I've come across a few questions regarding the Firestone model # 2299 kit for the Cummins throughout the forum and figured I would write up a simple FAQ to keep many of these questions in one thread.

So here we have it..

Firestone Kit 2299 FAQ's:

Q: Will this kit work with a B&W Gooseneck Hitch?
A: Yes, the kit's upper brackets bolt into the inside of the vehicle's frame while the gooseneck hitch uses the outside of the frame to mount.

Q: Will this kit work with my lifted truck?
A: Yes, however additional hardware does become required to make up for the space between the axle and the frame. Depending on how much of a lift you have on your vehicle will determine which lift spacers you would want to choose.

A: Yes, all Firestone products come with installation manuals included. If by chance you do not receieve an installation manual you can find it here :

as well as a generic video of an airbag installation here :
