Thanks! The kit was used, and as far as I and the guy guy I purchased it from know (who also bought it slightly used) it's the Suburban 3/5. He had it on a Yukon and had the typical complaint of bad ride in back. It doesn't ride close to a factory burban, but it's not the worst lowered SUV I've been in, especially considering I'm on factory shocks with extenders in the rear.
The springs are the black and grey spatter looking ones. They're okay for now but I ultimately want to either go with air or the 6" spring. It's not ride quality that's the issue as much as ride height. I like Cali-lean and these aren't going to cut it. If the truck was paid for I would have dropped the money for the 3/5.5 or even the 4/6. I just couldn't pass on a $300 drop kit with helpers and shocks. With having the front installed and buying new balljoints and bushings I'm still at 60% of the price of a new kit. Tony, I'm glad there are people like you in this world, you go above and beyond to help even when it isn't your product beig used. Thank you.
