      A:

      Hi Shopper, good question! To install the twistin real coil spring boosters jack up the car, remove the wheels and screw them into the widest gap of the coil spring wire with a deep-well socket and a breaker bar. For help with your project, I would recommend purchasing a Chilton or Haynes Repair Manual for your vehicle, not only will it explain how to replace this part, but you'll find it handy for many more projects on your vehicle.
