Vehicle Suspension Information (VSI) Forms
In order to provide you with the best chain unit for your application and reduce lead time for your Insta-Chain system, please fill out the Vehicle Suspension Information (VSI) form as correctly as possible. All of the information is important to the design of your system. When there is missing information, our engineering department has to guess or make additional phone calls to verify information.
There are a few vehicles that do have standard brackets. Consult an Insta-Chain representative if you have any questions.
