I also did the 3.5 inch Clayton Overland Plus exactly to spec. I ended up with 5.8 to 6.0 of caster. After about 3 months or so, I lengthen my lowers by 1/2 turn and shortened by uppers 1/2 turn to get a little more caster up front. That is perfect for me. It gave me a little more stability at high speed fwy driving.Installed lift last night to Clayton's specs for everything. Was wondering how close their measurements kept everything in spec? Caster and pinion angles?
Going to get aligned today this is just personal edification.
