Allows easier engine swapping! This hybrid k-member bolts into a 1979-1995 Mustang chassis, and has the engine mounting pads and steering rack location to allow fitment of these engines:

  • 5.0L Coyote (2011-2014 and 2015+) See Coyote Fitment tab
  • 4.6L/5.4L modular
  • 3.8L V6
  • LSX

Get more front grip and dramatically improve the handling of your Mustang with an MM tubular K-member. At 39 lb, the MM K-member is 22% lighter than the OEM K-member, and yet it's the strongest, stiffest, and most durable K-member available.

Updated design for better fitment with 2015+ Coyote engines. All MMKM-2.1 k-members shipped after 8/1/18 are of the new design.

Better by design
MM's Engineering Team optimized the suspension geometry to increase cornering grip and produce a better-handling Mustang. A design goal was to maximize stiffness, as that keeps the suspension geometry stable when cornering. The added stiffness makes the handling more precise and increases stability under braking.

Like the OEM K-member, MM K-members are designed and built to last for the life of your Mustang. While most aftermarket K-members focus on shedding weight, our design priorities led us to create advanced cross-bracing and triangulation of tube intersections to ensure the strength and durability needed for this mission-critical part. We use thicker-gauge metal and larger tube sizes than other companies to ensure the MM K-member has the strength to handle drag race launches and wheel stands, road race use, and of course the rigors of daily street driving.


  • For installing a 5.0L, 302, 351W, 2.3L engine in a 1979-1995 Mustang, use the MMKM-1.
  • Stock front control arms won't fit because of the large size of the pivot bushings.
  • For 1979-1993 Mustangs, we make 3 different front control arms. Each does something different:
    • maintains the stock fore/aft tire location
    • shifts the tires forward 0.75"
    • shifts the tires forward 1.5"
  • For 1994-1995 Mustangs, we make 2 different front control arms. Each does something different:
    • shifts the tires forward 0.75"
    • shifts the tires forward 1.5"
  • Installation with 3.8L V6 engine requires 1996-2004 V6 engine mounts.
  • 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.
