Firestone Air Bag Spacers Needed for 2014 Ford F-350 with a 4" Lift


I put a 4 inch superlift in my 14 f350. The rear blocks were 3 inch. Do I order the 4 or 3 inch spacers?? Leaning towards the 3 inch due to common sense, or does the 4 inch accommodate the leveling factor of a 4 inch lift??

You actually may not even need that much of a spacer. Since the air bags themselves take up some space Firestone has put together a formula that you can use to help you determine what kind of spacer you need. To figure out the needed spacer simply measure the distance between where the brackets would be and choose from the following:

6-1/2" - 7-1/2" - Lift Spacer # F2536
7-1/2" - 8-1/2" - Lift Spacer # F2366
8-1/2" - 9-1/2" - Lift Spacer # F2367
9-1/2" - 10-1/2" - Lift Spacer # F2370
11-1/2" - 12-1/2" - Lift Spacer # F2374

Since you don't have a massive lift you will most likely need one of the first two options.

For your 2014 Ford F-350 we have two different Ride-Rite Air Helper Spring options, part # F2597 is Extra Heavy Duty and part # F2703 is Red Label Extreme Duty. Unless you use the F-350 for every day construction type jobs that require a lot of towing I recommend going with part # F2597.

I also recommend installing a compressor kit such as the Firestone Air Command I # F2158 so that you don't have to hunt down a compressor every time you need to add air to the air bags. This will also allow you to add air from the comfort of your cab.

Attached are sample installation videos for you to reference.
