Thule Top Track Roof Mount System, 42" Long - THTP42

Average Customer Rating:  4.5 out of 5 stars   (6 Customer Reviews)

Thule Top Track system permanently mounts to the roof of almost any SUV, Minivan or camper.


I’ve been wanting to add an old set of crossbars to my camper for a while, but had no way to attach them. These top tracks were the perfect solution. I can now use a rack, bike/kayak mounts, anything and take advantage of the added storage capacity. To keep the curvature, I trimmed mine down a few inches with a mitre box and hacksaw.

No issues, and they work great!


They answered my questions regarding install very quickly, with attached printable documents. Also, thought some parts were missing, once again quick response and suggested I look more thoroughly in the box, and they were right! I will buy all my trailer and rack needs from them in the future.


Nice and prompt! The item was just as said.
Fast shipping!!


Arrived on time. Can’t wait to mount on my truck

  • Where Does Thule Track THTP42 Install on 2014 Honda Odyssey
    I spoke with my contact at Thule about the install of the # THTP42 on your 2014 Honda Odyssey and this is what they told me: 1. They should have a body shop install the tracks. 2. The body shop can get the information from Honda as far as where (and where not) to drill). Thule does not have that info because automobile manufacturers don’t like to share it with us but they will tell the body shops.

  • Will Thule Top Tracks Fit a 2013 Nissan Frontier Crew Cab
    Technically you could install the Thule tracks # THTP42 on any viable surface including the roof of your 2013 Nissan Frontier. But I am not sure why you would want to drill holes in the roof of the vehicle. If you want to go forward with that then the only way I can think of to get a diagram of roof supports or other things in the roof is to ask Nissan directly. I have included a link to the roof rack we have for your truck that do not require drilling holes in the roof.

  • Can a Thule Tracker System Be Installed on a 2012 Honda Pilot
    I do have options for you but they do not make a roof track system specifically for your 2012 Honda Pilot. In order to mount a set of tracks like the Thule Top Track Roof Mount System part # THTP42 on your Pilot you would need to either bolt or rivet the tracks onto the vehicle. There are no pre drilled holes on your Pilot to accept the tracks so drilling will be required. I recommend placing the tracks inside of the ditch as this will make fitment much easier.

  • Could Rivets be Used to Install Thule Top Track Roof Mount System # THTP42

  • What Tools Are Needed to Install Thule Top Track Roof Mount System
    Yes, the installation instructions just have you installing the Thule Top Track Roof Mount System # THTP42 from the roof of the vehicle and not having to do anything on the inside. You will drill the holes in your roof using a 1/8" drill bit and then installing the M5 flare nut insert (see linked instructions). The 1/8" drill bit is included with the kit so the tools you need to have handy on your end (which are pretty common) include the following: Masking tape 9/16" Wrench Center punch Hammer Tape...

  • Do Thule Tracks Fit in Ditch of 2017 GMC Canyon

  • Can The Thule Top Track Roof Mount System Be Installed On A Bare Roof Of A 2019 Chevrolet Equinox?
    Yes you can absolutely install the Thule Top Track Roof Mount System # THTP42 with your 2018 Chevrolet Equinox. This system can also be installed on your own, the parts are very light weighing only 3-lbs for the pair so you shouldn't have any issues with that, however it's also never a bad idea to have a buddy get a second set of eyes on it. To install it you're just going to need to align the tracks to each other and position the ends equally apart from the reference line on your vehicle,...

  • Could Thule Roof Rack Track Be Installed on 2017 GMC Sierra
    I don't like recommend track style roof racks on brand new vehicles as they require drilling through the roof and head liner. If you absolutely wanted to you could install the part # THTB60 I am sure you could. A better option may be the 42 inch long version though part # THTP42 since you want it shorter. Or the 54 inch part # THTP54.

  • Can I Put Roof Rack Tracks On My 2017 Honda CR-V
    Yes, we do sell roof rack tracks that can be drilled into the roofs of vehicles. The Thule Top Track Roof Mount System, 42" Long, part # THTP42, is an example of one of our Thule options, but we also sell Yakima and Rhino-Rack tracks. Each of these vendors also sells the kits to attach their roof racks to tracks as well. I recommend that you speak to a body shop to verify that you can install the tracks on your vehicle. I do not think you will have any issues with regard to their installation,...

  • Are the Thule and Rhino Rack Square Bars the Same Dimension
    Rhino Rack square bars like the # RREB126B are 1-3/16 inches wide and 13/16 inches tall. Thule square bars like the part # TH712400 are 1-1/4 inches wide and 7/8 inches tall. So while they are very close to the same size they are different.

  • Fit of a Roof Mounted Top Rack System on a 2013 Ram 3500
    We don't always list fit information for track kits because of the varying applications of them on trailers, camper shells and actual vehicles. This is because of the numerous variations of these vehicles and the fits that would need to be listed out for each individual vehicle. In this case, your 2013 Ram 3500 would be able to have the Thule Roof Mounted Top Rack, part # THTP54 installed on the cab's roof by drilling into the vehicle. However, the vehicle is also capable of having clamp...

  • Roof Rack for a 4300 International Ambulance
    For your application I recommend going with the Thule track mount system as that has the longest bars at 79" which will fit with a current foot pack. You will need tracks and a whole roof rack package. I will have these separated out so that you can choose the best track length for your application. Please keep in mind that the weight capacity of the roof is typically the limiting factor when it comes to load capacity so you'll want to see if you can find out what that is for your 4300...

  • Can I Use Yakima SkyLine Towers with Thule Tracks?
    Yes, the tracks themselves recreate the factory C-shaped rack tracks. Thule Tracks # THTP42 and Yakima Tracks # Y01126 have the same C-channel design, but differ in length and how they mount to the vehicle. To use your SkyLine Towers # Y00148 with these tracks, you need the Yakima Landing Pad 1 # Y00221. This is the mount that fits directly into track systems and can be used with SkyLine or Control Towers.

  • Recommended Roof Rack for 2017 Honda Odyssey with Naked Roof

  • Roof Cargo Basket and Roof Rack Recommendation for Chevrolet K5 Blazer
    I have a solution for you, but there is no type of cargo basket that is available to mount to a flat roof without bars. The Safari cargo baskets are designed to fit to roof racks or raised side rails. Since you have no rails or bars on your vehicle, to be able to use a cargo basket you will need to install a roof rack. A track mounted roof rack will allow you to install the rack on the back, hard cover of the Blazer. For a track, I recommend the Thule Top Track Roof Mount System, 42...

  • What is the Total Height of the Rhino-Rack Roof Rack for Thule and Yakima Tracks?
    The total height from the bottom of the legs to the top of the crossbars on the Rhino-Rack Roof Rack for Thule and Yakima Tracks # Y01-120B-NT is 4-7/8 inches. If you account for the length of the height of the Yakima Tracks # Y01127, it adds about a 1/2 inch to the total setup. With the added track length of the Yakima tracks, you are looking at a total height of 5-3/8 inches on top of your 2020 Toyota Tacoma. The Thule Tracks # THTP42 will add about an inch to your total setup, which...

    The Replacement M8 T-Bolt # 853-5715 you were looking at will fit Thule crossbars or the Thule TracRac and Xsporter Ladder Racks but will not work in your Thule Top Tracks. The Thule Top Tracks like the # THTP42 are not designed for T-bolts and instead is designed for the Thule Rapid Podium Feet # TH460R with fit kit # THKIT3101, and then allow you to install the Thule AeroBlade, WingBar Evo, SquareBar, or ProBar load bars of your choice.

  • Will any of the Thule T-Bolts Fit Thule Tracks?

However, Thule does make T-bolts that are designed to fit Thule AeroBlade, AeroBlade Edge, or WingBar Evo crossbars. The T-bolt kit that fits these models of crossbars is the Thule Xadapt12 Watersports Adapter for AeroBlade, AeroBlade Edge or WingBar Evo Crossbars # THXADAPT12. With that being said, the T-bolt hardware in the Xadapt12 is only designed...
