Holland-Neway CB-4000 suspension air spring change. Original OEM #905-57-306 (aftermarket W01-358-8882) was superseded by 905-57-363 (aftermarket W01-358-9807). Depending on the suspension ride-height an additional spacer may be needed. Below is a chart (figure #1) that’ll help figure out which spacer will be needed by either the use of the original spacer or knowing what the suspension height is. The suspension ride height can also be found on the serial tag as well (figure #2).
