What Size are the Air Bags for Firestone Ride-Rite Red Label for a 2015 Ram 2500

Question:

I am looking to use the bags in a daystar cradle. I just want to make sure it is no larger than 6, also do these bags have internal bump stops?

The air bags in Firestone kit # F2701 have a maximum diameter of 7.52 inches at the widest point, compressed height of 3 inches, and extended height of 8.91 inches. Also, this kit does not fit the 2015 Ram 2500. The Ride-Rite Red Label kit that fits is # F2706 but its air springs are the same size.

Firestone air bags do not have internal bump stops. According to Firestone the reason that other air bags have those is because at lower psi the bags can fail at the crimps but Firestone's air springs are more robust thus eliminating the need for internal bump stops.

Also the claim from Daystar that 20 percent of the stock suspension travel is lost with air bags is a bit misleading as it depends on how much air pressure you are running in the bags.
