These frame boxing sets are designed to reinforce your failure prone factory frame. The standard kit boxes the frame rails for the entire length of the frame for the ultimate in strength.  Fabrication and welding are required!  This kit works with the stock motor mounts and cross members.  It also comes with machined DOM sleeves and grade 8 hardware for the steering box to reinforce that trouble prone area, outer plates are available seperately.  Say goodbye to frame cracks and ripped off steering boxes, while stiffening the chassis for better handling and performance.  Made in the USA!
