Should I Get Loadlifter 5000 Or 7500 For Towing A 15K Fifth Wheel

Question

Question:

I have 2012 F350 SRW. I just recently bought a 5th wheel 15k lbs and I’ve been between getting the Air Lift 5000 Ultimate Plus or the 7500xl. I’m not sure which would be more suitable. The payload is less than 4k so my initial thought was that 5000 was fine to help out, but also don’t want to over burden the bags. Are they a good option or would the 7500xl be better? Pin weight on the camper is about 2.1k if that helps too. Thank you!

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 7500 kits are used on vehicles that have a constant heavy load in the bed like a salt spreader or truck bed camper.

For your 2012 Ford F-350 I recommend the Air lift Loadlifter 5000 Ultimate # AL88396. I prefer the ultimate kit because the air bags feature internal jounce bumpers. This adds stability, and also acts as a failsafe if you ever were to lose pressure. 5000 lbs of capacity is more than enough for a 15K camper, and you will not be coming close to over-burdening the bags.

You also have the option of adding an on board compressor. For that I recommend the Air Lift Wireless compressor # AL25980. This is a single path compressor that can be controlled with the included remote, or via the Air Lift smartphone app. The smartphone app is very nice to have. Not only does it give you full control at your fingertips, but you have access to real time diagnostics that standard compressors do not offer.

I have linked a few of our install and review videos below if you want to take a look.

Same question but different specs. I have a 2026 F350 DRW and I am pulling a 5th wheel, Alliance 372rk. Fully loaded the camper is 16800# and the pin weight is approx 3000-3200#. The payload of my truck is 5300#. Am I safe with the 5000 or should I step up to the 7500?

@Steve Honestly for that I would lean towards the 7,500 just so you wouldn't be working them as hard. Sounds like your pin weight would be under 5K but you would be cutting it close. The 7,500 gives you a bit of a safety net, so that is what I would go with. I recommend the following: - Air Lift LoadLifter 7500 XL Ultimate Air Helper Springs - Rear Axle # AL83DQ Were you wanting to do an onboard compressor as well?

@JesseM Yes, I would want the compressor as well. I have a 2026 F350 Platinum dually. I am assuming the 2025 kit will work, is that correct?

@Steve Yes it will fit the 2025 and 2026 model as well. Typically I recommend Bluetooth compressors so as long as you are up for controlling and monitoring with your smartphone, I recommend the following: - Air Lift WirelessAIR Compressor System for Air Helper Springs - Bluetooth - EZ Mount # AL58WQ

Hello, Same thing here I talked to two shops that install Air Lift bags and even though I originally wanted 7500 lbs bags the both recommended that I go with the 5000 lb bags. Truck is a 2022 3500 srw Ram 5th wheel dry weight pin weight is around 1700 so little.more with my stuff in it. Want to see what you guys think 5000 lb or 7500 lbs bags? Don't want under rated but dont want over kill either. Thanks for your help you will be the deciding factor. Gary

@Gary Honestly for 1,700 pin weight I agree with the shops you visited. The 5000 bags will be the best option for that setup. There is just no reason to do 7500 its just extra capacity you don't need. Typically I only recommend the 7500 for trucks with a constant heavy load in the bed like a truck bed camper or salt spreader. That or BIG campers that are pushing the limits of the 5000. That being said, here is what I recommend for your 2022 Ram 3500 SRW: - Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers - Rear Axle # AL88231 - Air Lift WirelessAIR Compressor System for Air Helper Springs - Remote - Bluetooth # AL74000 Let me know if you have any questions or if there is anything else you need!

I would love to jump in on this thread too is that is OK. Trying to make the same decision. Truck = 2025 F350 with Tremor Package. Payload is 3880 lb. RV = 38 foot Grand Design Momentum 320G toyhauler; Pin Weight = 2300lb; GVWR=16400lb. Dry weight=13100lb. Toys hauled = 4 mountain bikes I am leaning towards the 7500lb air bag, but am concerned that it will make the ride rough.

@Rael Hey Rael, For your truck and camper combo I definitely recommend the Air Lift LoadLifter 5000 part # AL29DQ. Technically the 7500 would fit and work but they just aren't necessary here and you would be paying for extra capacity that you don't need. The 5000 will be more than sufficient, and you will be safely under the max capacity with room to spare. Typically the 7500 are only needed for trucks with a constant heavy load in the bed like an in-bed camper. You will be good with the 5000. I also recommend the # AL25980EZ wireless compressor to go with it.

Will the 7.5K have a rougher unloaded ride than the 5K system?

Jesse M.

5/5/2026

@Bob3 No not necessarily a rougher ride unloaded since you can run both at a minimum of 5 PSI. I just usually try to discourage folks from paying more $$$ for extra capacity they don't need. For most towing applications the 5000 are more than enough.

It sounds like the purpose of getting the air helper spring would be to counteract the 1 inch compression you're getting in your rear suspension caused by the pin weight of your 5th wheel. If that's the case, I believe that the AirLift 5000…
