Firestone 4108 Rear Coil Rite Air Spring kit for Grand Marquis Town Car H2 Yukon Crown Victoria Tahoe Escalade

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.

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

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.

Very easy to install and works great. The first weekend after I installed them I towed a trailer with a 6 seater Polaris Ranger 150 miles. No sagging and bouncing. Then loaded 1,200 pound of deer corn in the back of the Avalanche and in front of the trailer adding to the tongue weight. It still sat nice and level with no sagging.

They are nice and worth the cost, but one or the two is leaking. I pulled the springs to install them so it was pretty easy and gentle. It's too much or a pain to return. I just fill it every few days

Fast delivery, item as displayed

I used these on my 3” lifted 2010 Toyota 4Runner. They work great and very easy to use

The Chevy lean is a disease the GMs get sagging by 1 inch on drivers side because the gas tank and driver on the same side after 100,000 miles I'm still experimenting adding more air in one then the other. 1st test saved an 1/4 inch. Great deal should have them anyways may save the lean in the long run. Super Super easy to install

5 Stars for Hitchweb who I bought it from. They helped me with all my issues and were quick to resolve my problemsVery difficult to install. I recommend warming the rubber before installing as it's very stiff and doesn't fit inside the coil as well as some reviewers describe. Also, I'm getting some air leaks which makes the entire system useless.
