Product Overview

GM Products Overview

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 4x4 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 4x4 conversion is available on the Passenger and Cargo Van and Cutaway (CAW). See Models and Pricing for further details.

GM Warranty Program

The Quigley 4x4 system is backed by a warranty matching GM's vehicle warranty including both labor and replacement parts. Designed to be easily serviced by GM dealers across the country, the genius behind Quigley is its use of easily obtainable, original equipment suspension and drive train components from major automotive manufacturers.

Extended Warranty: When purchasing extended warranties either from the vehicle manufacturer or an aftermarket company, verify in writing the extended warranty is valid for vehicles converted to the Quigley 4x4 system. The vehicle manufacturer's extended warranty covers only the factory installed components. Quigley Motors does not offer, nor does it honor, any form of extended warranties.
