STANDARD MANUFACTURING SPECIFICATIONS FOR ALL FRAMES

We have the most state of the art frame jigs in the industry.  They are CNC machined to exact tolerances from steel and billet aluminum and weigh approximately 800 lbs. a piece.  Wrench frames are designed based on a center line to keep the tire perfectly in the center of the frame.  Each fixture has a center line scribed into it's surface as well as each back bone that is jigged.  These are lined up with a laser line as the frame is jigged and checked with the laser before unjigging the frame to check for movement.  Each chassis is welded using the latest TIG welding technology and is fixtrue cooled over night .  Wrench frames also go thru a ten step digital level process before shipping.
