so they are thicker then the shackles id have on my truck? is that what your saying?

its a c&c
axle code is 65 which is a 10.25 4.10 open with gvw of 8200
wb is 137
t19
f384
body is dd8?
gvwr is 11k lol

body is nice but i really liked my 354...even with the 36 tires it had plenty of power and the rebuilt motor should give me better gas mileage then before( ten with bad feedback carb)
will the 4.10 be okay with a zf5 on a 70 mpg highway with a 300 six?
