SO the pinching problem starts when the rear end articulates and I have the red Air bag in the spring and rubber bumper between the air bag and bottom spring mount. The hose stretches and comes back in place and some how pinches there. I've put grease and left about 4inch of hose for play. It has pinch twice off roading. I know this is the problem area but can't find a solution.You might want to look at how your lines are routed, I've got Airlift 1000's in the back of my LJ and have done about 500 trail miles per year for the past 6 or 7 years with no issues with the lines. I highly recommend the AirLift bags for running an RTT and fridge/kitchen on an overland TJ/LJ.
How much pressure do you keep in them? You really need at least 10psi in them at all times to keep them from moving around inside the spring. Any less than that and they're likely to spin in the spring and twist the air line.SO the pinching problem starts when the rear end articulates and I have the red Air bag in the spring and rubber bumper between the air bag and bottom spring mount.

That's exactly what I do. It only goes in maybe a couple days per year.
