Steeda Mustang Subframe Alignment and Support Kit (2015-2026)

Steeda has combined its ever-popular IRS Subframe Alignment Kit and IRS Subframe Bushing Support System into a single money-saving combo kit. The S550/S650's subframe mounting holes are large compared to the mounting bolts, which can leave the subframe misaligned from the factory by up to 1/2" left to right. The CNC-machined Delrin alignment sleeves slide into the subframe mounting holes and fill the extra space left between the subframe mount and bolt from the factory, eliminating movement and guaranteeing the subframe bolts to the same location every time it is lowered.

The IRS Subframe Bushing Support System gives the rear end a much more solid feel with no increase in NVH. It eliminates rear subframe movement notorious in the S550/S650 Mustang GT, EcoBoost, and V6, and a stiffened subframe increases traction to the rear wheels as the first step toward eliminating wheel hop. Both kits install easily with basic hand tools and require no permanent modifications to the car.
