Vehicle center of gravity and axle weight calculator

NTEA’s Vehicle Center of Gravity and Axle Weight Calculator is a web-based, interactive tool that provides vehicle specification and weight information.

When upfitting or modifying a vehicle, these calculations produce information to share with customers, and assist in understanding how certain industry standards may apply — both in spec’ing prior to purchase and after upfitting is complete. Interactive instructions make this a user-friendly, additional tool for those in your company who are responsible for weight distribution and center of gravity calculations.
