    Description

    Limit IRS Differential Movement. If you like to drive your GT Mustang aggressively on the street or at auto cross events you may find the factory Independent Rear Suspension is in need of a little extra help. It is know that the IRS differential of the 2015 to 2021 Mustang's is notorious for moving under acceleration, hard braking and even during spirited driving. This excessive movement can cause a laundry list of handling and traction problems, including differential deflection and wheel hop. However, by upgrading to a Steeda IRS Differential Urethane Bushing System you can considerably limit the movement of your S550 Mustang's IRS to improve traction and handling performance.

    Street and Performance. Steeda engineered their IRS Differential Urethane Bushing Insert System with Street and Performance drivers in mind. This Steeda IRS Bushing Kit includes two different options. The red 80 durometer bushings are for the Street use. While the black 90 durometer bushings are intended for Performance driving. As an added bonus these urethane bushings will not increase the NVH (noise, vibration, harshness) of your ride.

    Straight Forward Installation. The Steeda IRS Differential Bushing Insert System is designed to install with just basic hand tools in under an hour. No extra modifications or special tools are needed for a straight forward installation. Seeing that no permanent modifications are required you can switch between the two different durometer bushings as your driving needs change.

    Application. The Steeda IRS Differential Urethane Bushing Insert System is specifically designed for use on 2015 to 2021 GT Mustangs that are equipped with the factory Independent Rear Suspension (IRS). Not for use on V6 or EcoBoost models.
