New! When choosing Rear Lower Control Arms for your 1979-04 Mustang you will find a wider selection available from MM than anywhere else. MM's new Sport Series RLCAs offer improved performance for street-driven Mustangs at a budget price. MM's new Drag Race Adjustable Rear Lower Control Arms for Mustangs with Big Power are rated at 1,000 rwhp, and provide ride height adjustability to tune for the optimum launch. These two new series join MM's Heavy-Duty, Extreme-Duty, and Road Race control arms.

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

Read the Muscle Mustangs & Fast Fords magazine article about their installation of an MM K-member into an SN95 Mustang.

Read the Car Craft magazine article about their installation of an MM K-member into their Fox 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 1979-95 Mustang, use the MMKM-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.
