### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works good on Avalanche 1500, valve on top
  

*by S***N on Reviewed in the United States on May 12, 2019*

Easy to install, works great. Suggested to not use T for controlling both bags from one valve since load can shift causing one side to deflate and other to inflate more. Use two separate valves or get the remote control fill modules. That's the next step. Installed on an Avalanche 1500. Definitely gives more stability and load balance for heavier tongue weight. Around 25psi seems decent on average. Should got em years ago. They will seem to lose pressure for the first couple days but should be fine after that. Valves can mount on the top. I drilled out the hole through existing rubber cap thing in there a bit to create a little more room for valve and hose to go through.

    Great airbags
  

*by D***N on Reviewed in the United States on May 24, 2021*

I'm using them on my 2002 Chevy Avalanche that pulls a 70001b RV.It raised the shocks at 30lbs of air to level off the trailer and the truck.Its like riding on a cloud going down the hwy. Can now pull out of my driveway without scraping the trailer hitch. My neighbor spent 400$ to have different bags installed. I had two friends that are mechanically inclined figure it all out. They had them installed in 2 hours.  Would recommend

    Really hard to install
  

*by S***Y on Reviewed in the United States on April 13, 2021*

So far they're doing ok. One thing though, oh my gosh they are NOT easy to install. While doing it I kept thinking how I was going to write a review of how hard it was, lol. It said easy to install well it's not. Took me forever to squeeze them into the coil then try to take the 3 inch hose out to put the final one in. I'm a girl and have skinny long hands and fingers and it was a nightmare just to grab the hose to push down into the bag. Very hard to do and I work on my own cars and pretty strong.
