Tony I have not played with anything yet. Want to get as much info as possible first. So you say the +35 would have pushed the tires in further. I looked here and online and most responses were that a +10 to +25 was the common range for wheels on the Yukon and when the rep suggested +18 I figured I was golden. It was really difficult to find any specs on 8.5x20's because most of you are running 22's and up. Its my understanding that the offset changes with wheel width so most would be in that 9-10" I have a mere 8.5. Anyway the keys are still set by the factory I had a look at them, there in or out halfway depending how you look at them LOL. I'm really working on a budget here as this is not what I strive for its a byproduct. I'm into Harleys . I own 3 and one race bike, so much time and money goes out the window elsewhere. I work as an auto tech so I do have much understanding of vehicles. I was gonna mark the bolt tonight and count the turns out to see where I'm at, then put it back once I know how far she comes down. The back I was really hoping to cut some coil with the whizzer, but those springs are bee hive. Ive heard of people using a torch to take some of the temper out of the spring. I dont even want to think about that. It sounds like a butch job, but I can maybe see it happen with them out of the truck with a spring compressor set to just the right amount this way the other side would be the same. also not concentrating the heat in one specific spot and near the bottom of the spring not top or center. My only concern would be breakage in time. Decisions decisions.
Mike your truck has a nice stance its not to radical just a clean truck. One concern I do have is alignment dropping this thing in the front I need to be able to get caster & camber back into adjustment. My alignment currently is perfect tires last me forever
