Welcome to CA csuehs77!
You can install the aftermarket air bags, but the plumbing (hose diameter) are different which makes for different issues. I would suggest tracing down the source of the leak and then making your decision. It is very rarely an issue with the air shock itself but rather the connections or the hoses that leak. Is it throwing any codes? I know there are some codes it will throw if there are issues with the electrical components. I'm not sure if anyone on here has swapped out air bags yet... some of us have been contemplating it and in theory we should be able to rip out the system all the way through the air compressor and install new bags, lines, and compressor and hook it up to the existing height sensors.
