COMING SOON! Airlift is actively working on an upgrade for the rear coil suspension for your 2025 Toyota 4Runner. We'll update info as we get it. Preorder now for quickest delivery.
Features:
Specs:
Heavy loads can cause the back of your vehicle to sag and add unnecessary stress to your suspension. This stress not only affects your brakes in a bad way, but your tires, headlight aim and handling suffer as well. To improve your vehicle's ability to endure heavy loads, you need to add support to your existing coil springs.
Air Lift's AirLift 1000 adjustable air springs have 1,000 pounds of load-leveling capacity and are made specifically to fit inside your rear coil spring suspension for additional load assistance. You can inflate and deflate these tough, molded polyurethane helper springs as needed, ensuring the perfect amount of support for every load, every time. Easily level your vehicle front to rear, and if you run dual air lines to the air springs at installation, then you can inflate the springs independently of one another for side-to-side leveling. AirLift 1000 is a breeze to install with standard tools and comes with an easy-to-follow instruction manual.
AirLift 1000 comes with manual inflation valves that are typically mounted on the bumper but can be installed anywhere on your vehicle for easy access. For even more convenience and control, you can add a compressor and gauge system (sold separately), which will let you monitor and automatically inflate your air springs.
Air Lift kits are designed to keep your vehicle at normal ride height. You can find the normal ride height of your vehicle by unloading it and measuring the distance between the bottom edge of your wheel well and the center of the hub. After you find and record this distance, you can regulate the amount of air that you put into your air springs to maintain normal ride height - even when you are hauling a heavy load. You will need to adjust the air pressure in your air bags according to the size of your load.
Air Lift is positive that you will benefit from their air spring suspension system - so much so that they offer a 60-day satisfaction guarantee. Install and use AirLift 1000 springs for 60 days, and if you are not satisfied at the end of this time, you can remove them from your vehicle and return them for a full product refund.

Glad to hear they are making towing a more comfortable experience, Mark! Cool little camper as well! ^___^ Where did you guys take it?

The helpers look great on your Hummer, Rob! What kind of travel trailer are you hauling?

I have towed my RV several times over the last year and these helper springs work perfectly! I had a very small air leak but I added some silicone at the airline connections and it is 100 percent! I carry a battery powered air compressor with me and it’s basically a “set it and forget it” systems.

Glad they are working well for you, Scott! I gotta ask, did you do the AHC delete as it was worn our or did you just not particularly like it? I've heard people do this for either reason.

The air springs are still operating as well as the day I installed them. They do not leak any air pressure nor have they degraded in any way. What a great and simple solution that lasts.

Well, after going back and forth - basically it comes down to - 60 day drive warranty doesnt compute. So after spending $300 on install, now Im expected to spend another $300-$400 to have them removed to return them, oh and pay for return. So roughly $800 to get back $130. Ill chalk this up to understanding that if a product doesnt work out in any manner. To remove these, you have to take the rearend of the car off - shocks and springs - then try to get the bags out of a much smaller ending without damaging otherwise youll not refund. Basically no support, other than a were sorry.

Thanks for the great follow-up review, Jimmy! Glad to hear the system made such a noticeable difference in both ride quality and suspension support, even when you’re not towing. It’s also great to hear the install videos helped out along the way. Air connections can definitely be the most finicky part of the install, so we appreciate you mentioning that for others considering the setup. Sounds like the end result was well worth the effort on your Pathfinder. Thanks again for sharing your experience a year later!
