A shock


Houdaille and other rotary shock absorbers

This is a rotary shock absorber (as opposed to the more common Delco piston shock; an easy way to identify a Houdaille shock is by its round clocklike housing) A very labor intensive shock to rebuild, especially if frozen (arm doesn't move); they must be rebuilt on an individual basis. Please allow 10 workday turnaround.

Ford - Mercury - Lincoln

  • $195.00 each rebuilding cost applies to "rebuildable" cores: arm turns, internal parts move sort of quietly (no nasty grinding sound). Most "non-rebuildable" units can be rebuilt, but with some extra work. Expected cost is $245.00 each.
  • If we ship first, we will charge $245 plus $100 core deposit for each shock. All returned cores get full refund, regardless if they are "rebuildable" or not, as described above.
