Shock combo has the conventional steel spring in 1 shock and unique dual air chamber in the other shock
The dual air chamber shock allows the rider to put the correct amount of air in one chamber for the rider’s weight, passenger, etc. and the second air chamber is for the rider who wants to set the ride height
This setup allows the load carrying air chamber to retain its pressure allowing bottoming resistance when lowered
Airtail Shocks come complete with a manual fill valve and ready to install
