    Full Suspension Conversion on GX470
    We did a full suspension conversion on our 2006 Lexus GX470. The ride was becoming unbearable. It was like a bouncy house on wheels. We had our local mechanic install these and the Bilstein shocks. Worked great! Great ride. Maintained factory height. Mechanic did say he had to compress them a lot to get them in.
