MM Struts: Better by Design
MM's Engineering Team created a robust strut housing that contains an inverted monotube insert with MM-specified valving.

  • Exclusive MM valving is the key to superb performance and good ride quality for the Street and Sport series. The Race series fulfills the goal of excellence at the track.
  • Robust, high-grade alloy steel strut mounting ears on the proprietary MM-designed and -manufactured housings prevent bending from the high brake-reaction loads resulting from today's sticky tires and high-grip brake pads.
  • Coil-over ready; no modifications required for the MMCO-1 kit.
  • Monotube design provides superior damping.
  • The inverted design allows for large strut shaft bushings, providing more resistance to deflection from cornering loads.
  • Reduced fading through high gas pressure and monotube design.
  • Choice of applications: Street, Sport, or Race.

See the Spring Rate tab for a list of spring rates that each MM strut series will control.

Spindle fitment
These struts fit:

  • 1987-1993 Mustang V8 spindles.
  • 1984-1986 SVO Mustang spindles.
  • All 1994-2004 Mustang spindles.
  • 1987-1988 Thunderbird Turbo Coupe spindles.

MM Struts: Better by Design

  • MM-designed damping curves for high-performance driving
  • Monotube design
  • Nitrogen gas pressure
  • Inverted design results in very large shaft for increased resistance to deflection.
  • Internal bumpstop
  • MM-designed and -manufactured housing has high-grade steel mounting ears to eliminate bending from brake-reaction loads.
  • Dustcover included with Street series.
  • Race series has altered spindle-mounting ear location to increase bump travel by 9/16".
