I installed the airlift1000 bags in my rear coils a few weeks ago. I’m running rancho shocks and heavy duty OME coils (LJ coils) on the rear. I have a heavy aftermarket bumper/tire swing with an aluminum fold down shelf and a full Tuffy underseat drawer (no backseat).
The OME LJ coils handle this everyday weight quite well but I needed something more for when loaded down on a extended trip or towing a trailer. My rear coils sagged 1.5-2” when fully loaded and it really felt like I was riding on an over compressed spring. I was experiencing too much body roll. I could feel this ‘body roll‘ from front to back as well when accelerating and braking.
Although I’ve only had the airbags for a few weeks I am very happy with them. For $85 I fixed my occasional sag and body roll issues. I’ve been fully loaded down once and the improvement in ride quality is significant on and off road (gravel/dirt road). Plus the 1.5-2” of sag is gone. I’m still figuring out what psi to run in them loaded vs unloaded. They can make for a jittery suspension if over inflated.
So I say that if you occasionally carry a load or tow a trailer, the air bags are a cheap reliable solution. If you’re just looking to improve you’re current ride quality and don’t plan on carrying varying load weights then get the appropriate shock and spring combo.
Hope this helps. Let me know if you have any questions.
