Product Description

We spent over two years optimizing our K-Member, both on the track and on the computer. The result is that the front of your car will corner like nothing else you’ve experienced. Unlike other K-Members on the market, strength, stiffness, and durability are given a higher priority than ultra-low weight so that your investment will last the life of your vehicle.

What makes our K-Member unique:

Our K-Member lengthens the wheelbase 3/4", which improves the front/rear weight distribution and increases caster.
We optimized the vertical location of the control arm pivots. This improves the camber curve on lowered vehicles and improves the roll center height.
Our K-Member offers two different vertical locations for the control arm pivots, allowing you to choose the one that's best for your car's ride height.
We optimize the location of the steering rack for the greatest improvement in Ackerman steering geometry, which helps reduce understeer and tire wear.
After extensive testing of anti-dive, we determined that Ford got it right! The stock amount of anti-dive is best, and that is what we built into our K-member.
Our K-Member allows 5.0 engines to be set back one inch.
The MM K-Members are modular, allowing 5.0 engines to be installed in 96+ cars, or modular engines to be installed in pre-96 cars.
Increased oil-pan clearance for all aftermarket oil-pans means oil-pan service is easier.
Header clearance is increased by over 1" in critical areas.
Easier access to the starter motor.
Pre drilled plumb bob holes for easy and accurate squaring of the K-member to the car.
The factory Ford K-Members weigh on average 50 lbs. The MM K-Member weighs 36 lbs.
Included with each MM K-Member!
Every MM K-Member comes standard with a two point K-Member Brace (see photo above). If you have a Canton Oil Pan on your 4.6L engine, note in special order instructions, and note to swap MMKB2-5 (also available separately below) for the standard MMKB2-4 which is normally included.

4.6L Motors
5.0L Coyote Motors
LSX Motors

Proper installation of the K-Member will also require the use of the following parts:

Tubular front control arms (stock control arms are not compatible because of the large outside diameter of the pivot bushings)
Caster/Camber plates
Front Coil-Over conversion kit
Aluminum steering rack bushings
MM Adjustable Tie-Rod Ends
MM Oil Filter Relocation Kit when installed on a 4.6L 4V Cobra modular engine

Image uploaded by James M. One AMAZING product! The quality and fitment of Maximum Motorsports components are superior to those of other manufacturers! The K member install was super easy with the supplied install instructions. The k member is made to be strong and lightweight and also looks good too. Frees up a ton of space to access other engine and suspension components.

Yes, I would recommend this item to a friend!
