AB,

Realistically, there is only one "version" of the GENESIS. However, we always are striving to improve our products. Therefore, we have infact made changes to the GENESIS over time to improve parts, suchas differentials, spur gears, and so on.

Yes, the latest change is a brace holding the center transmission's top shaft in place. This strengthens the truck's main spur gear system quite a bit. The part # is GS097. If your truck does not have this brace, you should contact the local CEN Representative and they should be able to help you out.
