R-017521-23 Replacement Secondary Valve Assy R-017521-23 Replacement Secondary Valve Assy OVERVIEW: The R-017521-23 Replacement Secondary Valve Assy is as pictured and the following is for reference only. Hendrickson Specialty Products – Auxiliary Axle announces a change to our LC Air Control Kits. The secondary valve assembly has been redesigned to be more compact, resulting in easier installation. The most obvious difference is the integral Quick Release Valve has been replaced by two individual Quick Release Valves (QRVs) that must be mounted to the ride bags. The LC Air Control Kits will now include airline fittings for the ride and lift bags as well. New LC Air Control Kit orders scheduled to ship on or after June 01, 2021 will be to the new revision. If you installed a pre-plumbed suspension or pre-plumb kit, then the two individual QRVs would already be present. All pre-plumb suspensions will include the new LC secondary valve assembly pre-installed. The new secondary assembly (by adding the QRV) is retro compatible with the prior version LC Air Control System with the addition of the ride bag mounted QRV (R-017521-27 or Watson Chalin Air Spring Mini Quick Release 17517).
