V8 Features:

Each bob-weight half is a precise weight so bob-weights can be weighed one half at a time.

Graduated slip nuts allow fast assembly and precise adjustment without using calipers to check the gaps.  Bob-weights also have reference marks to show which nuts go on which stud and which direction to turn the halves.

Extra Shims Available for Bob-weights!

V8 shim type weights make it fast and easy to set up each bob-weight.
Bolts of different lengths are provided for shim type weights.
