Just picked up a new NV 3500. Love this van and can't believe how well it handles and how easy it is to drive. I have test fit some new wheels and tires that I think will work great 20x9 +20 with 305/55/20. That being said I'm trying to find any info on compatibility for lift blocks or strut spacers. I've called advanced 4x4 in Utah because another member said they got strut spacers from them and they acted like they had no idea what I was talking about. They referred me to jackit and no luck there either. I'm looking for about 2" of lift. Searched everywhere with no luck. Thanks for any help!!
