Anytime you raise a trailer or a truck, you decrease the stability due to a higher center of gravity (CG). The higher CG makes the vehicel tippy in plane terms, so you are always beeter off keeping the trailer or truck lower than higher. As for the axles over or under the springs, aand the use of dropped axles over staight axles, it is all done to keep the CG lower. With the taller tow vehicles, you se more and moer trailer that set high...but if you notice, the olser trailers like the SS all tow better with fewer problems than the current trailer. Part of the reason for towing better is the aerodynamics and part is the lower CG. By going from an over spring to an under spring arrangement, is a minimal lift and probably will not be noticed on a properly matched tow vehicle.

B You can bet he did not do the axle flip on the second S/S. There is only so much movement (rocking) that, first, the shock absorbers and, second, the springs can handle when the trailer starts to tip for whatever reason. B The design of the suspension needs to be different to accommodate this increased height. -----Original Message----- From: Bussiere, Curtis L SFC RES USAR TRADOC <curtis.bussiere@us.army.mil> To: sslist <sslist@tompatterson.com> Sent: Mon, 21 Apr 2008 5:51 am Subject: [SilverStreak] Flipped axels (again) I am trying to post pictures of my 1974 Continental Supreme. Last summer I flipped the axels and installed new shocks in order to give the unit more ground clearance and present a better appearance when hooked up to a more modern higher tow vehicle. At that time there was much discussion about center of balance and some speculated that the additional 4 inches would make the rig a tipping hazard. This has proven to not be the case with us. We have put several hundred miles on since the flip and if anything it seems to handle better. It required new center pins and guide holes and of course anytime I remove a U bolt I replace it. The old shocks were a couple of inches to short and the boys at Auto Zone let me go back and dig through their shocks to find the size I needed. Of course all was torqued then routinely checked along the road for the first hundred miles as new U bolts will stretch. There has been no slipping and the axels track is true. This was a driveway project and I recommend it to anyone who wants to stop dragging their tail over every dip and improve the look of their unit when towing with a higher clearance vehicle. I will await directions for posting my pictures. This was not a 180deg flip it was moving the axels from top to the bottom of the springs. a 180deg flip will not work as the axels are designed to flex one way only. (dot ask me how I know this) Thanks Curt
