EM37070 MAK5396-KN27000 Leveling Valve

A leveling valve helps maintain consistent ride height by controlling air flow to the suspension air springs as load conditions change. This supports stable handling, more even axle loading, and reduced driveline and tire stress. In a heavy-duty truck suspension, a properly functioning suspension leveling valve can also help protect components by keeping the chassis at the intended height.

Confirm the cross-reference MAK5396-KN27000 and compare key details such as mounting style, port configuration, and linkage/arm orientation on your current leveling valve. Match the application by vehicle make/model and suspension system type to avoid fitment issues. If you’re replacing a PAI unit, verifying the original part number and any Haldex KN27000 references can help ensure compatibility.

Incorrect linkage length or lever angle can prevent the leveling valve from reaching the neutral position, leading to over-inflation or under-inflation. Air leaks at fittings, damaged air lines, or contamination in the air system can also affect how the leveling valve regulates pressure. Re-check torque on fittings, inspect for leaks, and set ride height to the suspension manufacturer’s specification for best results.
