There are planty of things that can be done..some of them sound engineering and other plain rough and butcherous.
Any type of axle spacer is rough and butcherous, and very much frowned upon by regulators in all states in all types of vehicles....like wise extended spring shackles.
If it is a plain spring and beam axle
suspension it is possible on trailers to "spring over" the
suspension....that is place the axle under
the springs rather than over them.
Two of my three trailers are sprung over and have been since new, one of my boat trailers comes sprung under when fitted with 13 inch rims, if optioned with 14 inch rims it comes sprung over.
This will pick up arround 2 inches of chasis height...and its costs very little
another non butcherous thing is to increase the size of the wheels or tyres.
BUT....most axles are designed arround a specific wheel size...so an axle designed for 14 inch or less pasenger car wheels will have to be derated to carry 15 inch or 16 inch 4wd wheels and tyres...or a different axle fitted.
Moving from 13 inch rims to 14 inch rims will gain a few inches of height..if you have the clearance from the body work.....14 inch rims will also get you a better selection of tyres.
springing over and going from 13 to 14 inch rims, could yeild a good 4 inches....a relativly cheap mod...seen it done on those older style light camper trailers.
You could fit drop axles...but they present some engineering issues.
a better choice would be to have the
suspension mounts lifted.
There have been plenty of vans rejigged by installing very much taller suspenion under the existing chasis...or a complete chasis under the existing
AND, remember if you are increasing the chasis heaight the coupling needs to be corrected too so the trailer travels level or close to it.
NOW as for the legalities...ahh
well......the regs for trailers can be a bit vague....and there is a bit of a who cares attitude........official or not...and..there are certain things that are permitted or allowed that would not be for cars and trucks.
IF you have a later model trailer with a vin plate and tyre plackard....hmm you may have to get that...engineered.
Oh remember too the effects of increasing the centre of gravity.
If ya lifting the
suspension it may be wise to add some shockies or otherwise improve the stability.
