      Ensure Your Mustang’s IRS Subframe is Always Aligned Right. Despite the great looks, performance, and engineering of the Mustang, the subframe mounting holes for the independent rear suspension on the S550 GT 5.0 are overly large, making it possible for the crossmember to be misaligned when installed, potentially causing problems with suspension alignment. Even from the factory, these crossmembers have sometimes been found to be out by more than half an inch! Quickly and easily banish this problem by using this Rear Subframe Alignment Kit from J&M Products.

      Quality Billet 6061 Aluminum for Fine Precision and Light Weight. The alignment bushings in the Subframe Alignment Kit are CNC machined from solid billet 6061 aluminum, providing great strength and precisions. They are protected from corrosion by a clear anodized coating to Mil A 8625 Type 2 specification. These CNC machined billet aluminum sleeves provide for easy, accurate alignment and installation of the crossmember.

      Lifetime Limited Manufacturer Warranty. J&M Products ensures its Subframe Alignment Kit with a lifetime limited warranty.

      Application. The J&M Subframe Alignment Kit fits the Mustang GT 5.0 from 2015 to 2020.

        Reduces the booty wiggle

        The stock IRS subframe can be off by as much as 1/2". This alignment kit puts the subframe where it needs to be at all times. Eliminates that wobbling feel during hard accelerations.
