Improve Ride Quality - Reduce Squeaks and Rattles

The Kenny Brown Extreme Matrix Chassis Brace improves the ride quality, traction, and handling of your SN95 Mustang by maximizing the strength of the car's center pan section, with minimum additional weight and no loss in ground clearance.

Kenny Brown specifically designed multiple triangulations into the Extreme Matrix Brace, as triangles are the strongest engineering structure. This design forms an "extremely" strong "matrix" under-body chassis frame; hence the name - Extreme Matrix Brace. Brown also designed the brace to be lightweight, heavy-duty, and without any loss in ground clearance.

The brace works in conjunction with Kenny Brown Jacking Rails adding four full triangulations per side for exceptional strength and durability.

Excellent for high horsepower cars, drag racing, or hard-driving applications. Great for performance street driving as well. Customers rave about the huge improvement in ride quality and reduction in annoying squeaks and rattles. Finished in OE-quality, silver zinc chromate for rust protection.
