Does anyone know where I can buy a 6 inch suspension lift kit for a 2000

[Drew M]

cadillac escalade? I've searched the internet for hours but can only find 3 inch lift kits. I want to know if anyone knows where I can find a 6 inch lift kit for it. Are there any other vehicles with similar suspensions that i can buy and put on my escalade? And also how much does it usually cost to have them put on? Thank you
