Comparing the Benton ShellRaiser and Thule Sidekick Roof Boxes
    Hey Tommy, thanks for reaching out! The Benton ShellRaiser # B44FR and Thule Sidekick # TH78GC have the same interior space, but that's about all they have in common. The ShellRaiser is actually a better design due to it having dual-side access a wider crossbar spread compatibility, and an easier mounting hardware installation. The pricing of the Sidekick has more to do with the name behind it rather than a higher quality of materials or better features.

  • Will Thule Sidekick Fit Roof Rack Installed on 2009 Honda CR-V
    I did receive your picture and I confirmed with Thule that it is not a Thule roof rack that's been installed on your 2009 Honda CR-V. However, the Thule Sidekick # TH78GC may still work for you. To find out for sure you can measure the crossbars. As long as they are no more than 3-3/4 inches wide the Sidekick will fit. It's designed for aero shaped bars like you have. Another good measurement to take is from the center of the front crossbar back to the antenna. You'll need at least...

  • Can I Purchase the Thule Sidekick Mounting Screws, Screw Covers, Washers, and Nuts Individually?
    While we do have the mounting screws, screw covers, washers, and nuts for the Thule Sidekick Cargo Box # TH78GC, they only come in the kit # TH04958 that includes the rest of the hardware. I confirmed with the Thule schematics for the Sidekick that this hardware collection is the only hardware set available for the box.

  • How to Mount the Rhino-Rack Cargo Bag with a Thule Sidekick Cargo Box on a Roof Rack
    If you have the Thule Sidekick Cargo Box, part # TH78GC, mounted on your Honda CRV and want to add the Rhino-Rack Cargo Bag, part # RRLB200, there are two things you need to know. The first is that the Rhino-Rack Cargo Bag cannot be used on its own on a roof rack. In order to use it, you'll need a cargo basket. I recommend the Yakima SkinnyWarrior, part # Y07014. It fits factory bars and is our thinnest cargo basket. That leads me to the second thing you need to know. In order to mount...

  • Roof Rack Recommendation for 2016 BMW X3 and Cargo Box That Works With It and Other Vehicles
    Let's start with the roof rack, and for your husband's 2016 BMW X3 with flush mounted rails on his roof, I recommend the Rhino Rack Vortex Aero Crossbars # RRVA126B-2, which would mount to the roof with the Rhino Rack SRB Legs # RRSX026. As for that cargo box, you have a number of options depending on the cargo space you need, the spread of your crossbars, if you are looking for something aerodynamic, and of course, budget. The Thule Sidekick # TH78GC is the most economical option, though...

  • Can Thule Sidekick Roof Mounted Cargo Carrier Box be Mounted Offset on Roof Rack
    Yes, you can offset the Thule Sidekick Roof Mounted Cargo Carrier Box # TH78GC as opposed to mounting it directly in the center of the crossbars on your 2021 Kia Telluride. This opens up to the passenger side of the vehicle so I recommend mounting it closer to the passenger side of your vehicle so you aren't having to reach as far to gain access to the inside of the box.

  • Recommended Thule Roof Cargo Box to Fit 2014 Dodge Durango with OEM Crossbars
    According to Thule, the following cargo boxes will fit your roof if the center of front crossbar to rear hatch seam dimension is no greater than 51 inches.

Force XT Sport, part # TH6356B, internal length 68-7/8 inches, too short for skis Pulse L, part # TH615, maximum ski length 71 inches Pulse M, part # TH614, internal dimension 63 inches, probably too short for most skis Sidekick,...

    The Thule Sidekick Roof Mounted Cargo Carrier Box # TH78GC is compatible with roof racks that have a crossbar spread of 23-5/8" - 28". If your 2006 Subaru Impreza has the factory raised rails then you should be able to adjust the crossbars so that they are within this range so that you can use the Sidekick no problem. If your Impreza has the naked roof then it looks like the Inno square bar setup has a crossbar spread of 22.8" which is under the range for the Sidekick so you'll need to...

Low profile, aerodynamic design will minimize drag and road noise. Low profile will also be advantageous if you want to keep the box installed when you pull into your garage. For example, the Thule Motion XT 16 cubic foot # TH629506 measures 13-1/4" tall. According to the online owners manual for 2023 QX60, the vehicle should...

    The Thule Quick Grip Mount Assembly # TH05738 does fit the 2006 Jeep Commander with either the Sport crossbars or standard crossbars from the factory. However, to use them with the Evolution cargo box you would have to make modifications to the box. And you would need to use cradle # TH8523387001 for each foot. The feet and the cradles are sold in quantities of one. Making modifications to the cargo box can make it structurally unsound and not safe for use. I do not recommend making modifications...
