RE: RPO Code ZN4
What I originally thought was a vehicle manufactured during the next model year (typical cut-off is August), but VIN'd as the previous model year. Here's confirmation:
Product Availability
Due to marketing concerns, some models may have VIN badges to indicate one model year, but the engine content may actually be of a previous, or of a future year. This can cause confusion when trying to reference a Model Year (MY) for service concerns. To address this, two RPOs have been designated to indicate a MY "pull ahead" or "Push back". These RPOs (and an explanation) are as follows.
1. RPO "ZN4"
Which means a vehicle is badged for one model year while it is being manufactured into the next (pushed back). A specific case of this are some 1998 S/T pickup trucks which are VIN'd as 1998, but are manufactured after the traditional August changeover, and contain 1999 Powertrain components. These trucks would contain RPO "+ZN4".
2. RPO "ZK3"
This RPO indicated a vehicle with an indicated VIN MY that is "pulled ahead". A specific case would be the G Van which "started" 1999 MY production in May 1998, but included RPO "+ZK3", which indicated 1998 MY content. When the content switches to 1999 MY, the G Van will include RPO "-ZK3", designating 1999 MY content.
