      Description

      Stay Safe. Have you been in an accident or experiencing excessive wiggle or play in your rear wheels? Then you may need to replace those worn out Rear IRS Knuckles and Wheel Hub Assemblies with a brand new set from Ford Racing. Bad knuckles and bearings are not something to be ignored, they should be replaced ASAP  to avoid a possible accident.

      IRS Knuckles. The included Ford Racing IRS Knuckles are manufactured to the original factory specifications from cast aluminum for superior strength and light weight. The Knuckles come with the bushings and steel roller bearings pre-installed for ease of installation.

      Genuine Ford Part. These genuine Ford Wheel Hub Assemblies are manufactured to the original factory specifications from OEM quality materials. The assemblies come complete with the bearings and studs already pressed into the hub for easier installation.

      Application. This Ford Racing IRS Knuckle and Hub Kit is designed to be a direct fit replacement for all 2015 to 2025 S550 Mustangs, including the V6, EcoBoost, GT and Shelby models.
