Using your Subaru OEM Fixed Roof Crossbar Set is easy. First, make sure your vehicle is a 2022 - 2025 Subaru WRX. Install the crossbars in just a few minutes by following the included instructions. You can use them with other Genuine Subaru roof attachments and carriers to increase your cargo - carrying capacity. But always keep in mind the total roof load weight limit of 88 lbs. Don't overload the crossbars. Since this is a clearance item with minor cosmetic flaws and one missing bumper cover, it's non - returnable. For maintenance, regularly check the hardware for tightness and clean the crossbars with a mild soap and water solution. Subaru of America will only warranty parts installed on a car with a matching VIN, so make sure to keep that in mind when getting your car serviced.
