Just an FYI on the subject:
Eaton Spring carries a leaf spring liner product made of Delrin (Dupont
trade name for acetal homoplymer).. There is a never ending debate re: which
is tougher and lower in friction, Delrin or UHMW. I bought the Eaton
product for my TR3A springs and will install the new packages this winter.
The
material is ~0.045 - 0.050" thick, and 2" wide with raised lips at the edges
to keep the strips aligned with the spring leaves. I believe the material
is extruded. Off roader's apparently are big fans of the stuff.
The material is pretty hefty so I was a little worried that the installed
total thickness would not allow me to reclamp the spring package; it was
tight but things did go together. As I said above, no experience on the road
yet.
