I just installed one of these kits.Great value when bought online from Dexter. This Kit is very heavy duty and the new equalizer and shackle plates are much heavier than OEM. I did this just in time as the original dry plastic bushings were paper thin and just ready to cut through. I am an industrial mechanic but this is a job most handy guys could do themselves. I put the grease zerks on the inside as it is easier to grease from the inside.
