Thanks guys. I took my truck to a local off road shop, and that is what they recommended, and also what they carried in stock. I looked as well, iirc they only listed 2 1/4"? It has two spacers top and bottom. Sits perfectly level. Great ride, no significant difference than the stock ride quality.
Yes. +18 offset. With those tires, it's the perfect setup for my purposes. No rubbing, trimming, etc... You can always go bigger, but this is perfect for daily use.
