actually not much wheel hop....to much spin :/, but when the wheels are under torque the tires want to turn forwad which causes the axel to want to turn backwards, now with 8" leverage from the wheels to springs is going to cause windup and cause your pinion to turn upwards thuse the springs have to absorb that twist upwards, now its not the springs to worry about its the ubolts holding everything together you have to worry about, ive seen ubolts snap from torque and weight preventing wheel slippage, a trailer on the other hand is alot different, the axels are being drug but the truck thus they want to twist forward, with blocks the twist will increase causing your equlizer linkage to want to twist causing the back of the front spring to go up and the front of the back springs to go down, but at the same time you have 3000lbs holding the springs strait  the suspension itself will handle the blocks and twist, thats what its designed for, now as long as you dont plan on sinking it in the mud or skag and drag it through all should be well, the top heavy on the other hand is more of an issue but with the 5er holding it from swaying should be fine.  now the other part of blocks is when the suspension "walks" the axels will do a caster motion much like your steering axel (axel tips forward and back) and depending on the camber angle (tire lean in and out at the top) of the trailer might cause premature tire wear due to change in angles while walking, but if the trailer tows level none of that should matter.
