Steeda Mustang IRS Subframe Bushing Support System 2015-2024
These Steeda S550 Mustang IRS Subframe Bushing Support System for your 2015+ Mustang GT, Bullitt, Dark Horse & EcoBoost gives the rear end a much more solid feel with no increase in NVH at all. The Steeda IRS Sub frame bushings eliminate rear sub frame movement notorious in the 2015+ Mustang. A stiffened sub frame allows the car to increase traction to the rear wheels and is the first step towards eliminating wheel hop.
The Steeda S550 & S650 Mustang IRS Sub frame Bushing Support System for your 2015-2024 Mustang are easy to install, with basic hand tools. The Steeda IRS bushing kit also does not require any permanent modifications to the car.
