Question:
Hi, I want to add some Firestone Coil-Rite helper springs to my 2020 Toyota 4Runner. I have Toytec 2 inch lift springs in the rear. What set set would I need for this application? Thanks!

The Firestone Coil-Rite Air Helper Springs # F4135 may fit your 2020 Toyota 4Runner with the Toytec 2" lift springs. You will need to verify your Toytec springs have the same inner diameter as your factory springs. If you no longer have the factory springs I will need for you to measure the inner diameter of your Toytec spring as we do not have a way to find the specs for that spring.
