Lift blocks are never a good idea for a trailers leaf spring suspension on a multi axle trailer, vs a truck, for several reasons.
Notice axle makers nor the trailer makers offer them as OEM or a option on a leaf spring suspension.
The safest way is as Lincster says using a sub frame from steel structural tubing welded to the trailers main frame rails with heavy side plates with adjustable holes. Tubing size to be determined by how much the trailer needs to be raised.
I see one member went with 2" blocks on 5.2k axles with 5/8" diameter U bolts/heavier top plates and heavy custom made spring keepers.
Exactly why I did it the way I did.
Funny thing is, starting with the next model year trailers, Warrior started added that same component on all 5th wheels to clear 16" tires..... I wonder if I started a trend. LOL
