Fitment & Compatibility

For No Limit Engineering ZG spindles only, DS1542 requires removal of the two interfering spindle ears plus drilling and tapping two holes. Both spindles need the specified qualified machining before brake assembly. Check wheel stud location, bearing adjustment and the full 18-inch clearance diagram. The supplied hubs determine the available wheel patterns; the spindle itself is not included.
