Superduty HQ in AZ has a shop Raptor with the front perch mod and 37in Generals. I going with the truxxx leveling kit and the new Nittos when they are released. To my understanding there is some rub at full lock and the inner fender liner has to be removed.Yeah, snow covered grass is gonna be slippery and I don't think those tires are aggressive enough to handle it, no matter what special compound they are. I'd love to see someone with a leveling kit and 37" MT/R's on their Raptor
