Product Description

Maximum Motorsports Engine Swap K-Member

Maximum Motorsports 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 Maximum Motorsports K-Member Unique

Maximum Motorsports K-Member lengthens the wheelbase 3/4", which improves the front/rear weight distribution and increases caster. They optimized the vertical location of the control arm pivots which improves the camber curve on lowered vehicles and improves the roll center height. The 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. Maximum Motorsports optimize the location of the steering rack for the greatest improvement in Ackerman steering geometry, which helps reduce under-steer and tire wear.

After extensive testing of anti-dive, Maximum Motorsports determined that Ford got it right! The stock amount of anti-dive is best, and that is what they built into their K-member. The MM K-Members are modular, allowing 5.0L Coyote engines to be installed in 79-95 cars, or modular engines to be installed in 79-95 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 and Pre drilled plumb bob holes for easy and accurate squaring of the K-member to the car are all features included with the K-member.

The factory Ford K-Members weigh on average 50 lbs and MM K-Member weighs 36 lbs which saves precious weight on the front end.
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, this brace will not fit.

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


4.6L Engines
