MM News

MM in print: 5.0 Mustang & Super Fords magazine asked us to help with the Tech for an article titled "Full Plate," published in the new (June) issue. The article details the many differences in caster/camber plates required to cover the variations in Mustang strut towers from 1979-2014. Read it, and then impress your friends with your knowledge of camber plates and alignments.

MM K-member for 1979-95 Mustang with engine swap to 4.6L/5.4L modular, 5.0L Coyote, or LSX engine.

See the K-member packages that include all you need to install a MM K-member on your Mustang.

Read the Car Craft magazine article about their installation of an MM K-member into their Mustang project car.


  • Allows engine swaps: Install 4.6L/5.4L modular, 5.0L Coyote, or LSX engine into a 1979-95 Mustang.
  • Unlike k-members designed for 1996-04 applications, this version fits the 1979-95 chassis.
  • Replaces the stock k-member with improved version designed by MM.
  • Lighter weight than stock k-member: Installation of complete K-member system reduces vehicle weight by nearly 40 lb.
  • Improves suspension geometry.
  • Moves roll center vertical location to optimum position.
  • Improves weight distribution.
  • Allows increase in positive caster.
  • Improves maintenance access.
  • Easier steering rack removal than stock or other aftermarket k-members.
  • Stiff design prevents flexing.
  • Tough enough for street, strip, and road course use.


    • Raised front control arm pivot points; 2 positions accommodate the ride heights of street-driven Mustangs and racecars.
    • Control arm pivot points are moved straight forward 0.75"
    • Fore/aft tire location is determined by which MM Front Control Arm is chosen.

  Fore/aft tire location
MM control arm type 1979-93 1994-95
Reverse-offset Stock location Not available
Non-offset 0.75" forward 0.75" forward
Forward-offset 1.5" forward 1.5" forward

  • Accepts fitment of other aftermarket front control arms that replicate the stock control arm pivot bushing locations, and have smaller than stock bushings.
  • Includes a 2-point chassis brace (stock k-members need a brace, and so do aftermarket k-members).
  • Maintains stock engine mount height for best oil pan clearance.
  • No modifications need to be made to the engine mounts, unlike many other aftermarket k-members.
  • Includes features to ease squaring to the chassis during installation.
  • Superb installation instructions
  • Powder coated black
  • Designed and track tested by MM's engineering team.
  • Made by MM in the USA. Beware of the poor quality copies made overseas.

Items required for installation

Items recommended


  • Steering rack height is the lower 1996-04 location, not the earlier height.
  • Complete k-member packages are available. This MMKM-2.1 may be substituted into any existing MM k-member package; call to order.
  • For installing a 5.0L, 302, 351W, 3.8L, or 2.3L engine in a 1996-04 Mustang, use the MMKM-1.1.
  • Stock front control arms will not fit because of the large size of the pivot bushings.
  • Has clearance for Canton 15-784 oil pan.
  • LSX engines require fabrication of engine mounts, or Ford modular engine mounts can be modified to fit the LSX block.
