303.13.0001 Trailer Height Adjustment Valve

The pneumatic regulation of vehicle height is essential for maintaining stability and protecting the suspension system during operation. This high-strength component is designed to provide reliable service within the brake and air suspension systems of heavy commercial vehicles.

The 303.13.0001 is the OE equivalent of the DAF 042089956, 1291360, 500002862, FORD 4C465A687AA, KASSBOHRER 21151103110, KRONE 9450471, LIEBHERR 502918101, LOHR A05030208, LOHR A05030209, MAN 81436196004, MAN 81436196006, MAN 85500014362, MERCEDESBENZ 0003275725, MERCEDESBENZ 0003290425, MERCEDESBENZ 0003290725, MERCEDESBENZ 0003290825, NISSANUDTRUCK 522509X500, NOOTEBOOM 309104, NOOTEBOOM 567810, OTOKAR F001882, RENAULTTRUCKS 5000791019, RENAULTTRUCKS 5001871034, SCANIA 2089910, STEYR 9910036 6 and VOLVO 6773736 used in various heavy-duty models. It ensures optimal pneumatic pressure distribution across the vehicle chassis.

Engineered for durability and precision, this valve is compatible with a wide range of heavy-duty vehicles including DAF (Cargo models), MAN (various series), Scania (various models), and Volvo (F-series/N-series/B-series). It is specifically calibrated for systems requiring high-strength components to handle fluctuating load weights.

Maintenance technicians should verify the port sizes—specifically the M16x1,5 and M12x1,5 connections—prior to installation to ensure a perfect fit. Regular inspection of the pneumatic lines connected to this valve is recommended to prevent leaks in the air suspension system.
