Firestone 4100 Coil-Rite Air Springs - 4100

Not super easy to install, but not too bad. There's a couple YouTube videos that help. Nice bags though.

Used for my 32 ft. RV, easy install, however; I was also replacing my springs. I've had them on for about a year now and holding up well.

They work great. .warm up air bag in sun or some way To install simply fold then get hose clamp on it 2 inches from top. Tighten clamp then shove in. Loosen clamp lower it a couple inches then retighten. Push up and in some more repeat. This way works.

The product itself is great. Durable, and it makes a huge difference in ride quality. Unfortunately, Amazon is not a licensed reseller of this item, meaning that Firestone does not need to honor the Warranty if they chose not to. I found this out the hard way. That being said, I had a leak in one of the preinstalled fittings on the air line, and Amazon took care of it immediately. Installation wasn't easy, but it wasn't the nightmare I thought it would be. Watch the vids on YouTube and have some patience and it'll go together without too much trouble. Taking the old bags out was nearly as much trouble as installing the new ones. 4 stars instead of 5 due to Amazon not mentioning that they are not an authorized reseller.

I knew that the air bags in my RV had been bad but I was being lazy about fixing it. I finally bit the bullet and bought these. It was a breeze to install. I cut out the old ones into a spiral with some tin snips and a Rambo knife. Then I just pulled 'em out.Youtube was a big help. I compressed the heck out of them with some hose clamps and zip ties. I lubed them up with some dish soap. They slid up through a hole in the bottom control arm. Don't make the mistake I did and carelessly put them in with the valve up. Luckily I caught myself before I got it too far in! Tip: I used a bottle jack to press it up and a big screw drive to hold it up to get the lower plate installed. The plates were the hardest part. Don't forget to put the upper one on before you put the last bit through. It is a little persnickety, in my experience.It probably takes a shade tree guy like me about 30 - 45 minute per side. That was my average, even with the mess up. I'm glad I finally did this (right before I give it to my kids)!

These were installed on the front end of my motorhome. The difference was night to day!! Definetly stabilized the front endSeems to be a great product. Haven't had much of a chance to try it out on a long distance. Somewhat difficult to install but paid to watch videos of others and how they did it.

Product OK but don't believe the"easy to install" reviews. First- getting the old out is like pulling an elephant through a mouse hole. Second- directions say to simply twist and shove it into the bottom hole with a little soap. It's more like twisting a10" I beam and the soap is only useful to wash your hands after completing a nearly impossible task. I placed it between two pieces of 2×10 and used clamps to flatten and draw the air out, put on the valve cap to retain vacuum, still difficult to twist but facilitated with several worm clamps, then swore a lot to squeeze in the last inch or two in the coil spring. Third- install/aligning the top and bottom doughnuts requires dexterity of a surgeon and patience of a Saint (neither of which my wife says I have). It can be done without disassembly of the front end of the vehicle, but in retrospect next time my baby is getting yanked apart and probably not by me. BTW- my skill level is usually very high but this reached my limits while balancing 15000 pounds over my head.

Installed these on a 1992 Fleetwood Flair motorhome on Chev P30 series chassis. I included details of how we installed in my original Amazon review but that review was rejected for reasons that I was unable to determine, so I'm trying again with fewer (pretty much no) details other than photos. Can't for the life of me figure out what Amazon didn't like about original review. Hopefully the annotated photos will be enough to be of some help. Sorry I can't provide more info on how to go about installing so as to minimize your effort. I hope the pics help. Good luck with your install. It is definitely worth the effort. Thanks.
