R-017521-27 Hendrickson Replacement QRV Kit

The Hendrickson R-017521-27 Replacement Quick Release Valve (QRV) Kit is a critical component used to manage air supply for heavy truck auxiliary lift axles. This kit is identical to Hendrickson Part Number A-40713 and serves as a direct ride-bag-mounted component for updated LC Air Control Systems.

OVERVIEW:
The R-017521-27 Hendrickson Replacement QRV Kit is as pictured and the following is for reference only.

• Hendrickson updated its LC Air Control Kits to utilize a more compact secondary valve assembly. This change alters how quick release valves are installed
• • The Elimination: They removed the bulky integral QRV from the secondary valve.
  • The Replacement: They replaced it with two separate QRVs mounted directly to the ride bags.
  • The Rule: You must install this kit if you update an older LC system to the new compact valve.
  • Date Cutoff: Systems shipped after June 1, 2021, already include these individual QRVs.
