Suspension lift blocks on a multi axle suspension aren't recommended by Dexter axle mfg in my 1-800 to their tech line a few years back.
If you notice major axle mfg like Dexter...Rockwell American don't offer suspension blocks as a option on multi axle trailers nor do trailer mfg have a option for the blocks.
The sub frame lift is the best long term safest way to lift a trailer.
Those two pictures speaks volumes for the right way vs wrong way. Blocks just adds more stress to the U bolts.....top plates.....main frame rails...spring keepers...and spring hangers especially as the tires slide (side scrub) around corners and backing maneuvers.
Now if you have a single axle trailer then short blocks with upgrade diameter/longer U bolts...heavier top plates...and reinforced spring hanger brackets (braking rotational forces) would be a wise investment.
