Steeda Mustang IRS Base Pack 2015+

Description

Steeda Mustang IRS Base Pack combines our ever-so-popular 555-4438 IRS Alignment Bushes and 555-4437 IRS Subframe Support Bushes kits into a money-saving combo kit where you, the customer, benefit! The S550’s subframe mounting holes are more significant than the subframe mounting bolts. Since there is a substantial difference in bolt and hole size, the subframe can be misaligned from the factory up to 1/2″ from left to right. The Steeda S550 Mustang IRS Subframe Alignment Kit is made from CNC-machined Delrin to avoid putting two dissimilar metals next to each other, preventing corrosion. Delrin also weighs less than aluminium or steel inserts, keeping performance in mind. The Delrin sleeves slide into the subframe mounting holes and fill the extra space left between the subframe mount and the factory’s bolt, eliminating movement.

Our Steeda S550 Mustang IRS Subframe Alignment Kit guarantees that the subframe will be bolted to the exact location whenever it is lowered, eliminating the need for unnecessary subframe alignments.

These Steeda S550 Mustang IRS Subframe Bushing Support System for your 2015+ Mustang GT, & EcoBoost give the rear end a much more solid feel with no NVH increase. The Steeda IRS Subframe bushings eliminate the rear subframe movement notorious in the 2015+ Mustang GT & 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 S550 Mustang IRS Subframe Bushing Support System for your 2015+ Mustang GT & EcoBoost are easy to install with basic hand tools. The Steeda IRS bushing kit also does not require any permanent modifications to the car.
