I am replacing the air bags on my F-350 and have a question.. My fiver is around 3k pin depending on trip.. The truck squats a little bit when loaded, I was thinking of going Timbren this time arou...
The differences between them and airbags are that they do nothing until contacting the axle and they are more abrupt and support more weight than airbags at low pressure which yours likely are.
Have only used them as half tons to effectively double or more what the truck could carry without bottoming out, and ultimate comfort was not my goal, but found them to be quite durable and simple. I guess effective, but not as luxurious as airbags is a good description.
