Made out of 2x3x.083" wall mild steel tubing. These mandrel bent frame rails do not have the ugly wrinkles under the bends like other manufactures. Kit allows you to lower the front of your drag race car and take off 200 to 300 pounds of unwanted weight. Ground clearance is 3-1/2" at the firewall. The frame rails are long enough to extend from under the car to the rear frame crossmember. Designed for eye-mount VariStruts or Strange struts. Kit includes a pair of frame rails; forward struts to attach to your roll cage; tube rack-&-pinion mount crossmember; upper strut mount tabs; lower control arm mount tabs; hardware; drawing and instructions. Shipped unassembled by UPS.
