Firestone4101 Coil-Rite Air Springs - 4101

This kit works in a 2017 Ford E450 class c motorhome with the v10 engine. It is perfect and installs in a couple of hours. It comes with instructions. I did not have a bolt protruding upward inside the spring so I did not need the acorn shaped spacers and it all worked out great. It’s difficult to thread the hose on top so be patient and You will have to pop the top of the spring out to feed the bag down into the spring.

Easier to install than the instructions said

Not sure who the genius is who decided that the kit that fits my F-350 required 90 degree ends at the air spring, but he should be fired. First off, you should never route the air line between spring coils, period. That should be common sense, but I digress. Second, there's a massive hole in the middle of the upper spring perch which allows perfect access to the air spring with a straight coupler... with the 90 degree ends attached to the air line, the valve at the top of the spring is forced into a strange angle and the polyurethane spacer doesn't sit right... the movement of the suspension begins to unscrew the coupler from the valve and you lose all pressure and risk damaging the air spring. These 90 degree ends are made from cheap brass and will most likely work harden and crack if you attempt to bend them straight. For my application, using a valve extender made for inner dually tires mounted through a hole in the inner fender was the best solution, though it adds more failure points to the system. I spent a little time looking for 1/4 inch push-lock air line Schrader couplers but didn't find anything like that... not sure they exist, but they would be the perfect solution. The push-lock Schrader valves that came with the kit leak where the air line is inserted even though the line is cut perfectly square and free of burs and nicks and flat spots... They're just low quality and you can buy better ones pretty cheaply.

Works great

I have an 89 F250 2wd, this 4101 Coil-Rite fit inside, its a little tricky getting it to line up so that the offset shrader valve doesn't get crushed when the coil gets cranked back into place. I spent considerable time running the air line to a secure easy to reach place but wouldn't you know it, they leak. I just pulled them and cut the zip ties and just use the valve on top of the bag. Its easy enough to reach even with the tires on. I'm trying to solve a swaying under load issue and this and the bags in the back should do the trick.

So, after researching the Ride Rite website, I found these bags came up as recommended for the Econoline series of vans so I went ahead and ordered. My mechanic installed them both in about an hour, no issues and modifications needed!After I had a 2" lift installed on my van, I decided I wanted to install these bags so I could adjust the front end to "level" out the suspension and they fit the bill perfectly. At 60lbs, it raised the front almost another 1" so that it rides level now and the best part, it rides like a Cadillac! Very pleased.Some recommendations, install some good shocks like billsteins, and plan on getting your front end aligned after you find your desired pressure / height and enjoy the new ride!!

I give this 5 stars because it is a good product for a (Ford). Did not know before ordering, had to return for the right one. This one has the air valves off set, not like the photo. The description says it fits the P-30, P-30 is a Chevy. (The P-30 # is Firestone W237604100 Coil-Rite Kit).

Seems to help a lot but the instructions are terrible.

This air bag kit worked perfect on my 1976 e150. The hardest part was getting the bag inside the spring. It was a cold day out so I couldn’t compress the bag enough. Ran hot water over the bag and managed to zip tie it enough to get inside the spring. Seems good quality and can’t wait for road trip. Oooops everything is closed thanks to corona virus! I’ll camp in my driveway!

I expected better from a brand name like Firestone. The first thing I noticed was the valve stem integrated into the bag. That was disappointing. I would have much preferred an NPT port that I could thread in a fitting so if there is any leakage or need to redirect with a 90 or create more height then its easy to do. Then the supplied fitting to attach to the bag is a female 90 that screws on the valve stem on one end, and a barb that goes into the air line. No clamp or push-in fitting, just the barb. That's not giving me a good feeling that its not going to leak. And sure enough both sides leaked, but not until I had everything together and was doing a final test before I put the wheels back on. So I had to fiddle with undoing the fitting from the air bag while it was inside the coils spring. That was not fun once, but I had to do both sides. And since that type of fitting (female valve stem to...well any other type of fitting, I had to just cut the plastic air line and push the barb into new section. I can't see that lasting for long without leaking and so I will be searching for a fitting to replace it with so when it inevitably leaks I will have to take the wheels off and fiddle with changing those fittings again.So, very disappointed in Firestone. It reminds me more of something off of Alibaba rather than made in America. (It is made in America, right? I think that's what it says....). Well the 2 hour install turned into 4 days....not entirely Firestone's fault. It is a 2004, and I had trouble taking the shocks off, probably because they were probably original, then I had to get new shocks but nobody had them in stock so I had to order them, etc, etc. But after all that to find out the fittings leaked....well It just added frustration on top of frustration.I've got rear bags arriving later this week. I am hoping the kit is better quality.Stay tuned.....

One of the fittings 90 degree is leaking air I filled out the product support form on Firestone's website 3 times still not hearing from them - do they know what customer support is??

90 deg. Fitting was faulty on one side and leaked. Poor quality control. I should have gone for Airlift.
