No, the Ride-Rite kits are designed to work in the original suspension height and configuration. Changes to height can hurt performance or allow the parts to be stretched or compressed beyond their capability, resulting in a premature failure.
Absolutely not. Only the vehicle manufacturer can set the GVWR. Even with the air springs, you have the same brakes, axles, bearings and frame stiffness which in part determine the vehicles load capability. The Ride- Rite air helper springs simply allow you to carry the maximum capacity of your truck more comfortably and without suspension sag and the poor handling that comes with it.
The life expectancy depends on a variety of factors, including heat, environmental conditions and how hard you are using your truck. Due to Firestone superior construction and rubber compounds, which are the same as Firestone uses on Firestone Airide™ commercial vehicle air springs, it is not unusual to see the Firestone air springs last for 4 or 5 years. When they weather- check (or dry-rot), like a tire, they need replaced.
Push the air line toward the body of the fitting, this will also force the collett or collar, of the air fitting toward the fitting. Hold the collett against the fitting, you can use a 5/16” open end wrench to do this and then pull the air line out after the collett releases the air line.
Firestone has lifted kits available for some lifted and lowered applications.
Mix a solution of soap and water (about 1/5 liquid soap to 4/5 water) and spray it on the air line fittings, air spring and compressor body and head (if you have an air compressor). If the fittings are leaking at the threads, tighten them or apply thread sealant. If the fitting is leaking at the air line, remove the air line, re-cut it squarely and re-insert.
Yes, but adding a “T” fitting will not allow you to level side-to-side and will allow air to go from one side to the other, which sacrifices some of the stability that the Ride-Rite kit adds. Firestone does not include "T" fittings in the kits for this reason.
No, the kit comes with 2 inflation valves, one for each side of the vehicle. The inflation valves are the same as are used on a tire. When you check your tires monthly, check your air spring pressure as well. You can add air using any means you would use to inflate your tires. Your local Firestone Tire and Service center provides free compressed air to their customers.
