Just wanted to say that I am very impressed with the MPI Oilite bushings. Last night, I installed them in my XTX front end. I recently bought the sled and found nearly new OEM bushings upon removal. However, the comparison was immediately evident. When lifting the spindle with the OEM bushings, the entire thing would settle back down. With the oilite bushings, the spindle stays put.
Also, I would like to say by far the easiest way to install them is with 1/2" threaded rod, a couple larger washers and nuts. Do one at a time. Tighten one side up against the arm and then "press" the bushing in by tightening the nut against the new bushing.
