Rear Springs

Re-arching is mostly a waste of time and money. The reason they went flat in the first place, is they were not up to the task to begin with. Quality replacement springs are the answer, or Timbrens. Air bags are adjustable, but have a finite life time under a MH.

As stated earlier call Henderson lineup. They can give you better information on springs.
Yes, they should have an arch.
I would get springs re-arched or replacements.

Of the two hunks of metal listed above, How much distance is there between the block, and the piece it is NOT attached to?

If no gap.. then your springs need help.

Another thing you can do is view the springs edge on

The springs a not broken, that I can tell that. I have worked on Trucks (18 wheelers) and I have seen both arched and flat springs. Most have an arch to them. But they do not use air bags or rubber blocks on the ones I have worked on 40 years ago. That is why I am asking, do the springs on a 1989 Chevy P-30/32 have a arch to them? What are the best way to go, Air Bag that gives 5000 lbs lift or rubber block (Timbren) that give 7000 lbs lift? I am hoping someone have real unbiased opinion on the two different types a lift accessed.

Thanks

All chassis have a spec for "ride height". This is what is used during front end alignment, etc. That is what needs to be checked before any changes are made to springs.

I would call these people. They are great on RV chassis issues.
The rear springs can loose some of the arc over time when rig is at vehicles max.
I ordered and had variable rate front springs installed that did away with the air bags. change really helped handling.

If your rig had standard air bags, I would fix them ASAP. The bags were intended to support some of the load, and they offer some adjustability that leaf springs will never ever give.

Fix the air bags. Put enuf pressure in them to level the coach. Try it out. Adjust pressure up or down for best ride and handling.

Note:

air or not, the spring rate (pounds per inch deflection) determines both the ride height and the comfort, that is the harshness or softness of the ride. Air bags do not automatically make a soft supple suspension. A properly sprung suspension, with the appropriate spring rate, and just the right shocks to control those springs, will give the best ride.

Had same feeling about my Pace Arrow. took it to a local Truck axle and springs shop, they rebuilt the leaf springs and added an extra leaf to each side the ride feel totally better now the cost was about $200
Their comment was an RV use a truck chassis and the original springs do not hold up to the extra,s added by the RV builders

I would like to know where you had yours done. The shop I talked to wanted about $2000.00 to do the same. He said RV offer some problems to access the springs.

Thanks

When I bought it (off the charity lot), it was on a flat lot and looked to be level. All Air Bags are shot, totally rotted away. I have only driven it a short distance and it seam to ride and handle OK. The RV needed some work before I can use it. I have looked at a 1986 Coachmen 30 foot and the spring looked to be the same. It too had no air bag, but I believe the Coachmen is lighter in weight. I am also needing to replace the bags. I have been looking at the Timbren SES for the rear. But I still haven't decided on air bags or the Timbren.

Thanks
