this is a universal air horn valve,if your looking for a way bigger airflow valve over the stock one then this is a upgrade by far lol.
and its super easy to hook up verses the stock pullstring usually located up on the roof.
its made for your bigger air horns that require more air and it makes it sound way better.
a nice smooth train horn sound if paired with the 3 trumpet grand general horns .....
