I have a new Kraton I bought a month or so ago . It is the V2. How important is it to shim its diffs ? I changed the center diff fluid to 100k and that's the extent of what I've done to it. I'm installing the orange springs (front and rear) this week. I've run it over grass(6s) a few times and that's about it. Please keep your responses to personal experience only. Your opinion is just that w/o actual experience with this exact truck. Not trying to be offensive at all I just want accurate info. Thanks
