Helper springs
 

Just did rear leaf springs and shackles an all bushings,on the old 86.i Was looking in to some helper springs to keep the new springs happy. I do work the truck towing and loading the bed up on a dayly bases . Has any of you used helper springs? Any advice on what kind? Thx for your input

I just installed rear air-bags on my F250. I only have 1 day of experience with them but I totally recommend them to anyone who would like to improve how their truck carries a load. I got mine used off of a truck at the wrecker.

I don't know what brand they were sold as, but it says Firestone Airstroke on the rubber.
