K-Member Brace

The Mustang's K-member is the mounting point for the front controlarms, the steering rack, and the engine. It is a critical structuralmember because it carries the loads into the chassis from the frontsuspension.

While the heavy stock Mustang K-member is a rather stout item, it stillis not capable of handling all of the suspension forces directed intoit from the front control arms. During cornering, the forces from thecontrol arms cause the K-member to deflect, resulting in alignmentchanges.

The MM 4-Point K-Member brace eliminates K-member flexing by bracingacross the K-member, from one side of it to the other, as well asconnecting to the rearmost chassis mounting points of the K-member. Theposition of the MM brace provides a direct load path into the chassisfor the cornering loads from the control arms. This bracing is done atthe rear of the K-member (the area of greatest deflection).

In 1994 Ford made a 2-point K-member brace standard equipment on the5.0L Mustang. All V-8 Mustangs continued to come with 2-point bracesthrough 2004. It seems that Ford agrees with us; the Mustang needs aK-member brace!
