Re: 2007 Jayco Seneca 34SS Suspension upgrades Reply #4 – July 23, 2012, 09:14:29 pm Yahoo Message Number: 9527I know some members added an extra leaf or air bags. There were some chassis that only had 15,000 lb rear springs. Hopefully one of them will "chime" in soon.

Re: 2007 Jayco Seneca 34SS Suspension upgrades Reply #6 – July 23, 2012, 09:52:26 pm Yahoo Message Number: 9529Don, my 2007 Jayco Kodiak Greyhawk was on a 2007 chassis. The 2007 announcement by GM included the fact that they went to the six speed transmission as well as of 2007. We had the 6.Early Greyhawk gassers were on the 2006 and had the 5 speed. I think early 2007 Senecas were on the 2006 as if my memory is working.I think Gary should look at the codes on the visor and also look at the chassis build year to establish what he has and which options are on his specific unit.MTR means you have the 6 speed close ratio Allison.GQ0 indicates 15,000 lb tapered leaf springsGN2 indicates 19,000 lb tapered leaf springs.The 2007 order forms are in the files section and you can see all the codes.Don Quote Selected

I got them for our Kodiak and our toad (2007 Tahoe LTZ) and they were very helpful.Gary, if you want to see what they are before you sign up and request one let me know and I'll send you mine.
