Stick stoppers help prevent one of the most common and costly atv repairs, broken axles. Most broken axles that we see are due to the cv boot being damaged which allows the grease to run out or lets sand and water into the joint which causes failure. Stick Stoppers are a simple concept, they bolt onto your factory A-Arms and provide protection where your bike needs it most. Note: These stick stoppers are intended to work on OEM arms with factory suspensions. In most cases a bracket lift will still work with these arms but may need minor trimming or modification of the stick stoppers to avoid clearance issues.
