I was just wondering if I could go higher than 2.5 without getting adjusted control arms for the height increase by adding a 1.5 bottom strut spacer, but after adding the top 2.5 strut spacers I noticed the joints certainly did change...
I asked an ebay seller about their control arms and they mention they are good for a 2-4 inch lift but I'm not sure how I feel about that product...
My truck is 2wd and I think I might as well get lifted spindles as another member did to his suburban. The lifted spindles wouldn't increase the angle of the joints would they?
Since you are 2WD (that is why I asked) you do not have CVs, but still have other issues to address. IMO I still would not do the spacer on top and bottom of the strut. Jack it up, remove the tire and see for your self what/how other components are affected by just increasing the total strut length only. You need to have a proper lift > 2.5".
IMO at a minimum an upper control arm that can maintain the proper alignment (typically caster) and a uniball (instead of ball joint) to minimize binding at full articulation (uniball not so important in your case since you do not take the rig offroad); an extended spindle/knuckle to maintain the proper geometry between the UCA and LCA; and extended sway-bar links.
Do not get extended length UCAs. Those are associated with long travel kits and require more modifications like matching LCAs, extend brake lines, longer bumpstops, limit straps, etc.
