Dodge issues frame alteration information for Ram

Dodge Truck Engineering has issued frame alteration information for its 2004-model-year Ram pickup truck.

DaimlerChrysler Corp doesn't recommend any modifications or alterations to the frame assembly. Modifications or alterations (ie, hole drilling, welding, etc) to the frame assembly are the responsibility of persons performing these modifications or alterations.

These procedures and specific precautionary instructions are recommended for proper installation of special bodies and/or equipment on the Ram frame:

Holes are not to be drilled in the top or bottom of the frame rails. Holes to mount outriggers, brackets, and supports must be drilled in the web (vertical sides) of the frame rail with these restrictions:

  • Hole diameter should not exceed 20 mm (0.75").

  • Material between edge of hole and top or bottom of the frame rail must not be less than 40 mm (1.60").

  • The minimum edge distance between any two holes must be larger than twice the diameter of the larger hole.

  • Any thru-fastener that torques down on both external surfaces of the rail must use an internal spacer to prevent crushing the rail tube.

  • All holes should be drilled in the frame using appropriate drilling practice and safety precautions.

  • Avoid drilling holes near the fuel tank, fuel and brake lines, and other lines and wires to avoid damage to them.

Before any welding, these things must be done:

  • Avoid welding near the fuel tank, fuel and brake lines, or other components that may be damaged by the heat of welding. If it is necessary to weld near these areas, use wet cloths to cover these components. If it is necessary to remove the fuel tank, lines or other components, do it in accordance with applicable service manual procedure.

  • Components near the welding area that could be damaged by excessive heat must be removed or adequately shielded.

  • Disconnect any batteries.

  • Precautionary measures should be used to prevent electrical system components or wiring damage.

  • Frame e-coating must be removed from welding and surrounding area.

Use proper welding techniques to avoid stress risers that may adversely affect frame performance.

After welding:

  • Carefully inspect electrical components and wiring for shorts or other damage.

  • Apply protective coating to areas where coating was removed.
