leversole Posted December 28, 2011 Share Posted December 28, 2011 What are the main differences between the RW6's and RW7's? And within the series, as the numbers go up does that mean more heavy duty?Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/22349-superliner-models/ Share on other sites More sharing options...

David Posted December 28, 2011 Share Posted December 28, 2011 The RW6xx has 1/4" rails and the RW7xx has 3/8". Both had a second member option. Quote Link to comment https://www.bigmacktrucks.com/topic/22349-superliner-models/#findComment-95710 Share on other sites More sharing options...

David Posted December 28, 2011 Share Posted December 28, 2011 The RW6xx has 1/4" rails and the RW7xx has 3/8". Both had a second member option.This applies to the Superliner II. I don't know if there was a RW7xx for the early models.

Superdog Posted December 28, 2011 Share Posted December 28, 2011 This applies to the Superliner II. I don't know if there was a RW7xx for the early models.The early Superliners were all RW7xx models.They were RWS7xx for the steel frame and RWL7xx for the aluminum frame.

shortstack Posted December 29, 2011 Share Posted December 29, 2011 What's the easiest way to tell a Superliner I from a II just at a glance? Is that when they went to square headlights or are there other ways to tell?

Rob Posted December 29, 2011 Share Posted December 29, 2011 The hood for certain but the frame, and the steering gear mounting was different. The Superliner 1 used a steering axle mounted steering gear. The Superliner II used a frame mounted steering gear along with rectangular headlamps.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

David Posted December 29, 2011 Share Posted December 29, 2011 The holes in the bumper are very different because of the tow pins located in the spring hangers on the Superliner II.

shortstack Posted December 29, 2011 Share Posted December 29, 2011 What is it about the hood that's different? I was wondering if you couldn't get real close to one other than the headlights if there was a way to tell them apart.

The holes in the bumpers for the tow hooks are different enough that you can tell from a distance.

shortstack Posted December 30, 2011 Share Posted December 30, 2011 Okay thanks! I'm guessing since the frame is wider they are just further apart? Quote Link to comment https://www.bigmacktrucks.com/topic/22349-superliner-models/#findComment-95940 Share on other sites More sharing options...
David Posted December 30, 2011 Share Posted December 30, 2011 The second picture is Superliner II headlights and a Superliner I bumper. Quote Link to comment https://www.bigmacktrucks.com/topic/22349-superliner-models/#findComment-95957 Share on other sites More sharing options...
David Posted December 30, 2011 Share Posted December 30, 2011 The "Deep" or "Extended" bumper on the Superliner II is the exception. It covers the tow pin on the front of the spring hanger.

shortstack Posted December 30, 2011 Share Posted December 30, 2011 Thanks David. I can see the difference now and I sure enjoyed seeing more pictures!
