Silver Sport transmission crossmembers are CAD-designed from heavy-duty formed and powdercoated steel. They offer strength and accuracy, two essentials of a crossmember. These SST vehicle-specific crossmembers are stiff and resistant to deflection, meeting or surpassing the original design, meaning they won't flex during hard launches or on rough roads. They are engineered to provide the proper driveline angle eliminating installation issues seen with adjustable crossmembers, as well as vibration issues and possible U-joint damage. Exhaust and ground clearance are also taken into consideration. Silver Sport transmission crossmembers locate the transmission at not only the proper height and angle, but makes sure it stays there, regardless of power, torque, or road conditions. Order the one for your specific vehicle.
