22 — Rear axle ratio: 7.17:1. This value describes the final-drive gearing between the driveshaft and the driven wheels. Browse RPO codes →
I am organizing the original options on a recently purchased 2020 Chevrolet Suburban. Code 22 appears in the list with the description “Rear axle ratio: 7.17:1. This value describes the final-drive gearing between the driveshaft and the driven wheels” Is that wording complete, or is there usually more equipment associated with the code?

A clear photo of the build label, VIN report, and the relevant component would help. Do not post the full VIN publicly; the last eight characters are normally enough for a parts-counter discussion.

If you are documenting the vehicle, save both the original wording and the readable explanation. That preserves the factory terminology while making the record understandable later.

The wording may be abbreviated because these were originally production codes rather than consumer descriptions. “Rear axle ratio: 7.17:1. This value describes the final-drive gearing between the driveshaft and the driven wheels” is a reasonable plain-English reading, but the exact implementation should be verified for the 2020 model.

A window sticker is helpful for customer-facing option names, while the build sheet is usually more detailed. If they disagree, the vehicle-specific dealer equipment list can help connect the sales name to 22.

My experience has been positive, but the benefit depends on how the vehicle is used. I would treat 22 as confirmation of the configuration, then evaluate whether that equipment matters for your driving.
