What is the PSI Range for Firestone Coil-Rite Air Helper Springs # F4174  

Question:

Just installed them and the instruction page I have says to refer to another page that I cannot find for inflation instructions. What is the max inflation on the F4174 kit. I have read my instructions front to back and cant find it. Thanks!

In the instructions that I have linked for you, under Figure B it states the recommended operating pressures for Firestone air springs # F4174 are from 5 psi to 35 psi. So 35 psi is the max you will want to put in the bag in this system. In step 9 it is recommended to inflate/deflate in 5 psi increments to find the ideal riding condition for you and the vehicle.
