Need 3 inches of height!

We have a 77 airstream sovereign that we completely gutted and rebuilt. We installed bigger waste tanks that caused the drain pipe to have to be about 4 inches lower then it was before - now we have the release valves coming up through the bumper instead of through the back compartment. We used a drop hitch to get it to toe level but it still hits the drain pipe when we go over bumps and hills. We replaced the axels but not the leaf springs. Would installing new leaf springs give us about 3 more inches? Or any other suggestions?

A 1977 doesn't have leaf springs. It has rubber torsion springs inside the axle assembly.

That is a tall order to raise it by 3 inches.

And there may be users that have suggestions.

Mine wold be taller tires and that will only get part of your 3".

Your trailer doesn't have leaf springs. All Airstream's built after 1960 used rubber torsion axles. The torsion arms were all preset at the factory at 22.5 degrees (except for a few late model small Sport models that have 10 degree arms). Most of my clients request the original torsion angle, however there are a few who want a little more clearance. In this instance we order axles with 32 degree torsion arms, which gives 1 1/2" - 2" greater ground clearance than original.
