bigmacksuperliner89 Posted August 10, 2005 Share Posted August 10, 2005 I went to look at some Superliners today and one of the trucks was an RW613 and the frame was a lot smaller in height than the other trucks that I looked at. I think the other trucks were RW713's but I forgot to look. Is there a frame height difference between an RW613 and an RW713? Thanks in advance,Scott Quote Link to comment Share on other sites More sharing options...
Lmackattack Posted August 10, 2005 Share Posted August 10, 2005 not shure??? did the trucks have air ride? maybee the air bags were down??? Quote Link to comment Share on other sites More sharing options...
87valueliner Posted August 10, 2005 Share Posted August 10, 2005 There are some different frame sizes in Macks. The smaller frame is probably the standard R- model frame. The taller, wider frame is probably the RD frame. As far as a difference between Superliners, I don't know. Go to the old boards and look under my old name 87RS688lst as I asked a similar question not long ago, might have some info to help.

David Posted August 10, 2005 Share Posted August 10, 2005 The difference between a RW6__ and RW7__ is the frame. The RW6 cross section is 13.1"x 3.3"x .24" and unloaded height is 38.6". The RW7 cross section is 13.5"x 3.4"x.39" and unloaded height is 39.7 to 40.4". This is from a spec book dated oct. 1990. Hope this helps.....David Quote Link to comment Share on other sites More sharing options...
bigmacksuperliner89 Posted August 10, 2005 Author Share Posted August 10, 2005 Thanks everyone for the help. The RW613 was the truck I liked the most out of all of them I looked at. Now I gotta hunt the guy down and try to buy one of the trucks or maybe two if they are cheap. Then I can post some pictures of it.
