This started as a one-of-a-kind set of these "Gen 1" Angus Roller Rockers for myself and have taken off!  Since they first came out in August of 2001, these have been talked about on practically every 3.0L forum.  Some still don't believe they exist or are available in the U.S., but they are.  Now in their 2nd incarnation, these "Gen 2" Roller Rockers are a complete system.  None of the problems associated with the older versions exist.  No more shimming or worries about head/deck shaving or headaches shimming if you replace the cam.   These new rockers are complete with new studs, rockers and locking adjuster nuts.  Complete with instructions and only available through Rogue Performance and "stuffforyourranger.com"
