These Ford Racing IRS knuckle sets are designed for use when custom-building your own independent rear suspension. They are manufactured from high-quality cast aluminum and include pre-installed bushings and steel roller bearings. The knuckle sets are built for the Ford Racing IRS Mustang Cobra hub assemblies, which are sold separately.
