-Airlift 1000 air bag kit install

-Finally bought a tire deflator and a big tire plug kit for my soft side case as well. Here’s the air bags I bought.
Amazon.com: AIR LIFT 60728 1000 Series Rear Air Spring Kit: Automotive





-It says not compatible with my 4Runner, because it’s an 8-1/2” bag and not a
6-1/2”. I went 2” longer due to my 2” rear lift.

-Used the bottle jack method on top of the axle to get the extra separation to get the spring out/in easier.


-Cut the bump stop in the last groove. It cuts pretty easy but you have to push it away from the knife to prevent pinching. I read where a lot of people had a hard time cutting it.


-Drilled out the base to route the airlines through. Deburred sharp edges when finished.




-Had a hell of a time getting the air bags into the springs. Took a lot of lube, prying and “influencing”! Spent a couple hours getting them in and a lot of hitting with 5lb sledge.


-Getting the springs back in and the airlines ran








I put the Scrhader valves underneath on the outside of my aftermarket HD tow bar to keep them out of sight. I used a Pneumadyne air valve switch to run them together or separate with the flip of a switch. I keep them running common all the time unless I need to load up with weight and need more stability. It makes it nice when airing up or checking psi. You can flip it to shared and you only have to use one valve, then flip back to single as needed.

I used JA’s method here from this link and got the idea about the air switch. Plus it has good information for the install as well.
