The Midland Haldex 90555434 is a PR Plus Height Control Valve designed as a Peterbilt replacement, featuring a normally closed dump valve and an end manifold configuration. The 5.5" arm includes vertical adjustment for precise ride height setting. Air connections use Push-to-Connect fittings throughout: two 3/8" PTC delivery ports and a 1/4" PTC swivel supply port, simplifying installation without extra fittings. The non-time-delay design responds directly to suspension movement, and the tight dead zone keeps ride height variation to a minimum. Cross-reference numbers include MD90555434, HDX-90555434, and VLV00075. Call us to confirm proper fit for your application.
