Lifting Trailer Options and Recommendations
Question:
why cant you use 2inch spacer blocks between your axel and spring on a 5th wheel tandem trailer

Expert Reply:
Some people will use spacer blocks to lift a trailer if the springs are over the axle. We don't typically recommend that though. We usually recommend either going with an over-under axle kit or going with taller hangers.
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.
If you do think raising the trailer in the back is the way to go then you may be able to use an over/under conversion kit if:
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.
