Our records on this specific part number are thin — we don't have detailed catalog history or figure references to pin down exact model or year fitment. If you're ordering for a specific engine, give us the details on the bike and cylinder head you're working with and we'll confirm this is the right rocker arm before it ships.
If you already know which side and which valve (intake or exhaust) you need, mention that too, since rocker arms often differ from one another even within the same head.
