(25) Write a Review

Product Description

Premature failure of the nylon OEM outer spring isolator pads are an unfortunately common issue with the 2015-2020 Ford F-150 series trucks, often causing annoying rear end clunks. But a one-and-done solution is here:

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 **

Each tube of Prothane Super Grease covers the face of two isolator pads. Cut open the tube prior to installation and use half of each tube on the face of each pad. Once evenly coated, install the pads. Application of the provided grease is required for problem free usage, and warranty is voided if the grease is improperly applied, or not applied at all.

Replaces OEM Part Number : FL3Z-5586-B and FL3Z-5586-A

    Parts shipped to me through regular service Canada Post in a timely fashion. The Parts were packaged with care for shipping and arrived in perfect condition. The isolator pads appear to be of solid manufacture quality, and made of materials that will be a definite improvement in functionality over the stock parts which they replaced. Installation was a little bit of a challenge, however I expected that going into the job. I have noticed since Installation that the creaking over uneven bumps is now gone. The ride quality seems to be slightly smoother, as well. I will recommend this kit to others!
