This is a pair of genuine GM part number 10386222 that have been modified (shortened) to fit all 2003-2006 SSRs which are lowered 1.0″ to 1.6″. GM calls it an Auxiliary Spring or Bump Stop. It creates a soft stop for the fully compressed point of suspension travel.
These must be replaced in pairs only and that is what you are buying.
When you place an order for “ONE”….. you will receive a PAIR of Bump Stops.SSR Rear Lowering Springs
