Quantum Fuel Systems - MM Mustang K-Member Braces
The Mustang's K-member is the mounting point for the front control arms, the
steering rack, and the engine. It is a critical structural member because it
carries the loads into the chassis from the front suspension.
While the heavy stock Mustang K-member is a rather stout item, it still is not capable of handling all of the suspension forces directed into it from the front control arms. During cornering, the forces from the control arms cause the K-member to deflect, resulting in alignment changes.
The MM 4-Point K-Member brace eliminates K-member flexing by bracing across the K-member, from one side of it to the other, as well as connecting to the rearmost chassis mounting points of the K-member. The position of the MM brace provides a direct load path into the chassis for the cornering loads from the control arms. This bracing is done at the rear of the K-member (the area of greatest deflection).
In 1994 Ford made a 2-point K-member brace standard equipment on the 5.0L Mustang. All V-8 Mustangs continued to come with 2-point braces through 2004. It seems that Ford agrees with us; the Mustang needs a K-member brace!
