I'm wanting to know if anyone knows where I could get a conversion kit that replaces the Nivomat self leveling shocks to a normal gas shock. I have read that with other models of 's when doing this conversion the spring has to be upgraded as well. I'v searched high and low, and I can't find a kit for the XC90. Is there another model that shares the same shock and strut package???? 2004 / XC90 / 2.5T / FWD
