Attention! Please Read

GM PZN is a former generic module replacement supplied by dealers that is no longer available. Due to this module being used to field replace OE Modules it's calibration is unknown in your specific replacement need. The best way to get the correct replacement is to have a module created that matches your vehicles current tire size and differential gear ratio (which can be acquired by calling a GM dealer's parts department with the last 8 digits of your VIN). Please use the product options to create an exact replacement module based on your vehicles information.

Module Type

Select the module type that best matches the year model of the vehicle the replacement module is going into. We will compare this selection to the additional information provided such as the vehicle details and provide what is correct. There are years that different type units were used and we are aware of those crossover years and know what is compatible, don't worry too much about this selection being an issue, leave that to us.

Gear Ratio

To find your vehicle's Rear End (differential) gear ratio, the RPO codes list in your glove box is the easiest way. This is the sticker inside the box with a lot of 3-character codes. Find the gear code, this is typically GU4 (3.08) GU6 (3.42) GT4 (3.73) and GT5 (4.10) being the most common. Another method, you can call a GM Dealer's service department and provide them with the last-eight digits of your VIN and they can tell you the factory build gear ratio.

Tire Size

Check the current tire size on the vehicle. The absolutely preferred tire size measurement will be to use the P-Metric size on the sidewall. For example: 245/75 R16, please do not provide an estimated tire size diameter when a P-Metric or true size (like 33x12.5 R15) is available as this greatly affects accuracy of calibration.
