If you're not sure on how to assemble this kit - or just want to make it easier on yourself - you can select the option to have us pre-assemble the coilover kit for you. Here is what you get and what we do for our special $100 pre-assembly option:

  • We prep the surface of the shock hat in which the Fat Cat spring isolator gets glued to. We also prep the surface of the isolator as it is very slick and can become separated from the shock hat if not made to adhere better. This ensures the isolator stays in position and does not separate over time
  • We then use a slight bead of silicone to seat the coilover sleeves to eliminate having them turn when you adjust your spring heights after they're installed
  • We properly install the 5X Racing Shock Mount Kit
  • Installation video available on our YouTube channel and in the "Video Instructions" tab above
