  • Payload A is 1.2 VAI Permit (based on axle reference x 1.2)
  • Payload B is 1.3 VAI Permit (based on axle reference x 1.3)

Once you have determined the recommended option or options, get in touch and we can work through detailed requirements, specifications and pricing with you. If you are still unsure of what you need, no problem, we are here to help.
