I also wanted to raise the front to level it with the back and what I found out after reading about the procedure was that a 3″ lift will affect the geometry adversely. As it is, the suspension has to be disassembled to install the riser puck on top of the spring and shock assembly. The steering alignment will need to be reset and the headlights re-aimed lower. The riser is fairly cheap to buy (about $50) it’s the installation and alignment that run anywhere from $300 to above $500 unless you can do it yourself. Still need the proper alignment performed. The materials they’re made from will determine their longevity. I’d stay away from the plastic ones unless you really enjoy replacing them.
