Ruuing a higher ride highth then normal.

[Bob Dunahugh]

I need to run the rear frame height about 1 to 2 inches above the factory spec. I have the quad bag system. This system seems to be more stable. But also a little more course. Over all I'm very please with it's performance. But when you run above stock at the rear. You start to reduce your front negative caster. And we already have very little negative caster to start with. So I need to raise the front to match the rear extra height. So are there others that have done this?

Bob, are you running some of Lenzi upper control arms? Should be able to get several more degrees and still keep your cv joints running in their
sweet spot.

Bob,

Not on purpose, but my front height seems about 1" too high. Dave Lenzi tried helping drop it with me, but it was determined it could not go down
without re-indexing the pork chops, so we just made it even side to side, and I run the rear just a little lower then the front.

I am not a good example as to if it drives good or bad. But I drive it fine with one hand, and my wife does not seem to ever tell me that it
handles terrible. There is quite a few parts in my front, that has never been replaced.

so just a thought, I would not think you would notice that much difference, as long as the front is slightly higher then the rear.

I have in the past aired up the rear bags to level the coach and locked
them out at the schraders. I have forgotten several times to open the
schraders when preparing to depart. Rather than feeling the handling
difference then stopping to correct I many times drove for extended periods
with the coach level or slightly higher in the rear and the coach drove
fine.

John,

IIRC with the front end set at the correct OEM ride height the axles are parallel to the ground (or damn near). When Bob raises the
front end both the upper and lower control arms will be higher where they connect to the frame than at the ball joints. They will be
pitched downwards as one looks at them from the front. The inner CV joint will be higher than the outer CV joint and the axles will
be angled down. I agree with you that it probably will be OK.

As far as Dave's offset upper control arms go when I put them on Double Trouble caster went from 1.9° to 4.9°!

Having said all this if Bob raises the front ride height 2 inches and the rear ride height 2 inches they will both be in the same
position relative to each other - I THINK.

Regards,
Rob M.

Bob.
I inadvertently ran my ride about a inch too high in the past. It drove fine, but what John sharpe said, it angeled the cv joints in the front axel
out of their sweet spot. My only damaged was to the inner cv boot, which means grease all over the place at highway speed.
So 2 new axels later. .....
