    UPR IRS Subframe Alignment Kit for 2015-2019 Ford Mustang S550s. CNC machined from Delrin to help align the factory IRS subframe, which is known to come mis-aligned from the factory. The factory IRS subframe bushings have very large holes and allows a large range of movement for the 21mm bolts that secure the subframe to the chassis.  These Delrin spacers take up the excess play within the bushing! This keeps the IRS subframe squared to the chassis and gives you piece of mind that any time you drop the subframe it will go back in the same place. As always, when modifying suspension parts on your S550 Mustang, you should have an alignment done to ensure proper tire wear going forward.
