Air Lift 59501 Ride Control Rear Air Spring Kit, Black

Fit my 95 Chevy K1500 4x4 pickup truck perfectly. This system is made nicely, very stout brackets with #8 grade bolts for mounting brackets to truck chassis. The bags seem to be engineered and designed well. However, use caution and ease when tightening bottom bolt and top air fitting into the bag so as not to dislodge the integrated nut. This system would have been top notch if the air fittings were brass and not plastic and if the air line were some other material other than plastic but overall seems to fit the bill and works well.Just installed this system this evening so cannot provide a complete, thorough review reference how the system functions with loads and air retention in bags.A straightforward install, just read the install booklet prior to attempting the installation, contains some pertinent information that makes it go smoother. Plus it helps to have someone else to help you when installing the top brackets, you know the 'whole tighten bolts' scene-"You got the nut held yet?"Whomever stated this was a 2 hour install is a deceiver for certain..they must have installed the system on a naked frame with no body, no tires, no brake lines, fuel tank, etc; It took me about 5 hours to install this system, so allot at the least an evening for the install.AND please be sure you have a level, concrete working surface to work off of in order to keep axle straight which is crucial to obtaining the proper ride height so the bags are mounted properly. And put on a pair of old working coveralls...Overall, the installation is straightforward and enjoyable if you are a mechanically inclined individual. Oh by the way, make sure you have a good quality, brand new 3/8" drill bit on hand, to drill through the thick wall chassis. Makes it soooo much easier...chris

I added these to my 2000 GMC Sierra 1500 as I recently purchased a 5th wheel camper and needed the additional load capacity. They are FLAWLESS!! Easy installation and work better than I had thought possible! I wish I had a set of these a LONG time ago - especially when hauling a heavy load of dirt, sand, or anything else in my bed. These completely took the sag out of my rear end, and (when loaded) provide a silky smooth ride.The only drawback (for those that like a smooth ride) is that, even when at the minimum recommended air pressure the ride is quite bumpy...it doesn't bother me any as I expect that from a 4X4 working truck.Overall a GREAT product when combined with the Air Lift 25592 On Board Compressor System and HIGHLY recommended!

Highly recommended, good product and really easy to install. It is really recommended to have a few good tools, including several cheap or one really good drill bit. A nice way to put this on is to tap the holes and then weld the joints for permanent installation. Routing the hoses really needs to have some plastic coil wrap to protect the small lines. I mounted the fillers in both sides of the license plate and are really easy to access- it is the place recommended and it is a really good spot. I wrapped my brake controller wire, trailer wires ad hoses in one wrap and put on zip ties every location it was possible to give it positive location.

I have a long box chevy pickup that I regularly have loaded with heavy items and pulling a trailer. I researched these products to death prior to buying one. I wanted the ability to adjust my truck back to normal ride height regardless of what I was towing. The product absolutely does the job. My 27 ft 5th wheel makes the truck squat a good 6 inches. The airsprings restore the truck to its normal ride height in seconds. My justification for the 4 star rating rather than 5 is that the instructions make this install so black and white, when truly it takes some planning. The suggested install location wasn't going to work because of my 5th wheel brackets. Some easy modifications to my truck (small notch in the cross members that support the bed and the install was perfect. The install tool really does make things fool proof. I suggest attatching the bottom bracket with the install tool in place, then clamping the top bracket into place and drilling, as opossed to marking the holes.

Product installed very easy and works great but the packaging is another story. Heavy duty brackets are in the box loose with no separation from the air line or bags. My air line had some good scuffs not really what I want to see in something that will be holding air pressure. I emailed the company and they would not tell me if this is how it's packed or not. 5 stars for the product zero stars for packaging.

It seemed a bit intimidating when I opened the package and also read the instructions, but by going slowly I got the job done. I know I could do it a second time much more quickly, but you have to go slowly when you are new at something.I haven't had the opportunity yet to try them out with a heavy load in my pickup truck, but I have no doubt they'll do their job.

only took about 2 hours started it one day and finished it the next. no problems except had to purchase shorter bolts for the drivers side to prevent rubbing on the fuel and brake lines. I didn't want to use the self tapping bolts. I put a 1500 lb popup camper on it and wow does it carry it nice now. the only thing I didn't know when I ordered it is the instructions say it wont work with a certain 5th wheel hitch reese I think. other than that it was pretty easy and works great!

These are the perfect product to level out your vehicle when it has a heavy load. Even without the load these bags give the truck a better ride a much smoother ride with a load is the same outcome a very smooth ride highly recommend this product. I put it on a 2006 Chevy crew cab Silverado 4x4
