Looking at a used Trailair tri-glide air ride pin box.
Any feed back would be appreciated.

We have the 5th Airborne air pinbox, no problems. Using it for 9yrs.

Check it for side to side movement. If tight it's in good condition. Some failures but MANY don't understand there are "9" ZERKS to grease.

Mine is rated at 21k, I tug on it with 23-25k full time for 4 years. Grease it PROPERLY and I doubt you will have issues.

Maybe they don't understand there are 9 zerks because the owner's manual says there are 6. At least, that was the case with my manual. After 3 years use, I could no longer move the mechanism fore and aft by hand so I looked closer and found the 3 zerks on the bottom. After greasing them, I could once again move the plate by hand.

I had the tri-glide and it was ok until it was close to failure.... I routinely greased all 9 points and started getting a ton of slop...

They (Lippert) replaced it with the Flex-Air and that was a real nice ride...

My new 5er has the Morryde pinbox and so far I really like it! Time will tell if I like it as much as the trailair

Any air ride is an improvement. We have a Hensley Trailer Saver BD3 and it's incredible.
