Actual product may differ from photo.


  • Item # MMSM-2
  • Manufacturer: Maximum Motorsports

Shock-to-axle mounting bracket is a robust replacement for the OEM double-shear lower shock bracket. Unlike the OEM bracket, the MM design is suitable for use with a coil-over conversion.

Better by Design

  • Stronger than OEM double-shear brackets, and with a stronger 2-bolt attachment to the axle.
  • Allows installation of later model Mustang shocks that require a double-shear lower bracket to Mustangs not originally equipped with double-shear brackets.
  • Required upgrade for rear coil-over conversion; OEM double-shear brackets easily fail in a coil-over application.
  • Thicker steel than OEM bracket
  • Two mounting bolts, each larger than the single OEM stud
  • Zinc-plated
