The Naake’s Marauder kit comes with just the shocks and springs—you can either reuse your original spring mounts and isolators or buy new ones like I did. I bought new mounts (half visible on the right side of the frame) from South Bay Ford, just down the street from our office. The isolators actually consist of the rubber piece I’m holding and the hard plastic ramp underneath it. Shop around for those. The dealer price was more than $100 each, but I purchased them online for about $80 apiece. If you want to reuse your stock spring mounts and isolators, you will need to hold the spring in a compressor to loosen the top bolt. It feels like there is still a substantial amount of pressure on the spring even out of the car. With 160,000 miles on my car, I felt it was worth the money to change these parts.
