Solution for Raising Suspension of Trailer Instead of Going to Taller Suspension Equalizer
Question:
Im planning on replacing the equalizers and shackles on my 30foot 5th wheel trailer GVWR about 9700#. Can I replace my current EQ-356 equalizers with EQ-310 or EQ-103? This would give me about 1.5inch more lift which Id like if possible. Thanks.

I have a similar solution that would work if you are trying to gain height but going with a taller equalizer isn't the best option since the leaf spring would then be out of level as it would raise only one side of the axle.
You can do this by moving the axles from being above the leaf springs to below the leaf springs.
The diameter of your trailer axle will determine the size of the parts that you will need to order. If your axle is 3 inches diameter, the Dexter Trailer Springs Over-Under Conversion Kit, # K71-385-00, would be a great choice and if your axle is 2-3/8 inch diameter you could use the Over-Under Kit, # K71-384-00. These kits can be installed without welding but the manufacturer strongly recommends having the new spring seat tacked in place on the other side of the trailer axle.
Some refer to this process as "flipping the axles," but since axle has a slight bow to it you can't just flip them and reinstall them under the springs using the same spring seats. You have to install new spring seats on the opposite side of the axle so that it can be moved below the spring.
As long as your trailer matches the following three criteria an over-under kit would work well.
The trailer leaf spring stack is currently mounted under the axles
The trailer uses double-eye springs
And the trailer has 2-3/8 inch or 3 inch diameter round axles
If you cannot use an over/under conversion kit then the only other way to raise the height of the trailer is to have the old suspension hangers cut off and new, taller ones welded on by a qualified professional welder. I have included a link to the hanger main page for you.
