I have the TrailAire and it does a great job minimizing chucking. However air pressure is very important. I found that when it is underinflated the chucking is more noticeable. Also the shock absorber must be in good working order. Like most shocks they wear out. Oil leakage is generally a sign of failure, but not always. Like all shocks. BTY TrailAir has two verisons one with and one without a rubber damper like the MorRide. I have the one without and is probably the reason why air pressure in the air spring is more critical.
