The Hendrickson VS-33704-3 is a height control valve (leveling valve) for the ULTRAA‑K trailer air suspension.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It automatically adds or exhausts air from the air springs to keep the trailer at a constant ride height regardless of load. The valve is commonly replaced when it leaks, sticks, or fails to maintain proper suspension height, which can cause uneven tire wear or poor ride quality.
