Steeda Mustang IRS Subframe Alignment Kit (2015-2026)

Steeda Mustang IRS Subframe Alignment Kit (2015-2026)

Steeda's five in-house S550/S650 Mustangs all came with the rear subframe aligned properly from the factory, but a lot of customers weren't so lucky. The S550/S650's subframe mounting holes are very large compared to the subframe mounting bolts, and since there's a large difference in bolt and hole size, the subframe can be misaligned from the factory by up to 1/2" 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 and prevent corrosion, and it's lighter than aluminum or steel inserts. The Delrin sleeves slide into the subframe mounting holes and fill the extra space left between the subframe mount and bolt from the factory, guaranteeing the subframe bolts to the same location every time it is lowered and eliminating the need for unnecessary alignments.

Note: Customers running the BMR CB005 kit will need the Steeda Alignment Kit for BMR CB005 instead. An alignment is needed upon initial installation, since the subframe may have been misaligned from the factory and some adjustment may be needed once it's squared in the chassis. Also fits the S550 GT500.
