All MotoTote carriers come with all parts you need to haul safely. Upgraded parts can customize the carrier's fit to your vehicle, extending, lifting, or lowering it. Additional parts are planned to be added in the year 2023.
Exchanging parts is simple as the MotoTote is assembled with a minimal amount of hardware. All parts are accessible by removing one to two bolts/nuts.
Yes, since they are both built off the MTX platform, you can interchange parts between the carriers. The only exception is the Sport tire track and wheel stop are not compatible with m3 and Max/Max+ carriers.
