We do have a potential option for you, but the Air Lift LoadLifter 5000 # AL88205 is only going to fit vehicles with a fully boxed frame, so if your 2018 GMC Savanna 3500 is a van they are not going to fit.

Since there is no air bag kit available, we recommend the Timbren Rear Suspension Enhancement System # TGMRG35. These are rubber jounce-style springs that will sit above the axle and help reduce sagging and absorb shock. The springs themselves have a 3,600 lb capacity and they are an easy no-drill add on.

We also have these available in a 6,000 lb capacity as part # TUR350 if you would like something a bit more heavy duty. I have linked an install video below if you want to take a look.

Since the pin weight of your camper is 2.1k, I recommend going with the LoadLifter 5000 opposed to the 7500. While technically there is not reason you couldn't use the 7500 kit, it really is not necessary for a camper like yours. Generally the…

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…
