better ride?

Anyone figured out how to get a softer ride with there bus and not having to spend thousands of dollars?, I weighed my bus and lowered the tire pressure, that helped a bit, I've been reading up on koni shocks lots of good reviews about them, suppose to really improve ride, but not really sure it would do any good with a bus suspension. Putting in a air ride would be nice, but way to much $$ for me. Any ideals on this?

School buses all seem to have notoriously stiff springs and little if any in the way of shocks.

You can remove a few spring leafs but it can be tricky to balance softness against bounce. If you do remove a few leafs, stiffer shocks will help. Other than that, replacing them with less stiff leaves or air bags are among few choices. Personally, I have never been a fan of air bag rides. They all seem to "wallow" around too much for me.

I replaced all my springs with new ones from Eaton Detroit...very knowledgeable folks. I reduced the rating on the rear by 50% and added another 350 lbs. to the front (to compensate for the weight of the diesel engine). Also added modern shocks all around. Yet to drive it still, but I am prepared to add or subtract more as needed.

Anyone else have any thoughts

On bigger school buses, broken springs seem to be an issue, so I'd hesitate to remove any.
That said- I have one air spring on its way out.

I would also try removing a few leafs.

At the shop, we remove the older packs with up to 10 thin leafs in them, and replace them with thicker 3 leaf units.

Much better ride.

Removing leafs will not cause broken leafs. Bad bumps, wheel hops, time, ect are what causes broken springs.

If full air ride is to costly, you can still add helper bags like they do on pickup trucks after removing the unneeded leafs from the pack. That way you can pump them up when full of water, fuel, ect.

I would bring it to a real spring shop, instead of guessing what the outcome of removing leafs would be. Tell them what you want and have them build you some springs...new. Problem solved correctly.

I changed my leafs over to Air rides. not a easy job and you have to add the compressor and tanks but in the end the ride quality was so much better it was worth it, and the money i saved from having to replace things that bounced out of cabinets we took another trip.

I bought a donor bus same year make and model as my bus even the same engine and trans the difference was it had air brakes and air rides where i have hydraulic and springs. parked them side by side and jacked them up and swapped the air rides to mine spring to donor and the compressor and tank. sold donor bus for more than i paid for it to a friend that wanted a new project. he did have to replace the compressor and tank for his brakes but that was cheap at a truck junk yard.

I think a visit to a spring shop will be in my future, I have been reading great things about koni shocks for motor homes, but I don't know how well they will change the ride with those big leaf springs. I will do more research about them.
