• Designed to accommodate the Hellion turbo system for 4.6L modular engines.
• Improves suspension geometry. The MM K-member has two sets of holes for mounting the front control arm pivots. The lower holes are raised 1" from the stock position. The upper holes are raised 2". This allows installing the front control arms in the best pivot location to optimize the roll center height and improve the camber gain for the ride height you choose for your Mustang.
• Front control arm mounts are shifted 0.75" straight forward. This increases positive caster and moves the center of gravity slightly rearward for improved weight distribution with the non-offset and forward-offset front control arms.
• Forward shift of the control arm location increases the Ackerman steering effect with the non-offset and forward-offset front control arms, which improves initial corner turn-in and reduces understeer.
• Lighter weight than a stock K-member: Installation of complete MM K-member system reduces vehicle weight by nearly 40 lbs.
• After extensive testing of different anti-dive geometries, we determined that Ford got it right! The stock amount of anti-dive provides the best performance, and that's what we build into the MM K-member. Increasing anti-dive geometry over the stock amount, as some other K-members do, causes the suspension to bind during hard braking and makes the front brakes lock up easily.
• Improves maintenance access.
• Designed to make steering rack removal easier than with stock K-member or other aftermarket K-members.
• Stiff design prevents flexing, which improves steering response and handling.
• Tough enough for street, strip, and road course use.
• Precisely located holes allow easy use of plumb bob strings to square the K-member to the chassis during installation.

• Raised front control arm pivot points; 2 positions accommodate the ride heights of both street-driven Mustangs and race cars.
• Control arm pivot points move straight forward 0.75".
• Fore/aft tire location is determined by which MM Front Control Arm you choose. See the Fitment tab for tables showing the front tire location when various MM Front Control Arms are installed with any of the MM K-members.
• 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 (both stock and aftermarket K-members need a brace).
• Control arm pivot points located the same distance from the vehicle centerline as 1996-2004 V8 Mustangs.
• Maintains stock engine mount height for best oil pan clearance.
• Maintains stock 4.6L engine fore/aft location.
• No modifications needed to the engine mounts, unlike many other aftermarket K-members that require removing the anti-twist feature.
• Includes features to ease squaring to the chassis during installation.
• Includes 2 MM Low-Profile Front Control Arm Bolts for improved clearance between the rubber steering rack boot and the heads of the two forward pivot bolts.
• Superb installation instructions
• Black powdercoating for protection and good looks
• Designed by the MM Engineering Team.
• Track tested by winning American Iron racers: too many to count.
• Made by MM in San Luis Obispo, California. Beware of poor-quality copies made overseas!

How much is weight reduced with a k-member?
Tech: Weight Myths about K-members

Fits

• 1996-2004 Mustang with Hellion turbo system and 4.6L modular engine.
• Most aftermarket tubular front control arms

Tables below show the front tire location when various MM FCAs are installed with any MM K-members.

• 4.6L modular engines that have an OEM oil cooler require an Oil Filter Relocation Kit
• 1996-04 with MM Forward-offset Front Control Arms require Front Swaybar Relocation Brackets
• Has clearance for Canton 15-784 oil pan.

Does NOT fit:

• Stock Ford front control arms
• Stock location springs; coil-over conversion is required
• 1979-1995 Mustang chassis
• Any steering rack bushings other than MMST-6

Fore and Aft Wheel Location
The fore-aft location of your Mustang's front tires may change after installation of an MM K-member and Front Control Arms. How much it changes depends on the specific combination of parts you install. Scroll down to see images showing the results of several combinations of parts installed on SN95 Mustangs.

Required Modifications
1996-2004 Mustang
All combinations of MM K-members and MM Front Control Arms move the front tire location forward. Some may require slight modifications; how much depends on the tire size, wheel offset, and how far forward the tire goes. In general, 0.75" rarely requires any modifications unless an uncommonly large tire/wheel package is installed. 1.5" of movement may require modifications to the plastic inner fender liner, and trimming the end of the bumper fascia inside the wheel well.

For more information about these modifications, email the MM Tech Department from the Contact Us page. Be sure to include the part numbers of the K-member and front control arms you will use, as well as the year, model, and sub-model of your car.

The images above show the results of several combinations installed on a 1994-2004 Mustang.

Left image: No change in tire location, using either:

• Stock K-member and stock front control arms
• Stock K-member and MM Non-Offset Front Control Arms

Middle image: Tire moved forward 0.75", using either:

• MM K-member and MM Non-Offset Front Control Arms. The MM K-member adds 0.75" of forward offset.
• Stock K-member and MM Forward-Offset Front Control Arms. The MM Forward-Offset Front Control Arms add 0.75" of forward offset.

Right image: Tire moved forward 1.5", using:

• MM K-member and MM Forward-Offset Front Control Arms. The MM K-member adds 0.75" of forward offset and the MM Forward-Offset Front Control Arms add another 0.75" of forward offset, totaling 1.5" forward offset.
