The originals lasted about 50k miles of pretty hard use, so I can't be too mad at that. Shocks themselves are still in good shape, so we'll see how long the OE bushings last.I have done this, but on Tacomas as I lift a Tacoma almost every week. Common issue with 5100/6112. They fail more often than one would imagine. Definitely want to torque that lower shock bolt once tires are back on, vehicle on the ground.
