Product Highlights

  • Intelligent Leveling Logic: Features a high-precision white linkage gear system that automatically maintains the pre-set seat height, ensuring consistent driver ergonomics across bumpy terrain.

  • Leak-Free Brass Connections: Our valve is equipped with genuine brass threaded inlets for air lines, offering superior pressure resistance and durability compared to standard plastic ports.

  • Direct OEM Integration: Designed specifically for the MSG 90.6 chassis used in most European heavy trucks. It is a direct "drop-in" replacement for the original Grammer leveling unit.

  • Engineered for Reliability: Built with automotive-grade composite materials and high-tension internal springs to withstand millions of regulation cycles.

⚠️ IMPORTANT: BUYER'S GUIDE (TECHNICAL VERIFICATION)

  1. LEVELING GEAR CHECK: Inspect the white plastic gear section of your old valve. Ensure the tooth pattern and mounting points match our high-resolution photos.

  2. AIR PORT COUNT: Verify whether your seat uses 2 or 3 air lines. This valve is designed for the standard MSG 90.6 configuration with brass fittings.

  3. SYMPTOM DIAGNOSIS: If your seat collapses to the bottom or rises to the maximum height without stopping, this leveling valve is likely the cause.

  4. MOUNTING ORIENTATION: Take note of how the mechanical linkage connects to the seat frame before removal. Incorrect installation of the lever can lead to improper leveling.
