STRATEGY In keeping with our goal of providing our customers with the best possible value, we have tested a large group of components specifically designed for the 4.6L 4V Mod Motor. We have invested many hours evaluating and refining each of the 4.6L products on our chassis “dyno”, to ensure that we could develop as much power as possible, as safely as possible. The site menu on the left side of this page, lists the clear winners when it comes to “performance vs. dollar” value. Please check back often as we are always developing new ways to create more horsepower.

KENNY BROWN Extreme Matrix Subframe System
Flex Your Muscle, Not Your Chassis with the Extreme Matrix System
for the 1996-04 Mustang and Cobra

The heart and soul of chassis support is the Matrix System which consists of the Super Subframe Connectors, Jacking Rails and the Extreme Matrix Brace.

The Subframe Connectors tie the front and rear subframes together, the Jacking Rails (very handy when jacking up lowered cars) run along the outer rocker pinch-weld and the Extreme Matrix brace connects the two with 4 full triangulations per side.

Remember that triangulation is the lightest and strongest engineering structure. The Extreme Matrix system basically puts a mini-frame under the center of your car.

The Kenny Brown Extreme MATRIX Sub-frame System consists of the following.

Double-cross Subframe Connectors The Double-cross tie the front and rear sub frames together. Adds additional strength and tensional rigidity to the chassis that further reduces twisting action and helps extend the life of the floor pan.	KBP-29004SPR $ 104.50
Jacking Rails Originally designed to add structural rigidity while providing convenient hard points along the side of the car for NASCAR style tire changes. Advanced engineering has made the jacking rails an integral part of the Extreme Matrix Sub frame System.	KBP-29010 $ 109.50
Extreme Matrix Braces Extreme Matrix Braces tie this system together; if you have a convertible this system is mandatory for body strength and chassis longevity. The Extreme Matrix Brace acts as a bridge between the jacking rails and the Double Cross Super Sub-Frame Connectors to take chassis stiffness to a new level. This is the foundation for the stiffest Sub-frame system on the market.	KBP-28019 $ 204.50

KENNY BROWN Double-Cross Super-Sub Frame Connectors KENNY BROWN Super Subs are zinc chromate plated to help prevent rust. Great for convertibles, T-tops, competition or extreme use. The Double-Cross™ subframe connectors improve handling, feel, weight transfer and extend the life of the car by reducing power-robbing chassis flex and strengthening the unibody. The Double-Cross™ subframe connectors is the heart of Kenny’s Mustang chassis support system, uniting together the front and rear subframes, to strengthen the center of the car. An added feature to the subframe connectors is the unique Double-Cross™ design, which reduces twisting action and cuts the free span of the car in half by attaching the cross section of the subframe connectors to the strongest section of the midpan.
