4×4 GM Vans
Converting your GM
Quigley Motor Company maintains a close relationship with GM due to the high quality, durable manufacturing and design of the Quigley products. This provides access to GM Ship-thru for reduced shipping costs to dealers in all 50 states and ensures you retain your factory warranty on the unaltered portion of your vehicle (engine, transmission, rear end, etc).
The proven, durable Quigley 4×4 IFS system provides improved road manners with better ride and handling characteristics, especially for on-road conditions. Maintaining the same ride height gives easy driver access and provides the ability to park in standard garages.
Quigley also offers a 3″ LIFS option for customers in need of additional ground clearance. The LIFS system will increase center of gravity and thus the vehicle should be driven accordingly. Please read warranty packet for more information concerning higher center of gravity vehicles. Quigley 4×4 conversion is available on the Passenger and Cargo Van and Cutaway (CAW).
Convert Your Used GM
In response to customer demand, Quigley will convert any 2014 or newer GM van with 60,000 miles or less to a Quigley 4×4. All vehicles must meet the Quigley pre-owned inspection before the Quigley 4×4 system is installed. Any existing components found in need of replacement during this pre-production inspection will be at an additional cost to the consumer.
The Quigley 4×4 conversion will use only new components that align with the vehicle model year. The Quigley Used / Pre-Owned conversion is sold at MSRP and will carry up to a 24 month / 24,000 mile warranty. See Pricing Guide below for a full description of costs and warranty details.
