The basic haydenauto.com type clutches spin 90% when hot, and this motor has ~4000rpm redline so not very fast, and dual belts.
I actually assume that the new RAMs etc with clutches have the matching large hub plastic fan like https://www.summitracing.com/parts/hda-8302
One concern is why these have 4-5 pins... if they expect CAN data it is a non-starter.

These for RAM 1500 https://www.ebay.com/itm/296187407367 might actually be an alternative if they can actually pull more air than the 1200cfm aftermarket models.

These https://www.dieselarmy.com/news/quick-hit-flex-a-lites-electric-fans-equip-diesels-for-long-hauls/ sell for ~$700

flex-a-lite type fans are an attractive option for their ability to run after shut-off and relieve hot-soak. But not $700 attractive.
