    Comments about Slipper Leaf Springs:

    These were exactly what I needed for our sailboat trailer. The 30" slipper size was impossible to find in any local store so I had to have WM ship them. My only complaint is that for our installation, I needed to reverse the center lug to fit our trailer (they arrived with the lug facing up for below axle mounting, our trailer needs the opposite) but when I attempted to unscrew the lug, I found the threads stripped and ended up damaging them beyond repair by removing them. I then had to manufacture a new lug myself as I did not want to wait weeks to return them for an exchange. This was an unnecessary hassle because some person at the factory overtightened them. Otherwise, I am pleased with the springs. Decent price and they serve my purposes.
