Height Control Valves

Height control (leveling) valves keep air-ride suspension at the correct ride height by adding or exhausting air as the load changes. We list 25 from Hadley, Barksdale, Hendrickson, Haldex, OTR, Power Products, World American, Predator HD and PAI.

Coverage includes Hadley H00450CE (also as Power Products 450CEP), H00600P (and OTR OTRH00600P) and H01501UD (replaces 2607243C91); Barksdale KD2510 for Freightliner 18-58444-000; Predator HD valves for Barksdale KD2510, PACCAR KD2445 and Peterbilt 08-02947; a 2006-and-newer Volvo valve replacing Barksdale KD2503; Hendrickson VS-29392; Navistar valves through PAI 450440 (2505183C92) and PAI LCV-3721 (3606780C91); and the OTR70040 cab height control valve (replaces WABCO 4640070040).

Match the valve number and the arm orientation, then set ride height to the truck maker's specification after installation. Air springs are in air springs.
