Kodiak Chassis Upgrades July 10, 2007, 04:16:49 am Yahoo Message Number: 11Just joined this forum after finding a link on RV.NET.Hope it gets going good.We have a 2004 Gulf Stream Endura 6340 D/A. Purchased it in April 2006. Have put 18,000 miles on it since then. Very happy with our purchase. MPG is at 10.3 for the miles we have had MH. Some problems but have taken care of them on my own. No GS warranty, bought used over 1 year old. Did have some GM warranty repairs done at a MD truck dealership. Great service.Attended a Gulf Stream Rally in Goshen, IN. last month. One of the vendors at the rally wasMcCormick Motors | Nappanee, IN | McCormick Motors.They supply the C5500 chassis for all the manufactures in north IN. They have a couple of kits that help C5500 handle better. One is Stabil Ride. Which is a larger anti-sway bar for the front and longer over travel snubber for the rear. A second kit includes Stable Ride and Bilstien shocks. I have purchased and installed these items on my 2004 Endura 6340. Has made a big difference in the rocking that occurs at slow speeds when making turns.Gulf Stream has Stabil Ride installed on all C5500 that they get on 2005 and newer models. Jayco only puts it on Gas models. Do not know what other manufactures use. I had already installed Bilstien shocks on the MH. Cost was less than $500 with me installing the parts.My C5500 is a 19,500 lbs Chassis. Rear shocks on the 22,500 are different than the lower weight MH. Make sure if you get these parts that you specify the chassis weight. Can get part #'s for anyone that is interested. I talked to Ivy Arndt at McCormick for this information.
