Firestone4179 Coil-Rite Air Helper Spring Kit

Great product

The kit works great. It raises the suspension back to where it should be, which corrects the alignment problems. Drilling the holes in the control arms is a bit difficult, but other than that it is a very easy install. A good set of drill bits and a lift would have made it easier.

I use my car for work. I carry about 450 lbs of tools. I have used the other brand of Air Springs on my last three Vehicles. I had the other brand (Red Bags) installed on my Honda Pilot. The issue with the Honda Pilot is the coil spring is so coarse. (Like a coarse thread screw). There is not enough support for the air bag. I contacted the manufacturer of the Red air bag regarding this. They did not have a solution. I had to fill the lift system to Maximum pressure to get the lift I needed. The red air bags always leaked. I would have to fill them weekly. I had to replaced one red bag which was covered under warranty. Then after the warranty expired the system failed one red bag blew out. I purchased the Firestone system this time. I figured at least the color matched my car better. I was pleasantly surprised. The bags are of higher quality. The fittings are higher quality. I installed them over two months ago. They support the vehicle with half the pressure. I also have not had to refill them with air. I would recommend the Firestone brand over the other red bag.UPDATE. I have to withdraw my recommendation after 6 months. One bag split on the top corner of the bag. I contacted the manufacture.They require a picture of the defect for them to provide a replacement. So I am to remove the coil springs from my car to remove the defective bag. Reassemble my car so I can drive it. Then do it again when I get the new bag. Ridiculous. They could ship and charge you for the replacement. Then issue a credit when I provide a picture of the old bag. I am going to look for an alternative.

Must have for Honda Odyssey. I don't know how Honda specs out their rear suspension but it is way too soft. Anytime I trailer or carry more than a few people the rear end sags down worse than my five year old's face when he as to do homework. I pull a small trailer of motorcycles and even though tongue weight is about 250# the back end of my Odyssey sags down so much I can't back up into my driveway when I come home from a ride. The install was very straightforward although I will add that drilling the hole for the valve in the A-arm requires precise measurement and in the end you will still probably have to enlarge the hole a bit. In all a very easy install and the kit holds air without any leaks (I've had it hold 25 psi for a month with no drop in pressure). The rear end of my Odyssey now only sinks down an inch or two with the trailer on and it rides much better now.

I've had these installed for about 6 weeks now and they are holding up so far. They do make a little noise when hitting speed bumps and things of that nature. I have noticed that the noise will stop for a few days after going through a car wash.

Overall good quality components and materials. My only concern is that the rubber like support that takes the place of the jounce bumper does not have any metal or other rigid component that limits how much you can tighten the bolt securing it to the upper spring mount. I used loctite and tightened the bolt to no more than 5 ft. lbs. to prevent the rubber from being overly squeezed out by the bolt.

The directions indicated no drilling was needead to install. But I had to drill a hole through the bottom support. Also, the location of the hole is not the center of the support as I incorrectly assumed. I am not a mechanic but work on my cars alot. this was not an easy installation.

These did the trick for a year and a half. But, I'm kind of wishing I just got new springs at this point. It would have cost more and been a more difficult install but it seems like I'll need to do that anyway! I thought they might be nice for towing and I did pull a trailier once... I periodically checked the pressure and they actually held really well. I rarely had to add air. This winter, I was taking off the snow tires and they didn't look right. It seems like they failed at the top (perhaps stones collected beteween the bumper and the bag and water collected at the top depression and leaked INTO the bag. On Both of them. When I tried to pump them up, water burped out of the schraeder fill valves. Once I displaced the water, air just blew right through.

I have a 2005 odyssey that I camperized. Noticed the rear would sag when I had the trailer on with it fully loaded. After these bags I have no suspension sag at all. In fact I can level the van out completely loaded now to make the long highway drives super smooth and stable. I’ve put nearly 9000km on the bags now and not a single problem! Install was easy (outside of the rust on my van)Everyone with an odyssey should have these regardless if you tow anything. Improved ride and handling with the van empty as well

With the Pilots independent rear coil spring suspension, these vehicles will squat with a load causing extreme negative camber and inside tire wear. New HD coil springs helped but it was still a problem. Now with these air helper springs, heavy loads are easily managed by adjusting air pressure to keep it level and tire camber in spec. I mounted the inflation valves under the fuel door to keep clean and out of sight. The ride is still as smooth as before and cornering is improved with less body roll. Installation was straightforward if you have mechanical ability and good tools. I drilled the hole in the lower control arm larger than instructed, (1 inch) to allow extra room for the airbag valve. Be sure to drill in the center. And to prevent damage, added a few inches of 1/4" rubber tubing where it extends through the control arm.

The installation went well but it advertised that no drilling was needed, but I did have to drill a hole in my lower control arm for the air line to go through.

Excellent produit et relativement très fiable.
