SB Chevy Aluminum Crankshaft Hub
ALL90030
Designed specifically for circle track racers,
this SB Chevy aluminum crank hub is NOT a
harmonic damper. Hub is significantly lighter than
a harmonic balancer and dramatically reduces
rotating weight for quicker acceleration off the
turn. Hub has engraved timing marks at 0° and
from 30°-42°, is 4-3/8" in dia., features (3) 3/8"-16
accessory threads and weighs just one pound. Fits all
internally balanced small block Chevy engines. Designed
for internally balanced engines only and must be balanced with rotating assembly.
Weld Bungs
Weld-on bungs are available in 6061 aluminum or mild steel and allow additional fittings to be added to radiators, oil pans, building of custom tanks or other components.
