j hancock Posted February 12, 2015 Share Posted February 12, 2015 That is Mack inverted camel back suspension. 2 Quote JimIt doesn't cost anything to pay attention.

Superdog Posted February 12, 2015 Share Posted February 12, 2015 What Jim said. Very popular in the '60's for highway trucks. Quote Link to comment https://www.bigmacktrucks.com/topic/38890-anybody-identify-this-rear-suspension/#findComment-278598 Share on other sites More sharing options...
storkmack Posted February 12, 2015 Share Posted February 12, 2015 What was the idea to flipping it over like that? Quote Link to comment https://www.bigmacktrucks.com/topic/38890-anybody-identify-this-rear-suspension/#findComment-278606 Share on other sites More sharing options...
james j neiweem Posted February 12, 2015 Share Posted February 12, 2015 Looks like it wouldn't be as stiff. Softer ride. Quote Link to comment https://www.bigmacktrucks.com/topic/38890-anybody-identify-this-rear-suspension/#findComment-278643 Share on other sites More sharing options...
j hancock Posted February 12, 2015 Share Posted February 12, 2015 My GUESS is that with the springs in the inverted style having less arch, there was more give and have a little bit better ride.

countryboy5487 Posted February 13, 2015 Share Posted February 13, 2015 Under slung suspension. Ya softer ride much like front leaf springs on a 90 ' s ford truck being bent over backwards Quote Link to comment https://www.bigmacktrucks.com/topic/38890-anybody-identify-this-rear-suspension/#findComment-278720 Share on other sites More sharing options...

57 bcr Posted February 13, 2015 Share Posted February 13, 2015 I think it was a little lighter (by how much?). Seems it was popular at the time with freight/tanker haulers.
