Speaker 1: Today on our 2011 Nissan Armada, we're going to be installing the Firestone Coil-Rite air helper springs, part number F4150.Now if you're looking at getting a set of airbags, these are some of the benefits you can get. Now if you have trailer or a load on your vehicle without airbags, it's going to sag the back end, lifting up the front. So your headlights won't be aimed properly. It'll also reduce braking performance and cause steering stability issues. Airbags will level out your vehicle, returning your headlights to the proper aim, return that steering and braking performance to factory, and also help level it out, so it looks good going down the road. They'll also provide a little bit more comfort and cushion while your vehicle's loaded up.These airbags are going to install directly into your existing coil springs.
It's made of an elastic polyurethane. So it's going to be pliable and easy to install inside your coil spring. It operates between five and 35 psi, to adjust the level of your vehicle depending on your load.Now when comparing these to other suspension enhancements for Armada on our website. This is going to be the most adjustable and best ride quality. As the other ones we offer are only a jounce style.
So it'll be a solid rubber bumper that has no adjustment and won't provide as much cushion.We're going to give you a few measurements before we install our springs. So you can see how they affect the vehicle. With the vehicle unloaded and it's factory suspension, it measures about 35 and 3/4 inches. And now to simulate a loaded trailer or cargo carrier, we've got some five gallon buckets fully loaded with sand. So it's adding a bunch of weight to the back of the vehicle.
Let's see how it affected our ride height. And that dropped us down to about 34 and 3/4 inches. So we're about an inch lower in the back than what we were.Now what this means is loading down the back, it's going to put more weight on the back of your vehicle, which is going to lift up on the front. So it's going to have an adverse effect on your steering and handling. It's going to feel a little bit squirrelly around the road.
And it's going to impede your braking performance. Now we're going to take it out on our road course and see how the weighted down suspensions going to respond.Now we're going to take it over some uneven speed bumps. This can simulate hitting some potholes. Now we're taking it over our straight speed bumps. This can simulate pulling in and out of a driveway. Now we're going to come into our slalom. This is going to simulate evasive maneuvers and turning.Now with our airbags set at about 32 psi and weight back on, right about 35 and 3/4 inches. So we're right back to our factory ride height when loaded up. This is going to return that loss steering stability and braking performance that we had before.To start your installation, you're going to need to collapse the cylinder. To collapse it, you can use a little piece of air line or you could cut a small piece off of the air line that's provided in the kit. Push it in the quick connect fitting, make sure it's fully all the way down. Collapse it and roll it up. This'll get all the air out of it making it easier to install inside your coil spring. Once you've got it collapsed, take the small plug provided in the kit and push it into the end of the hose. This'll prevent air from refilling up the cylinder.Here we're back at our coil spring. We're going to take our collapsed cylinder and in the lowest opening, we're going to push it inside the coil spring. Now if you're having difficulty getting it inside the coil spring, you can use a blunt object that has no sharp edges to help push it in there. A half inch extension works really well for this. Just continue to work it up in there. Sometimes it helps to twist it back and forth. Make sure you're getting over any lips that's hanging you up. Just keep working it up.Push your air line hose down and around inside your coil spring and have it poke out the bottom. Once you've got it in there, then you can release the vacuum on it by pulling the plug out. And this'll let the airbag fill back up. Then once it's filled up, it's fully in place.Now to remove the small hose that we inserted into the airbag. You simply push in on the ring at the bottom of the airbag. Push it upwards and that will release the hose from the fitting. You can just pull downwards. Now you'll repeat this same process on the other side.The next step will be to run your air line. Now typically you'd run your air line into the bumper. And there'll be two fitting provided in th
