Why a Quigley Van Makes Sense

Why is a Quigley 4x4 van the right tool for hte job? With a Quigley 4x4 va you get more passenger capacity, more cargo capacity and your cargo storage is contained and secured within the vehicle, sheltered from the elements. You get all this for either a lower cost or a comparable cost as the alternatives.


Whether the Quigley 4x4 GM component is standard to the GM Van or a standard GM component from their K-Series model line; Quigley engineers, designs and manufactures the 4x4 system with as many GM OE components as possible, for ease of service.  All non-Quigley components purchased are new, direct from GM or the GM supplier.  The various mounting brackets, adapters and other components are Quigley engineered and designed in accordance with SAE specifications.  All of these components are manufactured in house or purchased from Quigley approved vendors.
