Manufacturing & Engineering
Engineered to meet your needs, our four-wheel-drive system's design is the cornerstone of our business. We can offer you the value and performance of our proven O.E.M. four-wheel-drive system for new GMC / Chevrolet full-size vans. Some of the added benefits include improved ride and handling characteristics, lower center of gravity, no lock-out hubs and consisting of 95% GM parts. For more details on our components please view our GM 4x4 Components page.
At Quigley Motor Co., Inc., safety and quality are our top concerns during our engineering and development processes. The 4-wheel drive system has been engineered to maintain all safety features. The four-wheel ABS, Stabilitrac and Tire Pressure Monitoring System (TPMS) are retained if equipped. QMCI uses a number of independent testing facilities to verify functionality. All vehicles must pass a rigorous Quality Control Process before they are released for shipping.
Here at Quigley Motor Co., Inc. we must meet a number of safety and automotive standards; not only set by the auto makers themselves, but also by the United States Federal Government. Quigley adheres to all applicable Federal Motor Vehicle Safety Standards (FMVSS) to provide the safest, highest quality products. All parts manufactured to the company’s engineering designs are in accordance with Society of Automotive Engineers (SAE) best practices.
We take pride in maintaining these safety / automotive standards; and in the quality of our engineering and workmanship, to offer our customers the peace of mind they are accustom to from the Detroit auto makers. (It's no coincidence that we are oldest and leading manufacturers in this industry.)
