Differences Between Thule 400 Aero Foot and 400XT Aero Foot

Thule is a leading manufacturer of vehicle roof racks designed for transporting sports and outdoor recreational gear. Thule's roof racks are comprised of three separate components: load bars, base "feet" that hold the load bars in place on the roof and vehicle-specific fit kits for correct mounting. The 400 Aero Foot was a popular product used as part of Thule's aftermarket roof rack system until it was revamped and released as the 400XT Aero Foot.

  1. Differences

    • Several improvements make the 400XT Aero Foot stand out from its discontinued predecessor. Each 400XT Aero Foot has a plastic cover that helps it blend with the vehicle's roof profile and reduces noise, a fully-threaded handled bolt that makes it easier to secure to the vehicle and a lockable hood to prevent the racks from being stolen.

    Cost

    • Thule sells a package of four 400XT Aero Foot supports for $174.95, at 2011 prices, directly from their website. Many online retailers also offer competitive prices. In addition, the 400XT Aero Foot package can be purchased directly from car dealerships and kayak, bike and other outdoor specialty stores.

    Compatability

    • Although the Thule website indicates that all fit kits are compatible with all versions of the Aero Foot, a proper fit to your car is essential. Since Thule produces a variety of products to accommodate a wide array of vehicles, some buyers may prefer purchasing Thule equipment like the 400XT Aero Foot from a local car dealer or sporting goods shop that is familiar with Thule products and can order the correct items and provide installation services.
