Notes:

• New control arm service assemblies do not come with the bump stops installed. You can in theory reuse your "old" bumpstops with the "new" control arms, but you will need a pair of wide sheetmetal pliers to hold the stop stationary and a pneumatic air wrench to turn the nut.
  
• Police suspension springs have a relatively high spring rate. And a vehicle with police springs installed will not have the bumpstops contact the frame as frequently as one with civilian springs installed.
