Key Features & Benefits

This little guy basically controls the air pressure in your cabin tilt system. It takes the air from your compressor and distributes it evenly to both sides of the cab lifting mechanism. It's got internal chambers and valves that move to keep everything balanced as the cab goes up or down, and it maintains that height once you've lifted it. It also releases air when you lower the cab. Think of it as a crucial part of the whole cab tilting process. It’s how you safely lift and lower the cab for engine work or other repairs under the hood. Without it working right, you’ll have an uneven lift, or it might not lift at all. It works with the compressor and the lifting rams to make the whole system function.

Symptoms, Risks & Replacements

It’s important because uneven lifting can really damage the cab mounts, the chassis, and even the cab itself. You don't want to be stressing parts that aren’t meant to handle that kind of force. A faulty valve acts like a weak link, and it’ll affect how smoothly and safely you can tilt the cab. You’ll notice if it’s failing because the cab lift will be jerky, slow, or one side will be noticeably higher or lower than the other. We actually stock these at Fixparts Online, and a lot of guys find they’re pretty straightforward to replace once they get access to the area. It's a relatively small part, but it does a big job.
