I was stubborn about getting to the bottom of the noise and tried moving the bar's locations around - test drive, whistle. Tried only the front bar - test drive, whistle. Only the rear - test drive, whistle. Covered the footings in microfiber cloths - test drive, whistle. Covered the Aerobars in microfiber cloth - the very thing/design that Thule markets as being the answer to quiet cross bars... surely the Aerobars were not the culprit... Test drive, silence.
Thule have done the hard work of figuring out how to best fit it to your car, though. You just dial in the angle between the arms, hang it on your car and tighten the straps. You can lock the ratchets, and there's a cable lock to secure the last bike in place so it's harder to steal rack and bike than is typical of boot racks. It folds tidily, but it's not light.
Thule Stacker Kayak Carrier Reviewed by Lisa J (Osceola, WI) — 2011-08-24 13:05:08 We were able to easily mount two sets of the Thule Stacker on the factory roof racks on our mini van, and easily carried our three kayaks that way. The tie down straps worked very well, and getting the kayaks on and off was easy. VIEW MORE REVIEWSShop Thule Stacker Kayak Carrier | Shop Thule
The lid has dual-layer construction, which adds stiffness for durability and ease-of-use while reducing drag for better MPG, as well as to lessen the noise. Spring-loaded hinges make accessing the box from either side of the vehicle a breeze, with lockable Smartlatch handles help make sure everything is shut up tight. Clamp mounts make the box compatible with most roof rack bar systems, though you’ll probably want to upgrade to one of Whispbar’s mounts to complete the look.
If you want a cheap and easy roof rack solution for short trips look no further than this affordable option from Highland. Although they're rated for a capacity of up to 400 pound, we'd recommend them for lighter items like ladders, kayaks, skis or snowboards. You may want to add a couple extra straps for a bit more security, but if your usual paddling spot or local hill are just a few miles away, this option do the job just fine.
I bought these Aero bars for my 2016 Jeep Wrangler Unlimited. Also purchased the Thule 300R gutter low feet. Make sure you link out to the Thule site to determine the right combinations of feet/bars to fit your vehicle when placing your order. The bars are good quality but installation instructions are a joke. They reference the foot pack for installation instructions. The foot pack tells you nothing beyond a vague illustration on how to install. Here is what I found out after several attempts and gouging out flesh on my left thumb:
If you already own parts or just want a complete set of used roof bars, then use the roof bar guide to find your vehicle, then at the bottom of the page, if we have used equipment available. you will be able to order separate items. Do note even though you have some parts always double check that you have the right length of bars and foot pack. To do this just look at the relevent package options, we list the items in that package that you will require for that vehicle.
Choose aerodynamic roof bars for superior performance and a sleek, sophisticated look that complements the lines of your car. These roof rack cross bars also have many smart design features. A textured surface disturbs the airflow and greatly reduces wind noise. The aluminium extrusion creates one of the strongest load bars in the market. The design gives you quick, no-hassle installation. While the end cap pivots and T-track make it easy to add further loading options.
