I think one of us is misunderstanding the other.
The legs will extend the length of the ram. If you put a 4" block under it, it will raise 4" higher than it would have without. An 8" block will raise it 8" higher, 12" will raise it 12".
That's not engineering. It's math.

I hate this phone. I responded twice and lost both. If you put 8 inch blocks under my jacks on a level lot i would not be able to return the trailer to level once the truck was gone. The blocks dont change the travel available for the ram. If i put 6 inch blocks under the pads on a level site i can only drop the pins a couple holes and i will run out of verticle lift at the same time i would with 4 inch blacks and a 4 hole drop. At leastvthat is how i see it. Now for the real problem which was the jacks not lifting high enough to over come the downward movement of thr inflated trail air and the simulatenous upward of the unloaded truck springs. I tried raising the jacks this morning and they did nothing. I then used a couple bottle jacks to take the weight off the landing gear. They retracted normal and when i extended them they seemed to be working fine and raised the trailer nicely. So I have no idea whats going on. I have to leave in the morning so when my bride gets back from laundry ill hook up one way or the other. I am open for suggestions that do not involve bigger blocks. Thanks for the responses.

I didn't get a pic but it doesn't matter. I think I see why we come up with different answers about blocks. We are using different equipment. I note on your post above that your landing gear are solid. Because they are solid I agree that you can use a taller block to make the pin go higher.

My jacks are older style. They have an inner tube that can drop from 1 inch to about a max of ten to twelve inches and then be pinned to stay there. After I have set the drop where I want it and pinned the tube I extend the jacks. By adjusting that inner tube downward I am doing the same thing you are doing by putting blocks under solid jacks. Reducing the distance from the bottom of the retracted jacks to a hard surface.

When I park on a level site my trailer is almost level and it is about 10 to 12 inches from the jack pads to the ground. So I usually put down 4 inch blocks and 4 inches of drop on the inner tube. That has always left me with plenty of lift to clear the hitch. The 4 inch block plus the 4 inch drop is the same as an 8 inch block with solid jacks. Now, if I put down 8 inch blocks I can not adjust my inner tube down at all. I need to leave a couple inches of room to make a fine tune adjustment to level. OK. You with me? In the first case I have a 4 inch block plus 4 inch adjustment, or 8 inches plus the hydraulic lift. In the second case I have 8 inches of block and 0 inches of adjustment or 8 inches plus the hydraulic lift. If I chose to I could put down a 6 inch block and 2 inches of adjustment and I would have 8 inches plus the hydraulic lift. All of those would lift the pin box the same distance. On my equipment the taller blocks make no difference.

If you have no way to adjust your jacks then yes you would go higher with 8 inch blocks than with 4. I would not unless I choose to not use the inner tube adjustment but there is no logical reason to do that

UPDATE Yesterday the jacks would not lift the trailer. I had to lift the frame with a couple bottle jacks to take the weight off the landing gear. Once I did that I was able to retract the landing gear and then cycle it up and down a couple times. Then I put the blocks under and extended the jacks. They lifted the pin right up and I was able to hitch. Today I moved up to MI and when I unhitched I first ran the jacks up and down a couple times and then the jacks worked as designed.

I am thinking that one or more seals in the hydraulic tubes are starting to fail and that by cycling up and down the seals are either getting wetter or being pushed back in to position and that is allowing them to work intermittently. The other possibility is a valve failing. If that's the case I will need professional help. I should have had those landing gear rebuilt this summer but I put it off. If anyone has done the landing gear as a DIY project, how did you remove the drivers side tube. I'm thinking I will have to cut a hole in the sheet metal in the battery room. Help.

Well now, that's starting to make sense! I did not realize you had pin able jacks.

Bag to the air bag on the Trailair. The top of the arrows is a good starting point. My Redwood rides best when the shock is at the bottom of the arrow head. Trial and error will get you the best adjustment. For me, 75 psi puts it in the right place.
