The complete Thule 400XT Aero roof rack system is the multi-purpose base rack solution for cars and truck cabs without rain gutters or factory racks (a naked rooftop). The new Thule 400XT upgrades make it easier than ever to install. We highly recommend a four pack of Thule Locks (not included; see accessory add-ons below) to lock the rack to vehicle.
The Thule 400XT Aero complete roof rack system includes all 3 components that are necessary for installing a general-purpose base rack on your vehicle's roof top, providing the platform that will allow you to then connect roof mount gear carriers that carry your gear and equipment:
- Four (4) Thule 400XT Aero Feet.
- Four (4) Thule Fit Kit clips (specific to your vehicle; see ordering notes below).
- Two (2) Thule Load bars (bar end caps included).
Protective surfaces on rack prevent shifting and protect car's paint. No tools required for assembly; easy-to-follow installation instructions manual included. Can be locked to the rooftop using a 4-pack of Thule Racks One Key System lock cylinders (not included; see accessory add-ons below). Thule Racks Lifetime Warranty!
NOTE: Short roof lined cars including 2-door models must check the Thule Racks automated fit guide (see right or below) to find out if your car or pickup truck requires the additional Thule 477 Short Roof line Adaptor component (sold separately; see accessory add-ons below).

DONT TIE YOUR FRIENDS TO THE ROOF-even though it is safe and durable enough to transport your toys!
this Thule 400XT Review by Paige Moyer
vehicle year/make/model: 1996 Honda Civic
item(s) transported: Snowboards, and skis. Also random cargo like camping gear
I have never owned a vehicle with a factory rack, but I imagine that this Thule car rack is just as effective! I love the extra space in my car and I am not concerned about damage to the outside. This rack is great because it is removable and easy to install. I did it myself! It seems very safe and it is very affordable.
What I was Expecting, Installation was Average
this Thule 400XT Review by "E"
vehicle year/make/model: 2002 Volkswagen Golf
item(s) transported: Roof Box
The rack is definitely secure which was my #1 concern. Installation was a bit confusing, but it was completed within 30 minutes. Luckily, I haven't experienced much noise without a fairing and I do not plan on buying one. I put a piece of cloth between the feet and the roof of my car to prevent any marks and it seemed to work.
Good but you need to buy a fairing
this Thule 400XT Review by Oleg
vehicle year/make/model: 2003 Dodge Durango
item(s) transported: Cargo Box
This rack is pretty good. It is durable and strong. Only one issue I have is that it is noisy at higher speeds. But I bought a fairing and it went away. Just wish I didn’t have to buy the fairing. Rack was expensive enough.
Hard to install but solid and secure once installed
this Thule 400XT Review by GS
vehicle year/make/model: 2006 Saturn Relay
item(s) transported: Canoe, kayak, skis
I just installed the Thule 400XT rack and it took me about 2 and a half hours to install. I found them very
difficult to work with, but I guess the thing that matters is how secure they are once they are installed. As far as that is concerned, they are very good, very secure feeling. Don’t think they are going anywhere anytime soon. The fit kit fits perfectly in my door frame and doesn’t interfere with the door or the gasket. I was worried that they would cause the car to leak in the rain, but they don’t. Again, a total pain to install, but very solid construction and secure once on there. I might suggest paying to have an expert install them for you.
Make Sure you have the Right Fit Kit
this Thule 400XT Review by Toby T.
vehicle year/make/model: 2007 Volvo S40
item(s) transported: Bikes in the summer, skis in the winter, random stuff year round
I've been using Thule racks for years. They are pretty easy to install once you have the right fit kit! Make sure you have the right fit kit! I thought I could use the same Fit Kit from my older S40. Wrong! I recommend a fairing unless you enjoy high pitched whistling. Also, make sure you wipe the feet and the roof before you install. When I took the racks off the old car there were scuff marks left behind.
Product Discussion

wiltie asks - I notice that your roof racks are mostly for sports equipment, bikes, kayaks, etc. We have a 2006 Honda Civic. Do you have any racks strong enough to support heavier loads, like 2x4's, sheet of plywood or other heavier type loads.
ORS Racks Direct crew answers - Our manufacturers' roofrack systems are actually a great choice for carrying commercial / construction materials as well. These racks are much stronger than factory racks. The Thule 400XT Aero car rack system fits your 2006 Honda Civic superbly and includes a set of Thule 2171 Fit Kit clips and pair of LB58 58" length load bars. You can then attach the Thule 503 Load Stops to the load bars. The general purpose Thule 503 Load Stops are an excellent carrier for ladders, lumber, plywood and much more.
