1987 Lincoln Mark VII Suspension Enhancement

For sag from towing a trailer the best recommendation I can make is actually a weight distribution system. Suspension enhancement will help level your truck while towing. But the advantage to a weight distribution system is that it levels the vehicle…

Hey Micah! Pacbrake has actually been around for a long time, more than 60 years. We have had customers ask for these air bags in the past, and we've seen them on vehicles coming in. Until now, Firestone has been the go to since their quality is…

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…

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…

Hello Jeff, Sounds like you’ve got a big camper (about 4,000 lbs) on your 2024 F-350 dually, and when it’s loaded, the truck feels bouncy and sways a bit. That’s pretty common with heavy campers, especially if the suspension is still stock.…

The differences between the Firestone Ride Rite #F2613 and the Red Label #F2709 for your 2023 GMC Sierra 3500 Crew Cab Long Bed is the air pressure and max weight capacity. The Ride-Rite #F2613 are rated for 5,000lbs and 100 PSI, where the Red Label…

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…

I recommend going with the Air Lift LoadLifter 7500 XL Ultimate Air Helper Springs #AL89DQ for hauling around an in-bed camper with your 2024 Ford F-350 Super Duty. I really like this kit because it has the higher 7,500 lb rating (which you don't…

Hello David, thanks for reaching out. Between the TImbrens and the SumoSprings for your 2024 Toyota Tundra I definitely recommend the Sumos. They have a progressive spring rate so you don't get as rough of a ride when you are unloaded. Since your…

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…

There are a number of differences between the Firestone Ride-Rite Air Helper Springs #F2445 and Air Lift LoadLifter 5000 Ultimate Air Helper Springs #AL88299, starting with fit. While the Air Lift will fit all models of the 2018 Toyota Tundra, the…

Hi Brian; the SumoSprings #SS45FR will not fit your 2025 Sierra 1500 with Adaptive Ride Control. The answer from Sam is a little older and probably written before anyone knew about the restriction. I went ahead and corrected it, thank you for…
