Hey this is Clint with Inner Air Lock wanted to say hello and if I can help answer some questions!
Yes the Inner Air's are completely different than staun.
The first its a US company. The castings that hold the tube are completely different.They are made of a poly coated nylon.The thread used is military grade high tensile nylon thread.
Our tubes are different they are radial tube that can be found at any ATV or motorcycle shop if needed.You have to go to Staun for there tube's. The other difference is in the casting for the air delivery for tire pressure these (do not) have the air way flap like Stauns.
We have found with a x grove in the valve stem you can still air up and down the tire with out the air delivery flap!Witch is one less thing you have to worry about when putting them together.
Also some of the Inner Airlocks are interchangeable.The Airlock for an 8" rim will work on a 10" rim and you also can use a rubber valve stem for the tire so there is no breaking it off in the rock's.Also Inner Air Lock makes locks for a 12'' wide rim and Inner Air Lock is the only one making a lock for a 16.5 rim that works!Staun recalled all of there's.
Also we have some awesome 1/4'' thick weld in ROCK RINGS to help beef up your steel rims.
I hope this helps with Q's please call the shop, Shawn is happy to answer any Q's for you 231-313-0661 and our web site shows step by step with pics on how to install
