Pin Box Question

Is the trailer still under warranty. If so, you need to check with the manufacturer (not dealer) and see what hitch he recommends. With a Lippert frame, they may have an issue with one that they do not approve.

No experience with those (I have a 5th Airborne air ride pin box) but I will say I think air ride pin boxes are worth the money. Definitely softens the ride and reduces chucking if you have any.

We have a Trailair Tri glide. Very happy with it. It helped the chucking by probably 85 % .I Don't think Lippert will have an issue with Trail air because that's what they use.I also went with Bilstein 4600 shocks and Monroe shocks on trailer. We now have a very nice ride on choppy freeways and bridge transitions.

Our 5th wheel has a TrailAir tri-glide as original equipment. The tri-glide feature addresses fore/aft surging and chucking and is similar in design to the Demco GlideRide pinbox we had on our prior 2004 Mobile Suites 36RE3. As far as I'm concerned, if I'm going to address vertical loads with the airbag, I'm going to address the fore/aft loads as well with the tri-glide articulated loadplate/kingpin.

If towing level is an issue for you, say for instance your 3/4 ton diesel bed sits high, you should realize that a pin box swap will add an inch or two to your high nose. You could end up having to raise the trailer frame.

Lippert owns TrailAir. Can't see any warranty problems if you use their own product. I have a TrailAir with the Tri-Glide jaw. I'm thinking they might just discontinue the Tri-Glide soon now that the FlexAir version is out. Tri-Glide has 9 grease fittings you need to hit every thousand miles or so. FlexAir won't require that. My Tri-Glide bumps and bangs on starting and stopping at times. The brake control needs to be just right. There have been some issues with the Tr-Glide jaw coming apart. They develop a lot of sideways play in a few of them. I wouldn't buy another. JMHO

I just dont know if the tri-glide is worth the extra money.


I appreciate your input,

I have owned two of the TrailAir air bag kingpins with the TriGlide. They both work well and are worth it in my opinion.

Thanks for the information everyone. I think I am going to order the Trail air Flex Air.

Hope it performs as well as I have read in researching. My eyes hurt!

+1 on reporting.

I was trying to get a flex air last summer. But a manager at Lippert said they were not happy with the results of testing. Lippert offered a tri-glide at the Coachmen rally for less than $1100 installed (including providing and installing neverfail bushings) and I jumped at it.

I wanted something anyway. The plain trailair just wasn't getting the job done, my chucking was horrible. The Triglide has done a great job. I hope the flex air does a great job for you.
