Recommendations For 2019 Ram 1500 Classic Rear Suspension Sag With Weight Distribution Hitch


I have a 2019 Ram 1500 Classic Crew Cab 4WD and tow a 34foot TT which comes in at 7,500 GVWR, 6200 dry weight. The truck bed is full of gear and 4 of us in truck. I have a E2 weight distribution/sway control that is rated 800lbs/8,000lbs. Power wise, it hauls it fine. However, I am getting several inches of squat on my truck and wondering if Air Lift suspension bags into existing factory rear coils or Heavy Duty Coil Springs replace factory ones would be better. Thoughts?

The Fastway e2 Weight Distribution # FA94-00-0800 is rated for a trailer tongue weight of 400-800lbs. I would use a BetterWeigh Mobile Tongue Weight and Payload Scale # C51701 to ensure that your travel trailer does not exceed 800lbs of tongue weight when you have it loaded with all your gear.

If you are below the 800lbs tongue weight you will simply need to adjust the angle of the hitch head to get more weight transfer through the bars on the front of your 2019 Ram 1500 Classic. You will do this by loosening the 2 bolt sets that hold the hitch head to the drop shank and adding washers to give the head more angle and putting more weight on the spring bars which will transfer more weight to the front of your Ram. It is important that the weight on the bars levels your Ram to know that there is enough weight on the spring bars to reduce trailer sway.

If you are above the 800lbs you can swap the spring bars for a set with a higher rating. A set of the Round Spring Bar for Fastway e2 Weight Distribution Systems # FA94-02-1099 will allow for a hitch weight of 600-1000lbs. These will work with your current hitch and just replace your current 800lb bars.

You should not need a set of air bags or heavy duty springs to level your Ram when towing with a properly adjusted weight distribution hitch. Unless you are also hauling a considerable amount of weight in the bed of your truck as well. You should still ensure that the weight distribution is properly set to level your Ram when the bed is empty.

If you use your Ram as an everyday driver and not just for hauling the travel trailer the Air Lift 1000 Heavy Duty Air Helper Springs # AL60818HD will help you level your Ram with additional payload in the bed. This kit will only fit if you do not already have an air ride suspension from the factory. They are rated for 2,100lbs of support and work by pushing in between the spring coils when inflated. This will provide additional support to the springs when it is needed and retain the factory smooth ride when you are driving the Ram everyday without additional weight.

I recommend using the Air Lift WirelessAIR Compressor System # AL74000EZ to allow you to wirelessly control the air pressure in the bags. You can do this from either the wireless remote or with the Air Lift smartphone app on your smartphone. It will maintain the air pressure settings to within 3psi of where you set each bag. You can also adjust each bag individually for uneven loads.
