Air ride hitch pins

For the money IMHO the TrailAir air bag kingpin is a great option. "RATED" at 21k, the TriGlide is great but that option is no linger available. People not understanding there were 9 grease points not 6 probably caused it's demise. I tow 23=-25k on mine full time for 3.5 years now.

Look at the geometry compared to the 5thAirborn.

Absolutely! We have the TrailerSaver BD3 purchased new in 2010. We inspect the setup before each trip and do maintenance annually. Well worth the ride and to save your trailer too!

We have the Reese 5th Airborne and love it. As donn0128 said, you need to make sure it's a fit. I know Reese has a page where you can get replacement parts

Has to be better than no air suspension. It has been reported that some air pin boxes lose their effectiveness with high pin weights as the air bag has to be pumped up to such high pressures.

Yes, definitely. But, since there different pin boxes you need to be sure this one will fit your trailer.
