I'm Awesome
so my question is how would a drop leaf with the hanger-shackle combo ride...and keep in mind i'm 40 and don't need the firm sport truck ride any more
The shackles and hangers don't change your truck's ride any. All they do is relocate the leaf spring higher into the body, but your ride will be the same since you're using the stock leaf springs. If you have drop shocks your damping rates will change, but not your spring rates.
Drop leafs are a little softer and somewhat bouncier than stock leaf springs, but not in a bad way. I had a 5/8 on my '91 and drove it that way for a good 100,000 miles. I used shackles, hangers and 4" leafs in the rear to get the 8". I liked the setup. It rode and handled extremely well.
...and whether i should use spindles up front or get the upper and lower control arms...I know what i'm getting with spindles, I guess I just really like the idea of brand new upper and lower control arms and wonder what other than the lca being closer to the ground are the negatives of that set up?
If you're wanting a 4/6, then you're going to have to combine your spindles or control arms with drop coils as well. Since this is the case, I would recommend sticking with spindles. Running drop arms with drop springs is a recipe for balljoint failure. I ran 3" arms with 2" coils on my truck. I replaced my lower balljoints once, but I count myself lucky that I never had a failure. I know several other guys who ran the same setup and all had a balljoint failure at some point. Spindles and springs is a tried and true setup with the best reliability.
