-  Design optimized using CAD/CAE software combined with real-world chassis deflection test data.- Full length, manufactured of 1.5 x 2 x .083 rectangular tubing for the ultimate in stiffness, reduced   weight and maximized surface area between subframe and connector.- Integral laser-cut cross-brace reduces free span, reinforces floor pan and minimizes required   welding during installation.- Industrial grade powder coat for long life, to outlast the vehicle.- Pre-masked areas for welding require NO removal of powder coat before installation, for   significant time savings!- Crimped and welded tube ends seal out moisture while also increasing strength.- Engineered to contour subframe for an exact fit with no loss of ground clearance.- Can be used alone or with Stifflers Fully Integrated Technology (FIT)SystemTM.
