If you are talking about Reese installation kit # RP50140-58, make sure that you do not have a 1500 with the 8 foot bed and a Mega Cab (if there is such an animal) because that is the only thing this kit does not fit.

To determine if it would interfere with Firestone air bags you have to look at where each installs. The Reese installation kit has front brackets that fit on the outside of the frame and also block part of the bottom of the frame. The rear brackets are mounted on the inside of the frame and cover part of the bottom of the frame. See the instructions link I have added.

The Firestone kit for the Mega Cab is # F2299 installs on the inside and bottom of the frame above the axle. (It attaches to the side and bottom of the jounce bumper brace.) It is possible that this kit would still work as long as none of the Reese kit covers the jounce bumper. I have linked instructions for the Firestone kit as well.

A kit that I am confident will not interfere is the Timbren system # TDR2500CA. This is because it replaces the existing bump stop. These springs would be more ideal for towing static loads like a 5th wheel trailer. Air bags are better if you are frequently towing different sized loads.

I have included a link to a video showing installation of the Timbren system and a link to our FAQ articles on Timbren and Firestone systems.
