Convert your constrained 4CS Forks to a fully functioning compression and rebound circuit in both L/R Fork Legs. This kit allows the forks to have a functioning low speed circuit and have the desired plushness of any fork you have ever ridden!! While still maintaing the nice bottoming resistance of the 4CS Forks. They work great for Offroad and Moto applications dependent on tuning them for your type of riding. After installation, Compression adjuster (both sides) will be on the bottom and Rebound adjusters (both sides) will be on the top.
