Question:

Could air bags / air ride be used to raise the ride height? I have a new 2014 36foot 8foot Puma Toy Hauler. Every thing said and dun and having the clearance between the truck box and the trailer where it needs to be I still need 3 to 4 more inches lift in the rear of the trailer. This would give me a perfect level ride on the highway and another few inches of clearance at the rear of the trailer. Welding on the frame is not an option because of the totally enclosed underbelly. This would wind up costing more than it would be worth I think. Thanks for any ideas that would work well and be safe to use.

I have a solution that could work for you, but we do not sell air kits for trailer suspension to raise the ride height.

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.

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.
