When i was putting in new air bags i had the bus raised and blocked and also used a piece of 4x4 between the bump stop and frame. During the night the wood split in two and one piece flew out and the other flipped sideways in place  and dropped the body a couple of inches. After that i took a piece of pipe and put a piece of metal on the top for the frame bumper to rest on, and put a piece about 1/2 to 3/4 inches up inside of the bottom of the pipe so it can sit on the bumper base and not slide off when the stop comes down on it.

If you cross the grain with multiple plys this won't happen, gluing is even better.

Also, solid oak blocks won't split usually. I made some from building post (that are still strong after 9 years) 4x4 by cutting them down a bit, 4" is too thick.

Oak will probably split under the right circumstances, but mine never did. It is tough as iron and was really hard on my saw blade! It may have been treated also.
