ATTACHMT: Attached to letter dated 6/30/94 from John Womack to Blair Abraham (A42; Part 567)

TEXT: I am looking for the steps to take to certify a vehicle for a higher weight rating than what is issued by the manufacturer. We modified the suspension to enable the vehicle to handle an additional 1000 pounds. The GVWR is stamped at 5600 pounds. With our new suspension kit, we would like to certify the vehicle for 6600 pounds.

If we cannot increase the GVWR, are we liable for non-compliance of a DOT regulation if we exceed the GVWR?

Please send me the information required for increasing the GVWR and coded regulation of compliance.
