We already publish a parts guide for each HQ model and a compatibility guide that tells you which parts cross over between them. This page is the third way in: by system. If you know the water pump is dead but do not know what else to check, or you want to see everything the electrical side of an HQ19 might need over five years, start here. Every section links to the genuine OEM part and, where we have one, the how-to that goes with it.
All parts below are in the Black Series HQ Camper Parts (Genuine OEM) collection, filtered by model in HQ12, HQ15, HQ17, HQ19 & HQ19T, HQ21 & HQ21B, and HQ22T. Note that free shipping has a Black Series exclusion on some heavy OEM items; the product page states it.
Doors, locks, and steps
The entrance door takes more abuse than any other part of an HQ. Corrugated roads work the lock and hinges loose, and the seal compresses with age.
- Entrance door lock. The OEM Entrance Door Lock & Key ($130.00) is the standard replacement; 2019–2021 campers use the Door Lock Assembly 2019-2021 ($249.00). Diagnose first with the door lock troubleshooting guide, then follow the lock replacement how-to.
- Handles and hinges. Chrome Entry Door Handle ($50.00), Black Door Hinge ($50.00), Inside Door Hinge ($40.00).
