Video Transcript for Firestone Ride-Rite Rear Air Helper Springs Installation - 2016 GMC Sierra 2500

Speaker 1: Today in our 2016 GMC Sierra 2500HD, we'll be having a look at and installing the Firestone Ride-Rite Red Label Extreme Duty Air Helper Springs, part number F2702 in conjunction with the Lift Spacers for Firestone Ride-Rite Air Helper Springs for vehicles with a two inch lift, part number F2366.Now here's what our airbags look like installed. These airbags will give us a low leveling capacity of up to 7,500 pounds. It will not increase our gross vehicle weight rating by 7,500 pounds, this will maintain our ride quality and ride height with 7,500 pounds of weight in the bed. You'll want to consult with your owners manual of your truck and see if the vehicle is capable of towing or hauling that much weight before you attempt to do so, you don't want to cause damage to your vehicle.These airbags support anywhere between 5 and 150 PSI of air pressure. Unlike a lot of other competitors airbags on the market these are actually designed to be able to have the rear axle fully suspended when the truck is raised in the air for service. Other airbags from different manufacturers sometimes require the axle to be supported and not have the full weight of it hanging down because it could damage the airbag itself.

On these you don't have to worry about that, so there is no special precautions you need take when you have your truck in for service such as a tire rotation.The first thing we want to do is get some measurements and see where our vehicle's ride height is. Now our vehicle does have a suspension lift on it so this will effect the measurements compared to your vehicle if it's factory. What we're gonna do, we'll measure from the center line of our wheel up to our wheel arch right here and record that measurement. Right now we have no weight in the bed of our truck. Okay, so we're at 45 and a half inches here in the rear and about 43 and a half in the front.Okay, now we have a substantial amount of weight in the bed of the truck, this will simulate carrying a heavy load or towing a heavy trailer like a Gooseneck or a fifth wheel with a heavy pin weight.

We'll double check our measurements and see where we stand. Okay, we're at 43 and a half inches right now and that means we came down about two inches in the back so our back end's going down and our front end's raising. Okay we're about 44 inches in the front which means we came up about a half inch in the front.What this is doing is when our back end comes down and our front end comes up our headlight angles changing, we're getting less weight over our front tires which means we have less steering and stability also less braking performance to help slow us down. Also our front tires are starting to camber out like this, this is what's called a positive camber. This will cause more tire wear on the outside edge of your tire.

Now with all of these things combined we could blind incoming drives with the headlight angle being more in their face versus down towards the road, we'll have decreased handling, decreased stability, decreased braking ability. All in all not a safe ride.Okay now that we have our airbags installed and our weight back in the bed of our truck we'll see if we're back at factory ride height. All right as you can see we're about at 45 and a half inches again. Okay, we're at 43 and a half inches in the front again, which is back to where our truck was with no weight in the back.Okay, now we'll take it our on our test course. On the left side of the screen you'll see what it was like without the airbags installed with the factory suspension and on the right hand side of the screen you'll see it with the airbags installed.

On the left hand side of the screen you can see how unstable it is when we're making evasive maneuvers, going around corners, or just making simple turns. You can also see when we're going over bumps or going over uneven surfaces how unstable it is and how much rebound there is in our suspension. On the right hand side of the screen you can see how much more stable it is when we're going around the corners, doing evasive maneuvering, how much less body roll there is. Also when we're going over the bumps you'll notice how much more stable it is and how much less rebound there is in the suspension, it's letting the suspension do its job and it's providing us a much smoother ride.Now that we've gone over some features we'll show you how to get it installed. All right here we are underneath our truck, we went ahead and removed our spare tire just to give us a little bit more room to work when we're filming. You don't need to have the spare tire removed when you're installing this.First thing we need to do is locate our bump stop right here. We need to remove this so we'll just take a screw driver, pop up, pull down, and remove. Okay now we'll take our upper frame bracket and our U-bolt and slide it in position just like that. Okay, now we'll take our frame bracket here, slide it around our bump stop bracket, make sure it sits flush against the bump stop, hold it tight against the bottom, and slide our U-bolt into position into the holes.All right now that we have our bracket in place with the U-bolt against the bump stop holding it in position we'll take our strap, slide it over our studs, place on a flat washer over each U-bolt, and we'll thread on our nylon lock nuts, and then we'll snug those down. Use a 9-16th socket when we tighten these down, make sure we go somewhat evenly. Then we'll torque them to the amount specified in the instructions.Now this part's gonna be different for most applications. This spacer block here is not included with our kit, this is sold separately as a kit, it's part number F2366. It's a two inch spacer designed for vehicles that have a suspension lift on them up to two inches. This way you're not stretching your airbags out. Our vehicle has a lift on it so that's why we're using this block. We'll flip our airbag over here, take a lock washer and bolt that comes with our spacer kit, center it over here, and drop the lock washer bolt down, and then we'll tighten it up. A flex head ratcheting wrench is really handy in this application.Okay, now we'll take our lower frame bracket and our pan head bolt here which has lock tight already on it and get it in there. I want to point out our fitting here is pushing away from the side that's uneven and not flat. We'll just have this finger tight for right now so we can make our adjustments later and mark where it needs to be.Now we'll take our fitting and we'll screw it into the top here and we'll tighten it down until the thread sealant on it engages. Okay, that's engaged more than half way so that's good. Okay now we'll raise our airbag assembly up into place. Our large stud here will go through the large hole and our alignment head will go through either the forward or the back hole here depending on which gives us the best fit. Okay I like the look of it going through the back hole so now we'll take our star lock washer here, go down over the stud, and secure a nut. We're just gonna do this finger tight so we can make our alignment marks.Okay we made a couple alignment marks here where everything's sitting nice and straight so now we can lower down our assembly and tighten down that pan head bolt on the bottom so our marks line up with that and then we can reinstall our assembly. We made sure our alignment marks that we made line up so we'll snug down this bolt fully to the amount specified in the instructions and we can reinstall our assembly now.Okay with this nut finger tight now we can tighten it down and torque it to the specifications found in the instructions. Now we'll drop down our carriage bolts, making sure they go between our axle and brake line so one on each side. Okay now we'll take our axle strap and install it onto our bolts that we dropped down, place on a flat washer and a nylon lock nut. Okay now we'll take our final U-bolt, stick it between our wheel and our suspension here on the axle, make sure we don't pinch our ABS wire here, and we'll bring it into place through the holes right here.Now that we're through both sides we'll place on a flat washer and then a nylon lock nut. Make sure we do the same on both sides. Okay, now we'll work on tightening down our nuts. With all of our nuts tightened up now we'll torque them the amount specified in the instructions. We want to make sure we tighten these in the even manner. We do a little bit on one, then go to an opposite one and do the same.Okay we went ahead and repeated the same process for the passengers side in order to get our airbag assembly in place with one minor exception. We installed our heat shield here to protect your airbag from the exhaust in between the bottom of our top mounting bracket here, in between the top of our airbag assembly. There's a large, round hole it just sits on top of, it goes into place and you secure it with your hardware on top.We need to find a place where we can mount our airline fittings. We also need to make the decision at this point if we're going to have one fitting or two fittings. If we have two fittings we can fill up each of our airbags separately to help stabilize heavier loads that are on one side of the truck. Now we can mount them with our no-drill bracket here, which you could attach to your hitch with the included zip ties or for a cleaner look that's higher up with no ground clearance issues we can install them in our bumper by drilling a hole. I'm gonna put them in front of our license plate lights right here in this area, however our customer is putting in a compressor at a later date and the compressor's single stage which means it can only control one path of air, so I'm only gonna be using one fitting. I will tie both of our airbags together with a T fitting.I've already verified that there's nothing in this area that I'm drilling into that's gonna get damaged so I'll drill our 5-16th of an inch diameter hole. Now we'll take our air valve, undo the nut, place on one of our 5-16th flat washers, reach up and behind the bumper, stick it through the hole, place on another 5-16th washer, and reinstall our nut. Then I'll hold it in place on the backside of a wrench and tighten down the nut here with a socket. Once we have that snugged up we can start routing our plumbing.All right, so we'll take our airline tubing here, we'll use an airline tubing cutter which we have available on our website as part number F9009 to ensure that we have a straight, clean cut on the end, just take a little bit off. Take our tubing, push it straight down into our fitting until it stops and we'll pull back to make sure it's secure.Passengers side is a little bit different. We have this protective heat shielding here that we're going to slide on over our tubing, this will help protect it from the exhaust. We have two pieces that come with our kit, we'll use both of them and we'll push into our fitting just like we did on the other side, make sure it's secure. Okay once it's in place we have our heat shielding right here down to our nozzle.Okay our drivers side we just have leaving our valve, secured it with a zip tie around this wiring harness, and it comes out right here at the center part of our cross member here on our frame. I'll show you the passengers side now. Okay, our passengers side one we have it secured here to a wiring harness for the ABS sensor. It comes across our cross tube here in the frame and it ends right next to where our drivers side one is.Where our lines both end this is where we're gonna install our T-fitting to combined them into one. It works the same way as the others, you just push in until it stops and pull back. Make sure it's secure and make sure we have a clean cut again. Then I'll measure off how much we're gonna need, cut off the excess, and plug it into our fitting. Now our line that goes from the inflation valve, we just went above our spare tire carrier here and then T'd into our fitting.Now that all of our connections have been made we can add air to our system and check for leaks. All right now how we're gonna check for leaks is quite simple. We'll use some soapy water and spray where our airlines go into our fittings and check for any bubbles. If we see bubbles that means we have a leak, if we don't that means we're good. Okay, with no leaks anywhere that means we're good to go and we're ready to use our airbags.Now that completes our look at and installation of the Firestone Ride-Rite Red Label Extreme Duty Air Helper Springs, part number F2702 in conjunction with the Lift Spacers for Firestone Ride-Rite Air Helper Springs for vehicles with a two inch lift, part number F2366 on our 2016 GMC Sierra 2500.

Lift Spacers for Firestone Ride-Rite Air Helper Springs - 2" Spacers - Qty 2 - F2366

Average Customer Rating:  4.9 out of 5 stars   (20 Customer Reviews)

Install Ride-Rite air springs on a lifted vehicle with these lift spacers. Spacers attach between the bottom of the lower bracket and the bottom of the spring on vehicles with a 2" lift. Kit fits air springs that mount on axle or leaf stack.


Worked just fine. Had to purchase because truck had rough country 3" lift, although it only had 2" blocks for rear. Spacers seemed to be great quality. Was not impressed for how long shipping took. The bags only took 2 days. And it would be nice if there was a better warning I needed spacers for my air bags. It says compatible with lifts but that was it. So when I went to install, I had to take them back off and look it up. That's when I found they made spacers. I have to add I LOVE My Firestone Air suspension. When I hooked up to trailer, truck dropped 7"s. With airbags and 45lbs of air, dropped 2"s and ride was smooth.

After a year, bags still work just as well as they did the 1st day. So far I still havent had any air leaks or blessing off. It stays where I put it. I have a half tone truck. I just hauled 1 12 ton of top soil with 60lb of air and truck rode level. Even the guy on the loader complemented suspension. Next I would like to add controls from the cab or my phone so I dont have to use the air hose every time to change it.

I just finished the installation of the air springs and spacers. All the parts were there, the instructions were easy to follow and all went well. I look forward to hooking up the fifth wheel or loading up with firewood. Thanks for the excellent service and the additional help answering my questions about the spacer kit to accommodate the lift on my truck.

The air bags are holding up well with no problems.
Terry D - 07/09/2021


Top notch customer service! And product performs flawlessly time after time with 5k payload on spacers and airbags!! Couldn't be Happier Thank you ETRAILER!!!


Etrailer was really helpful in finding the right product for me. The blocks installed easily and worked really welll


I ordered the air bag extensions and they are still solid and working as they should. I got them on time no hassle at all.


Exactly what I ordered with super fast shipping. Can't wait for my extension brackets to come in and install it on my truck


Quality part and quick delivery. I’ll definitely be ordering from again.


These spacers were just what I needed after I modified the suspension on my old Chevy pickup. I bagged and 4 linked the rear but it was just a little too low, using these spacers got my ride height where it needed to be.


Worked great on my AT4


Still going strong
Edward.C - 05/11/2022
