Been considering this to get a 1" drop to keep my truck from sitting bulldog once I install 2" rear shackles.

I found some specs on MOOG replacement springs.

CC648:
bar diameter .87
15.25" free height
4.05" ID
12.75" installed height
2300lb load rate
870lb/inch

CC650
.90
15" free height
4.08" ID
12.75" installed height
2325 lb load rate
1025 lb/inch

CC650S
.90
15.44" free height
4.08" ID
13" installed height
2669 lb load
1090lb/inch

60148
.81
4.23 ID
16.63" free height
13" installed height
2684 lb load rate
742lb/inch

Which set would suit me best? I'm leaning towards the CC648. I'd prefer to avoid cutting coils off, or stiffer lowering coils.
