Steeda 2024 Ford Mustang Subframe Alignment and Support Kit
Steeda has come out with a kit that all S650 Mustang customers have been waiting for.. The Steeda Subframe Alignment and Bushing Support System!
We combined our ever-so-popular 555 4438 and 555 4437 kits into a money-saving combo kit where you, the customer, benefit! The S650’s subframe mounting holes are very large compared to the subframe mounting bolts. Since there is a large difference in bolt and hole size, the subframe can be misaligned from the factory up to 1/2″ from left to right. The Steeda Mustang IRS Subframe Alignment Kit is made from CNC-machined Delrin to avoid putting two dissimilar metals next to each other, preventing corrosion. Delrin is also less weight than aluminum or steel inserts, therefore keeping performance in mind. The Delrin sleeves slide into the subframe mounting holes and fill the extra space left between the subframe mount and bolt from the factory, eliminating any movement. Our Steeda Mustang IRS Subframe Alignment Kit guarantees that the subframe will be bolted to the same location every time it is lowered. Eliminating the need for unnecessary subframe alignments.
These Steeda S650 Mustang IRS Subframe Bushing Support System for your 2024+ Mustang GT or EcoBoost gives the rear end a much more solid feel with no NVH increase. The Steeda IRS Subframe bushings eliminate rear subframe movement notorious in the S650 Mustang GT or EcoBoost. A stiffened subframe allows the car to increase traction to the rear wheels and is the first step towards eliminating wheel hop. The Steeda Mustang IRS Subframe Bushing Support System for your 2024+ Mustang GT or EcoBoost is easy to install with basic hand tools. The Steeda IRS bushing kit also does not require any permanent modifications to the car.
