The team at Steeda went hard to work when we started fielding calls of the rear sub-frame being misaligned from the factory. So here you have it, Steeda’s new S550 IRS sub-frame alignment kit!
The S550’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 mis-aligned from the factory up to 1/2″ left to right.
The Steeda S550 Mustang IRS Sub-frame 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 then aluminium or steel inserts and therefore keeping performance in mind. The Delrin sleeves slide into the sub-frame mounting holes, and fill the extra space left between the subframe mount and bolt from the factory.
Our Steeda S550 Mustang IRS Sub-frame Alignment Kit guarantees that the sub-frame will be bolted to the same location every time it is lowered. Eliminating the need for unnecessary alignments.
