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.
Fits these engines:
- 4.6L modular, 2V and 4V
- 5.0 Coyote (2011-2014)
- 5.4L modular
- 3.8L V6
- LSX
New!
Updated design for better fitment with 2015+ Coyote engines. All MMKM-2 k-members shipped after 6/7/19 are of the new design.
Benefits:
- 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.
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.
Features:
- 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.
- 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!
Required for installation
- Tubular front control arms
- Front coil-over conversion with high-performance struts
- MM Aluminum Steering Rack Bushings
- Caster camber plates
- Bolt-through-style bumpsteer kit
- 4.6L modular engines that have an OEM oil cooler require an Oil Filter Relocation Kit
- Short swaybar endlinks
- Front Swaybar Relocation Brackets
- Universal Front Swaybar Bushings
Recommended
- Solid steering shaft
- Strut tower brace
Notes
- For installing a 5.0L, 302, 351W, 2.3L engine in a 1996-2004 Mustang, use the MMKM-1.1.
- Stock front control arms won't fit because of the large size of the pivot bushings.
- For 1996-2004 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.
