Broken rocker arms two weekends in a row

If it was me I would double check your geometry and simple stuff so you know it isn’t on you. Getting off and on the throttle did not cause this because that’s what racers do. If you would hear my son at the finish line and every other good racer you know that. Our season is almost over now so I would talk to the Mopar guy at Harland Sharp (I forget his name) and I would box them up and send them to them for testing. Both being exhaust rockers makes me go hmmmm.
Hi John,
Yeah, I didn’t think that would have caused it to break. I put a call into Randy at HS and am waiting for him to call me back. I gave the broken rocker arms to the gentleman I bought the Arrow from as he is a machinist by trade and wanted to do some testing on them. His findings are no fretting or stress cracks in the aluminum. His opinion is they’ve just reached the end of their service life and should be replaced, at least the exhaust rockers.
