Aluminum trailer/leaf spring wear

[Capt Terry]

In Fla trips to the ramps were short, but the last 20 years in SC the trips are 90 RT. I thought the clearance between my trailer tires and fenders was less than it used to be on my 40 year old tandem axle Hitchhiker trailer. The leaf springs were replaced just before leaving Fla and they were only dunked in salt water once when the Seafari was loaded for the move north. Therefore the springs themselves look great. The springs are captured in a c-channel (inverted like the letter “n”). I noticed where the aft end (camel hump end) of the leaf springs contacts the aluminum it was worn perhaps .25”. I think my solution will be to insert some bolted in, aluminum spacers between the hump and the c-channel to restore it to near the original position. So the point of this message is to see if:
1- Anyone had developed a better solution for this issue
2- Alert others using steel springs in contact with aluminum trailers about potential wear
