Does Firestone Ride-Rite Air Helper Spring Have to Install in Front Alignment Hole
Updated 03/11/2026 | Published 03/07/2026
Question:
Hello, Installing the F35FV kit on my 2019 F350 SD and the instructions say to install the alignment pin and combo stud into the frontinch alignment holes. When I do that, the air spring does not line up with the lower bracket. However, if I install the studs into the rear alignment holes it lines up perfectly with the lower bracket. Is this an acceptable installation or do they have to go in the fwd holes and be out of alignment? Thank you

Hey James! The Firestone Ride-Rite Air Helper Springs # F35FV call for the use of the front holes when you install them. However, you can use the other set of holes if that gives you better alignment. Check out the installation video below starting at the 8 minute mark. Kevin marked the bags ahead of time to make sure they're aligned properly, I would follow the same steps.
Are you adding these for towing or something else?

The ride is a little bit rougher than stock, but it does do the job. Ultimately, I wish it was a smoother ride.

I used the rear holes as everything lined up that way on my 2024 F350. I've had them installed multiple months and towed a 16,500 lb 5th wheel and no issues. Plus I tow a 6,000 lb work trailer on a regular basis. The air bags work great and keep my truck level and riding great.
