With a 4.5-inch stroke and 127.0 maximum force rating, it is intended to provide consistent hood lift and controlled support for the listed Ford and Mercury models. Part number 4550 is also referenced under AMS Automotive 4550.

  • Weak or inconsistent hood support
  • Slow or uneven hood opening
  • Need for replacement on worn gas struts
  • Loss of controlled hood hold on the listed Ford and Mercury vehicles

Installation Notes

Verify the end fittings and length before installation. This StrongArm hood lift support uses specific-fit ball socket connections, so matching the vehicle application is important. For safe and reliable hood support, replace lift supports in pairs when servicing the hood system.
