Correct SumoSprings for Keystone Passport Elite Travel Trailer 4,400 Lb Axles

Question:

What Sumospring kit do I need? I have 5 15/16 inches from the frame rail to the top of the spring hold down plate. Axle is under spring. Thanks for any help.

The correct SumoSprings Trailer Helper Springs for overslung axles (axle under leaf springs) is part # TSS-107-40. The springs will be pre-loaded upon installation therefore the space you have between the frame is spring loaded will be less than the height of the spring and bracket. This won't be an issue.
