Us Stock Upr Products Rear Lower Control Arm Bearing Kit (15-19 Mustang) [limited Qty] [bm28Gu4C]

UPR IRS Subframe Alignment Kit for 2015-2018 Mustangs. CNC machined from Delrin to help align the factory IRS subframe that can come misaligned from the factory. The factory IRS subframe has very large holes and allows a large range of movement and our Delrin spacers take up the excess play. This keeps the IRS subframe squared to the chassis and gives you peace of mind that any time you drop the subframe it will go back in the same place.

Upon installing the spacers you should have an alignment done in case the IRS subframe was not square from the factory.
