I have been really happy with this roof box, I was concerned at first because it did not feel as heavy or sturdy as some I've had in the past but it's performed really well and the shape is great. Because of the shape it holds things like carry on luggage on their side, backpacks and lots of gear. A year in, still loving this purchase.



by:

Worked great on my 2022 Prius. Had to drill holes to make clamps fit the factory roof rack.



by:

This review is not about the Thule Sidekick I ordered. It is about etrailer. Their prices are very competitive and I received free shipping. I placed my order on a Friday, was promised delivery the following Thursday and my item was delivered two days earlier on Tuesday. I will certainly consider etrailer for future purchases.

No complaints, the Sidekick is a lower end cargo carrier but that is reflected in the price and it suits my needs just fine.



by:

This cargo carrier is perfect for our needs. Stacey with etrailer helped with ordering & any questions we had. The topper arrived quickly, we didn’t install immediately waiting on roof rack rails.
A week or so later ready to install we noticed a rivet missing on the front lock… took pictures & emailed Stacey. She called back within hours & the next day a replacement was on the way…..

We’d give 10 stars for her exceptional Customer Service! Thank you for exceeding our expectations!



by:

The sidekick has been a great cargo box for road trips over the last year.

Quick delivery. We just put together the box, haven't used it yet, but everything looks good.

Works great. Weve used it a half a dozen times, and it has worked well each time.



by:

I have a 2016 ford focus se hatchback & I mounted this in the middle on rhino rack vortex bars. Looks awesome! It’s very sturdy & I can fit a decent amount in this box.



by:

This is a great addition to my Subaru Forester for camping and outdoor adventures! It holds up really well even during a rainstorm. Very happy to have purchased it.



by:

We've used a few times for long trips with 5 kids and 2 adults. It definitely gave us the cargo space we needed for the trip.



by:

Got Very Frustrated on step one as Paper kept sticking to foam sealer, until I cut back nearly 12" of material!
Directions are MINIMALLY Clear. Luckily I am an Engineer and got lucky via deductive reasoning



by:

It works great. Easy enough to put together and install/remove from the car. We were torn between this and slightly bigger model. Could have went bigger, but this freed a lot of space and made packing Tetris much easier.



by:

This was a game changer! We have started making trips from TX to NC and NC to FL several times a year. After getting 2 adults, 2 teens and 2 dogs in my Lexus NX, there's not much room inside the car for much. Getting this Thule roof rack box has been great. Amazing how much stuff and then some will fit. Minimal noise and insignificant impact on mpg too. Great purchase.



by:

Meets its needs. Plastic is rather thin - definitely meant to haul lighter items, but is rather spacious for its compact length. Requires some assembly with two people. Spouse is happy because it fits some extra beach gear she wanted to haul on vacation.



by:

It’s been great overall, but the key did break in one of the locks which has been inconvenient.



by:

Like the product, good quality, easy as sembly



by:

Thank you for shipping so quick. I received it in 2 days.



by:

product arrived on time and in excellent condition.



by:

Delivered Thule rooftop box on time in excellent condition.



by:

It arrived a bit banged up. There were a number of dents probably related to being banked around during shipping. Most popped out. One or two may not. I haven’t put it together, so maybe they’ll relieve. We’ll see

Wow! I am sorry you had a bad experience with the cargo box. Thule is one of our most trusted brands so forgive me if I sound surprised. Can you give me more information about why the box is crappy? I am happy to help!



by:

From purchase to delivery, etrailer was amazing. Thanks for making everything easy.

Was a great fit for the Tacoma SX model.

Looks nice

One of the hinges were broken when I received the item

Perfect! Just what we were hoping for.

  • Rooftop Cargo Box or Cargo Basket for 2017 Honda CR-V With Factory Roof Rack
    The best cargo box is definitely going to be a Thule, and there are a number that I have confirmed will fit the factory crossbars of your 2017 Honda CR-V. The biggest issue is going to be antennae interference because even the shortest rooftop cargo box that fits, the Thule Sidekick Roof Mounted Cargo Carrier Box # TH78GC, is 54 inches long and may interfere with your antenna. The Sidekick cargo box would be your best option in regards to fit, with the 67 inch long Thule Pulse Medium Rooftop...

    We can definitely help you explore various cargo solutions for your trip. I was not able to find an online copy of the owners manual for the 2002 Grand Vitara but I was able to confirm the towing capacity - 1500 lbs. You will want to confirm the combined weight of your specific boat and trailer to ensure it is within the 1500 lb limit. Please note that there are no front-mount hitch receivers available for your Grand Vitara, so carrying your motorcycle on the front of the vehicle is not...

  • Using Thule Rack System and Stacker # TH830 to Equip 2010 Corolla for Carrying Two 10 Foot Kayaks
    Thule offers a good solution for carrying your kayaks on the roof of your Corolla. You will want to begin by checking your owners manual for the roof capacity of your vehicle, and make sure you do not exceed it. You would first need to attach a roof rack system to the roof of your Corolla. By combining Thule SquareBars, part # TH712200, The Thule Rapid Traverse Foot Pack, # TH480R and the vehicle-specific fit kit, # THKIT1515 you would have a great rack system to carry your kayaks.

  • Roof Cargo Box Recommendation that Fits 2015 Toyota 4Runner
    I did some checking and was able to find a roof cargo box that does fit the roof rack you have on your 2015 Toyota 4Runner but the Inno part # INBRA1150BK you mentioned does not due to the clamps being too thick. The only solution we have is the Thule Sidekick part # TH78GC which uses U-bolts instead that are much narrower. This fits the very limited clearance your roof rack has.

  • Roof Rack For 2010 Subaru Outback For Use With Thule Cargo Box
    Assuming your 2010 Subaru Outback has raised side rails, there is a roof rack that is simple to use that will fit and allow you to carry a rooftop cargo box, including boxes from Thule. The rack I recommend is from Malone: - Malone AirFlow2 Roof Rack # MPG216 The AirFlow2 Roof Rack # MPG216 is an excellent value for a roof rack that has long, 58" crossbars which also measure 3" wide and 1" tall. With this rack you will be able to mount Thule rooftop cargo boxes such as the Thule 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...

  • Fitmment of Thule SideKick # TH78GC on a 2021 Hyundai Venue with Moonroof
    Yes! The Thule Sidekick # TH78GC definitely fits your 2021 Hyundai Venue. In order to mount the box to your roof, you need a roof rack system with compatible crossbars. The parts you need depend on if you have a bare roof or raised factory rails. If you have a bare roof, I recommend the following setup: - Yakima JetStream Crossbars - 50" # Y00425 - Yakima BaseLine towers # Y28TR - BaseClip Fit Kit # Y06170 - BaseClip Fit Kit # Y06187 - Same Key Lock Cores # Y07204 If you happen to...

    The only cargo box that has been verified to fit your 2015 Toyota 4Runner Limited OEM roof rack is the Thule Sidekick # TH78GC. All of the other options basically say there isn't enough room for the mounting hardware. If you want/need to use something larger then we need to get you an aftermarket roof rack system. If you'd like to upgrade your crossbar system just let me know and I'll be happy to make some recommendations for you, otherwise have fun with the Sidekick! I've attached a review...

  • Will the Thule Sidekick Cargo Box Fit a 2015 Subaru Outback without Hatch Interference
    For the Thule Sidekick Roof Mounted Cargo Carrier Box - U-Bolt Mounts - 8 Cubic Feet Item # TH78GC there will need to be at least 51-7/8 inches from the center of the front crossbar to the line where the roof and hatch meet to avoid hatch interference on your 2015 Subaru Outback. I do have another option for you though. You can use the Trunx Rooftop Cargo Box - 18 cu ft - Black # TRX34FR which requires just 36 inches clearance. Plus it costs less and has more cargo space than the Sidekick!...

  • Will the Thule Sidekick Fit on My 2008 Chrysler Pacifica with Factory Roof Rack
    I spoke to my contact at Thule and, the TH78GC Sidekick will most likely mount to your factory roof rack as long as you have two cross bars and they will adjust for the following measurements that are required for mounting the cargo box. The Sidekick needs 23-5/8 inch minimum spacing and 28 inch maximum spacing of cross bars front to back on your vehicle. The sidekick also requires 14-3/8 inch mounting width and 7-1/2 inches of rear clearance. There are four fixed holes for mounting u-bolts...

  • Does the Thule Sidekick Have Hinges, Locks, and a Seal
    The Thule Sidekick Roof Mounted Cargo Carrier Box # TH78GC does use a combination of hinges and struts to easily raise and lower the lid. It includes locks to deter theft of your gear and although there isn't a "seal", there is a foam gasket included to help keep your gear safe from the elements.

  • Roof Top Cargo Box Fit for 2012 Volvo S60 with 29-1/2 Inch Crossbar Spread
    I have a solution for you, but the Thule Sidekick Roof Mounted Cargo Carrier Box # TH78GC will not fit the roof rack on your 2012 Volvo S60, unless one of the bars can be repositioned. This cargo box will mount to crossbars that have spreads between 23-5/8 inches and 28 inches. Since your crossbar spread is 29-1/2 inches, the bars would be too far apart to mount the Sidekick. For a cargo box similar in size to the Sidekick, you can use the Inno Ridge Rooftop Cargo Box # INBRA220R-BK....

  • 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...

  • Can Roof Mounted Cargo Box be Mounted Vertically on Van Rear Ladder
    I may have an option for you, however none of the roof mounted cargo boxes we have available are designed to be mounted vertically. The mounting hardware and box design will not be secure enough for this mounting orientation when driving down the road. Since I see there is a trailer hitch installed on your ProMaster, I instead recommend looking at a hitch-mounted cargo carrier. For a carrier that features larger cargo space similar to a roof-mounted unit, the Yakima EXO Swing Away Enclosed...

  • Can I Carry A Small Rooftop Cargo Box On Factory Roof Rack With Crossbar Spread Of 32"
    I do have a solution for you, but it will not be a Thule Sidekick. The Sidekick will fit on a vehicle that has a crossbar spread of 23-5/8" to 28", which is shorter than the 32" the factory rack on your 2021 RAV4 provides. Since your crossbar spread is fixed at 32", you will be limited to roof top cargo boxes that are at least medium in size. The small and extra small offerings will not work with crossbar spreads of 32". I recommend the SportRack Horizon Rooftop Cargo Box - 16 cu ft - Black,...

  • Recommended Roof Rack for 2019 Honda Civic
    We do have a really nice selection of roof racks that will work great on your 2019 Honda Civic. I highly recommend the Yakima JetStream Roof Rack which consists of # Y00425 for the two 50 inch JetStream Crossbars, # Y28TR for the BaseLine Towers, # Y06182 for the Front Fit Kit, and # Y06183 for the Rear Fit Kit. This will provide you with an extremely aerodynamic roof rack with built-in windridges on the bars that help to control air flow and dramatically reduce wind noise and vibration....

  • Will the Yakima RocketBox 12 on the Vortex Aero Crossbars on the # Y02-490B for a 2005 Dodge Dakota?
    I went ahead and reached out to my contact at Yakima, and she said that while they cannot confirm that the Yakima RocketBox Pro 12 Y07191 can clamp around the Vortex Aero bars on the # Y02-490B on your 2005 Dodge Dakota, she said they should work. If you want something that will definitely clamp around the bars, I recommend theThule Sidekick Roof Mounted Cargo Carrier Box - 8 cu Feet # TH78GC or the larger SportRack Vista XL Cargo Box - 18 cu Feet # SR7018. Both of these roof boxes come...

  • Lock Cores For Thule Evolution Cargo Box
    There are replacement lock cores and keys for your Thule Evolution cargo box, and if that's what you were referring to by "locking system" then you can replace them with Thule One-Key System Lock Cylinders # TH450200. Otherwise, if your cargo box won't work due to not having a locking system then there is no other alternative, you will need a new cargo box, like the Trunx Rooftop Cargo Carrier # TRX44FR or Thule Sidekick Roof Mounted Cargo Carrier Box # TH78GC.

  • Cargo Boxes for 2013 Lexus RX350 That Wont Interfere With Rear Hatch
    You'll need to take a measurement to determine which rack would be best. If your front roof crossbar is adjustable, move it all the way forward. Then, measure rearward until you reach the seam between the rear hatch and the roof. Consult the last column of the table I provided, and compare your measurement to those shown. If your vehicle measures less than the number listed, that cargo box will fit your vehicle without contacting your hatch. For example, if your measurement was less...

    The SportRack SkyLine XL Cargo Box SR7095 that you referenced will require you have a roof rack with crossbars installed. However, it would not be compatible with the crossbar spreads that are available on the roof racks that are confirmed to fit your vehicle. You would need to use a different box. First, let's start with a roof rack. For that I think you would like the SportRack Semi-Custom Roof Rack part # SR1002. For a similar cargo box that would fit this rack I would recommend the...

  • Cargo Bag or Box For Golf Clubs On 2010 Toyota Highlander
    The standard golf club length is 45-1/2" long from my research. I recommend Rightline Gear Sport 3 Rooftop Cargo Bag part # RL100S30 which measures 48" long x 40" wide x 19" tall which is plenty enough space for a bag of golf clubs. This bag attaches to a roof rack, cargo basket or bare roof. The integrated tie down straps will keep the bag snug on the roof so the golf clubs are not sliding around up there. I personally think the best way to carry golf clubs is in a a cargo box on the...

    According to Thule, there is a necessary crossbar spread as well as the clearance needed from the front crossbar to the rear hatch seam. This is what they can absolutely confirm will fit. Because your front clearance on your 2015 Mazda CX-5 is 45 inches, they can't confirm that the Thule Force XT Rooftop Cargo Box - 16 cu ft - AeroSkin Black # TH6357B will fit and allow you to open your hatch completely. This carrier has a front clearance of 47-1/2 inches as you mentioned so that would...
