I still need to do some more brake bleeding, adjust the toe-in, and mount the steering damper, but I took her for a spin anyway...
Huge improvement! The heavy springs are pretty firm, but not as stiff as the leafs. It feels good for the 60 though, since it still feels like a truck. With a load, it should ride like a caddy. Medium springs might be a better fit for DD duty, but this is still better than the leaf springs.
These shocks are $$$. I went through a neighborhood with gently sloped speed bumps and flew through it at full speed. I found some tall, sharp speed bumps in a parking lot and it is much better than before.
Bumps at speed, like potholes and poorly leveled manhole covers are a joke. You start aiming for them because it feels good to hit them. It just soaks them up. It's much quieter over bumps too since it's not as much of a shock to the system.
Between the heavy springs, these shocks, the extra width, and the front & rear swaybars, it corners like a racecar. Ok, maybe not, but even with the extra height, it doesn't feel any less stable than before. Maybe more so.
Steering is squirrelly. The toe is off for starters, but it does need some caster correction. Mark put some caster plates on his truck today and said it made a huge improvement, I'll do the same soon. Effort at the wheel is much less. This 80 box is nice.
I'll try and tighten up the loose ends tomorrow and maybe flex 'er out.
