Air bags or "Bump Stop" type suspension

I'm towing a 2020 Grand Design, 10500# (when fully loaded) 30' fiver with a pin weight topping out around 1900#. The tow rig is a 2014 F250 6.7 diesel super cab with 6 3/4 bed. The truck squats just a bit when I haul and just want to get it up to level. I've been shopping the Air Lift 7200 bags with the remote and on board compressor, and the Timbren brand "bump stops". Any feedback on either or both out there? Thanks.
  • Currently on my third GMC truck (in the last 12 years) with Firestone RideRite air bags with their Air Command compressor system on-board. The previous two trucks had digital gauges and a switch under dash to inflate/deflate the bags.......my current system has a wireless remote control used to inflate/deflate the bags. Love it!!! You can stand several yards away from your TV, eyeball the truck, inflate/deflate the bags using the remote until she sits level...........

    Over the last 12 years the systems I have had preformed flawlessly, performed as they should......IMO, great product, no drill installation making them so easy to install yourself with just common hand/power tools.

    Running empty with only 10 lbs in the bags so as to not damage them (recommended by manufacturer) with no effect on ride/handling, they have been up as high as 85 lbs depending on the situation but typically 30-55 lbs is the range I most often use, no matter they provide improved performance to ride, stability and handling............I never leave home with out them!!!!
  • I have the Firestone bags on my F250.

    Because they are adjustable and when I dump the air, I get pretty close to stock ride.

    You are saying your 250 sets lower in the rear than the front when hitched?

    If so air bags are the BEST option, air to get truck "LEVEL" not unloaded stance!!!

    If stock shocks add Bilstein's. This combo you WILL thank me.

    Sad a 250 needs help with that little pin.

    I found my Ford did not engage overload springs until there was rear squat. Since the F250 sits 2" lower in the rear than the F350, it is even more pronounced. This was why I suggested preloading the OEM overloads before adding more suspension - It can handle more weight, but just engages later in the travel resulting in squat. My OEM suspension with the upper overloads that come with the camper package was able handle 4000 lbs payload but had to be preloaded if you did not want squat.
  • At stock height, I never needed any kind of suspension aids to keep my 2014 2500 CTD from squatting. My 14k 5ver made it perfectly level.

    After I leveled the front end, I still didn't need it for most of my trailers like my 6k cattle trailer, but the 5ver made it squat. I didn't want to go with Timbrens because they have made the rider harsher on past vehicles. I didn't want to go with air backs because I use this truck off road and I didn't want anything I had to maintain.

    I went with Sumosprings Rebels "blue" kit with a 1 inch spacer. They are a two piece design that separate when my axle is articulated off road, and they make for a much softer rife than Timbrens. They actually made the ride softer than stock and the truck sits level again with my 5ver.

    They make a "black" kit that has a higher load rating, but also is a much stiffer ride. In my opinion, they are not needed for most people here unless you have a trailer hooked up 24/7. This kit is equal to Timbrens in regards to stiffness.

    Here is an article about them in Trailerlife.com.

  • Not sure about those air bags but when I installed my Firestones on my 2008 Ram I had to remove the "Jounce rubbers"aka bump stops. If they have online installation instructions you may be able to figure out if you can have both installed at the same time.
  • Your other choice is preload your OEM helper springs more. Look into Torklift StableLoad pads for the upper springs or wedges for the lower springs.
  • I like my bags but declined the onboard air compressor. I use a bike air pump or Ryobi battery pump.

    I’ve had both. Currently have the Timbrens, and about to replace them with bags.
