Suspension Springs for a 2014 Tiffin Allegro Motorhome with a 24,000-lb Ford Chassis

Question

Question:

In my search for my 2014 Tiffin open road 35qba it shows it fitting. However, my Ford invoice sticker shows 24,000 chassis. In other searches if this system it says excludes 24-26k chassis. Can you clarify before I order?

I called Air Lift to confirm, and you are correct in that the LoadLifter 5000 Ultimate Air Springs, part # AL88240, are not compatible with your 24,000-lb chassis.

We do, however, have springs that are compatible. They are the SumoSprings Rebel Custom Helper Springs, part # SSF-173-40-2. These jounce-style springs are much easier to install and maintain than air springs, and they react appropriately to different loads (rather than the air springs needing manual adjustment when under different loads).

I've linked to a video installation of these springs for you to reference.

I really wish we had a diagram or a way to pull up where it'd be. Most likely under the overhang near the landing gear jacks as that's the most popular place. Check there first and then trace the wiring from the breakaway switch to see where…

The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…

Hey Doug! The Firestone Ride-Rite Air Helper Springs #F35FV are the right kit for your 2026 Ford F-350 FX4 dually. However, you will need to measure to be sure it fits. The distance from the top of your rear axle to the top of the jounce bump stop…

Hello Barry, Since you already have a weight distribution (WD) hitch and are only experiencing a little rear sag, I recommend going with SumoSprings. I typically only suggest Timbrens for those who are towing heavy loads regularly, as they can create…

Hi Todd, I know exactly the feeling you’re describing, and you’re definitely not alone. That floaty, pushy feeling at highway speeds, especially when trucks pass, is really common on the Sprinter 3500 chassis with a taller coach like your Tiburon,…

Hi Bill! Thanks for your pictures, they were extremely helpful! ^___^ The LCI Part #194170 on that tag you found means you have a 1621 pin box. The Gen-Y #GY45SR you were looking at is specifically for the Lippert 1116 and 1716 pin boxes, so you will…

Answer 11

Hey Don, thanks for reaching out. Yeah, the driver’s side on those F53 chassis can get tight, you’ve usually got brake lines, wiring, or a bracket sitting right where you want that Timbren to live. You’re doing the right thing paying attention to it,…
