HI Gene;
Yes, I"ve looked at all of that material over time;
The Sullybilt isn't on the comparison table, and I may have missed it, but don't see a measurement or statement regarding suspension travel.
My instinct says that travel will likely be reduced with this system, but would obviously defer to a source that has actually measured it or has some evidence to the contrary.
The quadrabag systems look neat, but my personal taste is to keep the 'walking,' function of the bogies as I think it adds quite a measure of smoothness to the ride.
If I want to corner like a demon, I'll get into a sports car. I don't need to do that in my coach.
Just this redeck's priorities. Other may vary.
Scott.

Hi Scott
Here is a quote from a previous message from Sully
>The Sullybilt kit operates at much lower pressure than oem or four bag systems. All who have
>purchased my system report same or better ride quality than oem. Lower operating pressure
>reduces load on the compressor/s which should extend compressor life. Overall operating range
>is reduced by 3/4" over stock. Max lift is reduced by 1/4" due to travel range of the bag and max
>lowering is reduced by 1/2" due to the bags internal bump stop. With a completely deflated or
>torn bag the coach can still be driven without rubbing through the wheel well ( a good thing I
>think)

I have a sully bag system installed. very well built - easy to install.
Not a whole lot of miles, on it, but lots of leveling. The spreadsheet says 1/2" of difference from stock across the whole range - I don't notice the diference.
YMMV

Thanks for posting my quote Dave. The measurement was taken from the grease gun fitting on the bogie pins to a concrete floor. Measurements were taken on one side several times and measured from a paint stick spanning the grease fittings.
I also recorded inflation and deflation times. These times are only for comparison between oem and Sullybilt as nothin else had been altered at time of the test. Info was written down in my file which I haven't looked at in years. I do remember that time to set ride height was much quicker with the Sullybilt than oem. Time to max lift fairly comparable as the point of diminishing returns hits with both systems at the end of the lift range.
Sorry for the late reply but I am currently on a gmc vacation in SoCal.

Right now I use two inexpensive tire inflator compressors ($79 each) instead of stock or the more expensive Viair stuff. Fast fill-up. Little strain.

No larger air compressor is required. 90 pounds of pressure is still 90 pounds of pressure. Different compressors just deliver at different rates. Rates relate to time to desired pressure.
Yes, many of the Dana's are a little tired, but they can still do the job.
Frankly, the Valair compressors are very nice, as well as the Thomas brand. You pays your money and take your choices.

I have had the Sullybilt system for about a year and have only driven about 2000 miles since installation. I purchased it with a lot of apprehension. I was torn between the Quad bag and Sullybilt. I spoke with Todd on the phone a couple of times and with some reassurance I finally decided to go with his system based on the price difference. Seldom does going with the lower priced item turn out well for the purchaser. I am happy to report that this product does not follow that rule. I have been incredibly happy with this system. It runs at much lower pressures, rides and handles great and it takes some of the harshness out of hitting potholes(which we have a lot of in South Dakota). This is not a comparison or an insult to any other aftermarket system it is just my experience, for what its worth.

Indeed. I think the quad systems are a lustworthy piece of engineering.
On a ground up budget, I might spec a quad bag. Its definitely on a wish list. On a "what-is-it-this-time?" budget, I'd spend what I need to get mobile and brace for the next surprise.
And then, some folks prefer to spend the budget on paint, or engine, or transmission or all of the above. Luckily, this system seems to be a quality alternative.

With luck we are heading to Yellowstone in June. The plan is for something like 6k-8k miles by the time we return. I'll give you a critique of the Sully single bag system after that, but I do believe it will be the same story as the Eagle Forged wheels....save enough on the wheels to pay for the tires and save enough on the air bags to pay for the kitchen overhaul with new stove, undermount sink, faucet, granite and drawer and transmission oil cooler and lines.....and see ZERO difference in the performance between those and the higher priced parts.
|
We have had the Sully system on for 2 yrs now and have about 14K miles on them. We have experienced no perceptible difference in ride. For me, the bags seem to air up faster when used for site leveling. We run 40-45 lbs of pressure down the road. On the down side it seems that I have lost 1/2 to 3/4" in total height when raised to full up. But then I'm using Airtech bags instead of the recommended Firestones....(My Bad).
IMO, a really good choice for replacement of rear suspension.
