I have run the 46,000 pound suspension quite a bit on the haul road, I prefer the nuway, but airliner is right their with it as far as ride, durability and traction under sever use . It would be my second choice well above all others.
I've ran it in logging, walking floor and tri-axle dump trucks and have had no issues. Ride is good, it is stable, truck stays level (doesn't lean like some others I see), has chain clearance and has been pretty reliable.
I’ve had 2 so far on Classics, After 15 yrs My current Truck needed bushings. Not bad, I used ATRO polyurethaning anti- walk bushings. Much harder material ( like plastic) but grooved to resist walking out of the bushing. Whole job w/ labor only $500-$600. Only maintenance item on suspension.Had Hendrickson on my 92 star. Looked similar in design but rode rough. Neway is popular, and loved by most. To Me it’s similar to lo- Ride Pete suspension.Not a big fan of those myself. Kw 8 bag- never, I’d have to put an airliner on a KW if I bought one. Lol Airliners simple and rides good. Maintenance free for years. I’d go with it, myself.
