Rear air springs (bags) that install alongside the factory leaf springs to add up to 5,000 lbs of load-leveling support for towing/hauling, with an internal jounce bumper for stability, and no-drill installation.

why this one — Specifically the "Ultimate" trim of Air Lifts LoadLifter 5000 line (adds the internal jounce bumper over the base LoadLifter 5000), sourced with a real 2011-2019 2500HD/3500HD 2WD/4WD fitment confirmation rather than assumed from the base product line.

why no number is shown

Load-support air spring kit, not a power-related part.
