Offering a lower cost alternative to our Matrix Chassis Frame Connector Brace,these true full-length connectors run the entire length of the floor pan for increased chassis rigidity, better handling and improved ride.  We use round chrome-moly tubing and these sub-frame connectors are designed to have no ground clearance issues.  We spent countless hours figuring out where theLX's and Challenger could benefit most from chassis stiffening. Here is the end result....Made from 4130 Chro- Moly material, It ties together  the frame rails and the rear lower control arm mount. Braces are powder coated our customary texture black for a long lasting finish. These are a weld in installation for maximum benefit .  These are perfect for serious cars with high horsepower, sticky tires or competition suspension.  * These tuck in very close to the underside of the chassis and hang only as low as the side skirts
