Steeda IRS Differential Bushing Insert System; Urethane (15-21 EcoBoost)

Limit IRS Differential Movement. If you're like many other EcoBoost drivers you know your Mustang's Independent Rear Suspension is in need of a helping hand. It is well know that 2015-2021 Mustang's IRS differential likes to move under rapid acceleration, hard braking and during spirited driving. This movement can cause a whole host of handling and traction issues, including differential deflection and wheel hop. However, by upgrading to a Steeda IRS Differential Urethane Bushing System you can greatly limit the movement of your 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 EcoBoost Mustangs that are equipped with the factory Independent Rear Suspension (IRS). Not for use on V6 or GT models.
