If you do not need the full belly build-out but want the expensive parts covered, this is a sensible place to start. Rival's technical description lists three parts in 6.0 mm aluminium protecting the engine, gearbox and muffler.

A conflict in the manufacturer's data. Rival's catalogue name lists five areas (engine, gearbox, transfer case, exhaust, fuel tank) and model years 2017-2021, while the technical description for the same part number gives a three-piece set — engine, gearbox, muffler — and 2018-2021. We state the contents from the technical description, because that is the one naming the individual parts.

That is the most exposed zone on the vehicle: whatever ends up under the front of a JL on a climb or coming off a ledge hits here first. A plate of this thickness lets the Jeep slide over an obstacle rather than hang on it.
