A spindle assembly, a bare housing and a replacement shaft are different purchases. Check what is supplied before comparing prices, then match the mounting pattern and shaft interface to the deck documentation.
Check each listing for the supplied components. A housing, shaft or bearing is not the same purchase as a complete spindle assembly; confirm any pulley and hardware inclusion separately.
