ATQ has developed a direct fit replacement set of the outer leaf spring isolator pads, made of a proprietary polyurethane composite material to replace the inadequate nylon OEM outer spring isolator pads. Torture tested to ensure durability and longevity, with a 124,000 mile / 200,000km warranty to back them up.


  • This kit includes a set of 4 outer isolator pads
  • This product is a direct replacement for the OEM 2015-2020 Ford F-150 outer leaf spring isolator pads.
  • 2 Tubes of Prothane Super Grease is included with each order *when available

** Installation Tip **
