Firestone Industrial Air Spring
QR Code Link to This Post
This is a replacement air spring for a Reese fifth wheel king pin box. It has never been used, though it has a little bit of dust on it, which is how it came to me when I purchased it in 2021 from mrostop.com. I bought it to replace the air bag in my fifth wheel hitch, but I ended up having to total the trailer before I could replace the air bag in the hitch.
