Larger Isuzu 4WD trucks are fitted standard with a NoSpin differential. This particular unit is made under licence in Japan and the parts are not interchangeable with original U.S.A made units. The differences are in both design detail and metric versus inch dimensions.
Although individual components cannot be interchanged, Locked Drive Systems can supply complete, U.S made, replacement units.
Like all NoSpin centres, these fit into the original diff hemisphere case and are competitively priced, even against replacement components.
