    Didn't the rear leaf springs on Blazers come with full length anti-friction inserts (teflon?) starting in '89?
    I've taken the rear spring pack apart to get rid of the rust (belt sander + POR15=real fun); on my '85, the inserts were at the ends only and in the middle between the overload leaf and the next leaf. I thought I might replace the inserts when I put the pack together; could I use the full-length stuff from the later years? thanks, michael

    I'm not sure what the factory did on trucks but I'm planning on getting a roll of UHMW Polyethylene Tape to put between my leaves next time I have them apart.

    It's actually pretty cheap stuff. You can buy it on-line at http://www.mcmaster.com/ or from some spring shops.

    Ultra High Molecular Weight (UHMW) Polyethylene is usually used in factories and packaging plants to provide a nice gliding surface for packages. Folks have been sandwiching this stuff between their leaves for a better ride on everything from Land-Rovers to farm tractors and most seem to be happy with the results.

    I started looking into this stuff when I saw <font color="orange"> jekbrown's </font>writeup of his axle swap. He was able to buy the stuff at a local plastics shop.

    mine is 0.060... but the 30 stuff is just as good and its cheaper to. the ONLY reason I went 060 is because the place i got mine from didnt have the 030 stuff in-stock that day and I was in a hurry. /forums/images/graemlins/grin.gif
